I have an answer on my mind. It is a bit technical and capital consuming one, but i assure you it is one of many revolutionizing yet implementable ideas. It is not a new idea but was not given the necessary importance at the right time.
Indian Railways stands proudly as the world’s Quatrième longest rail network (world’s seconde largest network operated under a single management) with >1.4 million employees on its rolls (world's septième largest employer). But, if we talk in the language of speed — We décalage by manifold. While various countries are using advanced tech to drive at speeds far greater than 300 km/h, we still use colonial-era technology (Of course by making it efficient). We, for sure can go far higher than what we are now with Gatimaan or Tejas.
The avg. speed of a normal train is ≤90 km/h (which is tristement not achieved in majority of rail stretches). The reasons for this may range from ‘Traffic Congestion on the stretch’ to ‘Speed restrictions within small intervals’. There is one more reason that makes our trains slow… — And the reason is “Our Locomotives”. I’m not talking about the power output or the efficiency here.
Present IR locomotives are powerful, faster, efficient than ever, but… A locomotive or two in the front, dragging a line of passenger coaches/compartments is an old technology followed til-date. Many countries do not use this tech anymore.
- Dire Hi to — ‘Train Sets’ or simply speaking ‘Multiple-unit Trains’
Like DMU or UEM trains that run without a locomotive, these ‘Train Sets’ also have independent traction motors for each bogie underneath every compartment that move the train on one synchronous go.
Why these should be used? you may ask
Let’s see the advantages:
- They provide very good Accélération
- Acceleration is crucial influencing factor in making a train slow. In IR, average stoppage count for a normal train per kilometer on an international relative scale is very high (Top reason: High number of stations; Other reasons: heavy traffic, speed restriction, lack of empty platform etc etc)
- Once stopped, Trains take a lot of time to accelerate and attain needed speed — which consumes considerable amount of time (this is because the entire load is thrust forward by a single locomotive). But, this is not the same with ‘Train Sets’
- All coaches of a train-set accelerate at once, which allow them to reach their top speed in a very small time-span
Let me show an exemple for this—
Considérons un Rajdhani Train with 21 compartments behind a locomotive. It takes ~216 sec to reach 130 km/h, whereas the same with ‘Train-set’ take <40 seconds.
- Our current trains take a lot of time to stop after brake application. Even after braking, trains travel significant distance before halt
- Our trains use air-brakes or vacuum-brakes, where a long pipe (that typically starts at a locomotive) is connected til the very end.
- When pilot applies the brake, it takes a lot of time for the end compartment to stop (this is because of the time lag). Passengers suddenly feel an annoying uncomfortable jerk
- Electro-pneumatic braking system of train-sets cut the halt time by more than half (sometimes to 1/4th)
- L'efficacité énergétique
- Train-sets/Multiple-unit technology is energy efficient in comparison to regular loco based units. Using these we can save on a lot of energy
- They use traction motor based propulsion under every coach which eliminates the need for a bulky-heavy-locomotive and generator car. This elimination further reduces the overall weight — Thus, increased energy efficiency
- Aerodynamic design lets them use 25% less energy compared to normal trains
- Even under frequent braking conditions, Regenerative braking helps and allows save 17–25% energy
- As these trains stop fast (thanks to Electro-pneumatic braking system), any tragedy or mishap during emergencies can be averted/minimized
- Automatic door closing systems make the ride safe for passengers
- Micro-processor based diagnostic and monitoring systems identify and indicate the electro-mechanical faults within no time
- These trains cost almost the same in terms of maintenance as regular trains
These trains benefit the passenger for sure, alongside they can make positive monetary returns for IR
You say “They are very costly. So, we shouldn’t use them!”
- contrairement à Trains à grande vitesse, These train-sets are not at all very expensive
- Almost all European countries use these kind of trains (as both passager et Inter-city trains).
- In India, they can surely benefit normal trains, alongside they can also help premium trains like Gatimaan, Tejas, Shatabdi, Rajdhani reach average speeds of 200 km/h (without changing any existing track layouts and conditions)
- They don’t need any new type of coaches. As current LHB coach designs can easily withstand 200 km/h, the only kink is redesigning the compartments such that the propulsion system fits beneath the coaches
In the end, One good news —
IR is now focusing in the right direction and Integral coach factory started experimenting and manufacturing these train-sets. If railways establish a dedicated schedule, we can soon see their glitter on our very tracks.
I don’t know whether a common man can afford a bullet train, but it is clear that if IR adopts this tech, a common man can, in future ride at 160 km/h at low costs.
- This below news article of 20 June 2017, is the motivation for me to write this answer
- Also, Thanks for motivation iGYANKOSH
Happy to see that IR and Finance Ministry has approved manufacturing of Train-sets in Budget 2018–19.
In the Union Budget 2018, Arun Jaitley (Ministre des Finances) announced that modern engine-less train-sets with state-of-the-art features and amenities are being designed at the ICF in Perambur, and the first such set will be commissioned this fiscal.
Selon The Hindu: Sources from the ICF said that in the new train-sets, the locomotive will be replaced with driver cabins at either end of the train. They will travel at 160 km per hour, which is known as semi-high speed in chemin de fer parlance.

By being responsible citizen.
Knowing our power as railway consumers and taking actions against unethical acts.
I will talk about two of my recent travel snippets.
1. Traveling to Mumbai in Janta express : AC 2
After boarding train, I got bedding and the blanket was really dusty.
I asked for clean one and got reply “Madam sb aisa hi hai,mahine main dhulta hai ”(mam all are same, and get washed once in a month ).And this was the time when news channels were buzzing with railway blanket issue. Couple of minutes in train and got news update on cell “Railway will now wash blankets daily” .
Anyways, let’s jump to real action.
I had read about railway menu card in one of the facebook post : https://www.facebook.com/permali...
It was evening, I asked attendant for menu card. To my surprise he answered , “Menu card? Wo mere pass nai hai” (menu card? I don’t have that)
Me : Bhiya jhoot mat bolo, mujhe menu card chahiye(Don’t lie, I want menu card)
Préposé : Nai hai, gir gaya jo tha.(I don’t have, It fell down )
Me : Accha? Kaafi sare menu card hote hai bhiya,ullu mat banao (Really? Don’t you fool me, there are many menu cards).
He got angry and went away.
I went to TT(TTE : Train Ticket Examiner) who was few seats away and told him about the whole argument.
TT assured me of menu card.
Few minutes later same attendant came, with huge smile on his face.
And this was the menu card which he gave, and very softly said : madam jo bologe milega
(you will get whatever you want to order).
To my surprise normal tea was just for Rs 5(And they sell it for 10)
Me : Bhiya chay milega? Chini kam? (Can I get tea? less sugar?)
Préposé : Haan madam milega naa (Yes, why not )
And guess what, he came with tea in thermos.
It was the best tea I ever had in Indian rails.
Also, I did mention everything in Complaint book, which is there with TT.
Railway takes this book very seriously, TT gave me only after asking couple of times.
Rappelles toi, No matter what they say, this book is with them and they are supposed to give you when asked.
2. Traveling in Secunderabad – Pune Shatabdi express : CC (Chair Car)
I and my friend Rajneeta Srivastav were travelling to Pune after an awesome trip to Hyderabad.
I told her about “Menu Card ” and my menu card story of Janta express. We were not sure if we can get menu card for Shatabdi , as it is supposed to be standard one.
We googled and found there sure was menu instructions for Shatabdi/ Rajdhani too.
We were Very déçu avec propreté and service, its god damn Shatabdi express.
Pendant ce temps, I got call from Indian railway customer service to rate service and cleanliness.
(Yes, do expect call from Indian railway while traveling. My humble request,please do not disconnect and please give your ratings)
We asked attendant for menu card, and as usual our request was ignored multiple times. We thought of taking a walk in train and go get that menu card.
We went near EC(Executive AC Chair Car) and managed to get menu card:
We matched every served item with menu card and to our shock many things were missing , Also quality was really poor.
We decided to write complaint (we did try calling complaint cell but our call did not went through).
We asked TT for complaint book, he literally ignored our request.
We asked him many times and at last he got irked.
He took us to attendants and said: “These girls are determined to write complaint ,please call your supervisor”.
Right there was standing an amazing person (he was retired railway officer)who overheard our conversation.
He came to our support and told TT : “what is this going on, give them book . Beta aap log jaao baitho(kids , go have seat),you are customer he will come to you with book .Don’t trouble these girls , I know Suresh Prabhu will call him if you guys misbehave.”
We went back to our seat and wrote down our complaint.
And CC(Chair Car) was open battle ground, many fellow passengers asked for book to lodge their complaint.
TT was like : “Haan sbko de raha, ek ek krke sb likh dena ” .(Yes okay, I am giving it to everyone. Write one by one.)
Remarque:There are two books one with TT that’s for Indian Railway and one with
catering supervisor, that’s for IRCTC, ask for both.
Online Compliant status (got mail from IRCTC with guidelines to track complaint):
Mail on actions taken:
JUST THINK ABOUT IT . What will happen if we all make use of these small rights/powers given to us. This will surely make railway better .
So be bold and write
NOTE : You can sue IRCTC too , You are customer .Read about it.

182 for RPF, 138 for customer care, 1800111321 for catering, 0119856948644534 for ticket booking related issues. [email protected] for i tickets, [email protected] for cancellation of e-tickets, [email protected] for season ticket related issue, [email protected] for feedback, [email protected] for SBI card related issues, [email protected] for shouting and finally blah blah blah for blah blah blah. What is this? Common citizens travel in IR and not super humans with exceptional memory power! Single contact number like 911 or 100 for the travelers to submit all of their complaints, queries and feedback. Similarly one single e-mail id for everything. Sorting the issue out based of catering, service, behavior, ticket type is your job! Why are we flooding in our complaints to the twitter handle @RailMinIndia? Because it is a single stop solution for ALL THE PROBLEMS. Every complaint should be answered firstly by a human being, just like how they do with the 911 calls. The urgency in the caller’s voice can only be judged by a human being rather than any machine.
Changing colonial names
I am from Thrissur (Kerala). The origin of the name Thrissur comes from Thiru-Shiva-Per-Ur meaning The Town with the name of the Lord Shiva. The name owes itself to the most prominent feature of the city, that is the Vadakkumnathan Temple 1300 years old. Britishers changed it to Trichur and the railway code for the same in IRCTC website is TCR. This is just one example. Chennai Central station code is MAS. Kollam station code is QLN (Britishers named it Quilon since they couldn't pronounce it Kollam). Similarly, the names like gangman, loco pilot. Why can’t the gangman have an Indian names like Patri Sahayak or Rail Master?
Compulsory mobile charging port in every deck of every coach
One port in each deck (in each deck of 8 people). This is inevitable. Watching a movie in your laptop is not a necessity but the destination call alert, TWITTER handle, RPF 182 is all useless if the traveler's mobile gets switched off.
Fixed entry points to platforms like in Airports
Cover the entire station like metros or with truss work and restrict entry exit through multiple fixed points. Introduce scanner machines in all those entry and exit points. Recently I visited Nagpur station, there was a scanner machine at one point and 20 mtrs away was the entry point. I and most of the other passengers didn’t bother scanning their luggage. We can also introduce checking platform tickets or traveling tickets at the entry points. This will reduce the rush in platforms (seeing off mess can be reduced), increase revenue with platform tickets and also help us avoid incidences like the terrorist attacks.
App and web based parcel bookings
Any one who has ever tried to book a bike or scooter via Indian Railways knows the degree of mess, the expense and the difficulties. Booking a parcel is like going for a week's tour to China without any guide or zero knowledge about the local language. You don't have any idea about who is in-charge, which is the counter where you need to pay and what is the procedure. But everyone inside the parcel office is like I am the one in-charge, every counter is like this is where you need to pay. An App or website based parcel booking was needed 10 years ago. We are well behind. We are a growing economy and globalization has helped us in increasing our outreach all around the globe. Our young generation moves around fearlessly inside our country and IR and its parcel service is of utmost importance in this. I have booked parcel in 9 different stations, the situation is palpable everywhere except in Gondia and Nagpur. The kind of attitude the parcel officer had, plus the money taken by the clerk, the officer, the coolie and then finally at the counter all-together adds up-to a fortune. We are unaware of the instructions to be followed, it is neither standardized and if it is, it is still light-year away from the public. And because people are moving from one location to the other, they don’t bother giving a complaint too. They somehow want to get their things done. Kindly start an app or a website like the current ticket booking website to stop this lobby so that travelers can easily book the parcel, pay the price of all activities namely - packing the vehicle, booking the parcel, loading and unloading the parcel. Please ensure that all these activities are included so that the travelers don't even have to open their purse in the parcel offices when they go to give the bike. The moment travelers open purse they start sucking all the money. The maximum money is eaten up in the name of loading and unloading.
Lampes de lecture
I used to find this in Rajdhani and 2AC. Every berth (or at least Side Upper, SL, Upper and middle berth) should be equipped with a simple LED reading lamp fixed near the berth so that we could read even in late nights without disturbing our fellow passengers. We could also have a Library on Wheels which has a collection of the rarest of the rarest rich literature of our country (like hospital on wheels) so that people in all parts of the country gets at least one chance to keep their hands on the same.
Ramps (getting introduced now along with escalators)
They make mobility so easier. Imagine reaching 1st platform within 5 minutes to departure of the train with kids and a lot of luggage. If your train is in platform no. 8 all you can do is sit and watch. Even if you spent you have a trolley bag, the staircases will stop your run. Enter coolie! With the lovely humane-ness redefining behavior of coolies, I wonder how many Indians will be able to strike a fair deal with them. The jugaad-less, street smart-less, law abiding citizen of this country will have to give it to the coolie to decide on what the rate.
Ramps plus hand trolleys if introduced properly at least in the most crowed stations, will reduce a lot of people coming to see off travelers into the platform. Once these 2 are implemented the next step is to physically build a structure that will restrict the entry into the platforms through fixed entry points (next point).
Social Services - Financial burden (IR is considering this)
Railways bear social service obligation of around Rs 25,000 crore every year. This is done by carrying passenger and goods services below cost. Net Social Service Obligation borne by IR in 2013-14 is assessed at Rs 21,391 crore. Areas where service obligations are provided are mentioned below and possible solutions:
Problème: Passenger concessions. Solution: There is a total of 53 different categories for whom concessions are provided by Indian Railways. A stringent re-look into the same should be done. I believe concession only in terms of economic ground must be provided (it is my personal opinion). Plus concessions to people working in the IRs and their dependents must be totally stopped. This logic doesn’t appeal much to me. Should a police constable’s child be given a concession on the punishment for a crime s/he committed? Plus concession cost for students from different states, different government departments should be borne by the respective departments.
Short distance sleeper trains
Trains with running time less that 12 hours which travel over night could be converted into sleeper trains. This is an idea copied from Japan Railways. However, this would mean manufacturing these type of coaches in India or importing them from Japan or other countries, so the cost factor is not being considered here. But trains like Jamshedpur – Nagpur, Kochi – Chennai could be tried with all these coaches. One issue is regarding the privacy. Safety of all passengers is a concern in this.
Short distance sitting trains (Tejas)
The short distance trains like Chennai – Bangalore, Ernamkulam - Trivandrum should be converted to sitting trains completely. All trains travelling under 800 km could be made sitting. Sitting compartments means double the passengers in the same coach. More people = More revenue.
Differently abled (physically)
The answers given here is by train lovers but one thing that is common is that none of us have focused much on how the differently abled people’s travel can be made easier. I don’t even know if the width of doors in the AC coaches is wide enough to allow smooth passage of a wheel chair.
Wi-Fi connectivity (only in stations and important stretches)
I don’t support the move to provide wi-fi in moving trains. While travelling I have never got proper connectivity using internet, plus spending a lot of money on that I believe would be futile. Instead if that money and energy is spent on giving high speed free internet for 30 minutes for every user, even when the train reaches a station, all important jobs to be done via the internet could be done. Also rather than giving internet through out the running distance, important stretches could be provided with internet and the same could be announced while the stretch is approaching. I loved the wonderful conversations I used to have with fellow passengers in train, knowing and learning about India. Don’t let this die.
UR Ticket vending machine (implemented on trial basis)
Un-reserved tickets is a nightmare for every travelers in India. UR journey’s are decided in haste and we usually arrive 5-10 minutes before the departure of the train and the length of the queue which you are welcomed by is totally dependent on your luck. If we can swipe out cards and get money out of ATM machines, can't we install a machine to get UR tickets?
One basket at Each deck (implemented on trial basis)
We need a waste basket in all decks (below the tables). However, I must confess that implementing this is won't bring a change in attitude overnight. But this will at least help the concerned travelers. I have seen travelers keeping paper waste in their bags to throw this in to dustbins when they find, but the food waste? I hope the step of one waste basket in every deck will also promote a few responsible citizens questioning the ones throwing waste in to the tracks. However, in chair cars and UR coaches, I don’t know how this is going to be implemented. There seems to be no other way. Deploying a group of people to clean the waste thrown has to be continued as of now, but in the long run this step is irrational in a country with 115,000 km of track length (approximately circle the earth 1.5 times). However, in chair cars and UR coaches, I don’t know how this is going to be implemented.
Solar panel (already initiated)
Solar panel on trains (implemented on trial basis)
This is a new initiative by Indian Railways. Implemented on a trial basis in the Pathankot-Jogindernagar route in Kangra Valley section and Kalka-Shimla section of railways is completely solar energy powered trains. One of the major concerns railway faces in this is regarding the possibility of the solar panels being stolen away during its run.

Here is a very practical and profitable thought.
TURNING BLACK MONEY INTO WHITE MONEY AND YET, MAKING MONEY WITH INDIAN RAILWAYS
This is one of those ideas which emerges out of observing real situations, situations where it is as clear as it can get that the solution pre-suggested is just not working and one needs to adapt and innovate. This is a story of a typical Indian train.
You walk into the sleeper class of any train after nine a.m. and you are sure to see at least (let us stress on that) 4 people on the berths which are meant for three people. So, if you have a berth in sleeper class, anyone can just come over to your berth and ask you to 'adjust' for a little while and that the station they have to get down at is just an hour away. What these people don't see is that there is a fresh batch of such people on every station and you end up adjusting the entire day. Most people don't mind this. Problems start when people per berth go higher than 4.
Please note that I am only talking about the day hours in this entire pos
