India’s first hydrogen train: RDSO completes performance test of fuel cell and battery
RDSO said this test is aimed at matching the drive cycle simulation for the proposed Jind-Sonipat route and marks the completion of the stationary testing phase for the Driving Motor Coach subassemblies.

The Research Designs & Standards Organization (RDSO), the R&D body under the Ministry of Railways, announced on LinkedIn on August 29 that it has conducted a crucial performance test of the fuel cell and battery systems for India’s first hydrogen train.
This test, it said, which is aimed at matching the drive cycle simulation for the proposed Jind-Sonipat route, marks the completion of the stationary testing phase for the Driving Motor Coach subassemblies.
The hydrogen train represents a significant milestone in India’s push towards greener and more sustainable rail transport. The successful completion of this performance test is a key step in the train’s development process, ensuring that its fuel cell and battery systems are capable of meeting the operational demands of the Jind-Sonipat section.
Railways to run 35 Hydrogen trains
In a written reply to a Rajya Sabha question last year, Railways Minister Ashwini Vaishnav provided details about Indian Railways' plans for hydrogen trains. The Railway aims to deploy 35 hydrogen trains under the “Hydrogen for Heritage” initiative, with each train costing approximately Rs 80 crore and ground infrastructure at Rs 70 crore per route for heritage and hill routes.
Additionally, Indian Railways has launched a pilot project to retrofit existing Diesel Electric Multiple Unit (DEMU) rakes with hydrogen fuel cells. This project, including ground infrastructure, has been awarded at a cost of Rs 111.83 crore and is planned for the Jind–Sonipat section of Northern Railway.
While the initial operational costs of hydrogen fuel trains may be high, they are expected to decrease as more trains are introduced. Hydrogen fuel promises significant environmental benefits, supporting zero-carbon emission goals as a clean energy source.

What Is A Tilting Train And Why India's Getting 100 Of Them
India will get its first tilting train in the next two-three years, according to a senior official of Indian Railways. The technology enables trains to maneuver curves at increased speed, that too on regular tracks, just like a motorcycle on a winding road. Vande Bharat trains, manufactured in India, will be equipped with the technology by 2025 that will improve their speed. Such trains are now operational in 11 countries - Italy, Portugal, Slovenia, Finland, Russia, the Czech Republic, the UK, Switzerland, China, Germany and Romania.
"We will have tilting trains in the country. We will tie up with a technology partner for this. We will have this technology in 100 Vande Bharat trains over the next two to three years," news agency PTI quoted the Railways official as saying on Friday.
The Indian Railways has explored various options in the past regarding tilting trains, but has never finalised any detail. It also had discussions with Spanish manufacturer Talgo as well as the Switzerland government, PTI added.
How does a tilting train work?
When a train rounds a curve at speed, objects (and people) inside experience centrifugal force, which pushes them outwards.
The effect can cause luggage inside to slide, seated passengers to feel squashed and standing passengers to lose balance. These trains are designed to counteract the effect by tilting the carriages towards the inside of the curve, thus compensating the g-force.
According to Sweden-based KTH Engineering Sciences, there can be various mechanisms to neutralize the tilt force and achieve a balance. It further explains how motion sickness can be essentially eliminated by adjusting the timing of when the cars tilt.

Tilting trains are operational in 11 countries and an Indian Railways official said that Vande Bharat trains will also be equipped with this technology soon.www.ndtv.com
Actually, Speed constrain on Indian train is because of tracks and sharp curves rather than engine power. If we put proper track and manage curves, speed of all existing trains can also be increased. fencing, track quality and curve management can give capability to all existing trains.
Designed For 180 Kmph, Vande Bharat Trains Running At Average Speed Of 83 Kmph: RTI Reply
Vande Bharat Express, which is India's first semi-high speed train has been running at an average speed of much lower than 100 kilometre per hour (kmph)swarajyamag.com
Too conservative. It should run atleast 110 km on an average. Vande Bhart from A'bad to surat around 240 KM is managed in 2 hrs 10 minutes.
