This paper reviews the application of energy storage devices used in railway systems for increasing the effectiveness of regenerative brakes. Three main storage devices are reviewed in this paper: batteries, supercapacitors and flywheels. Furthermore, two main challenges in application of energy storage systems are briefly discussed.
Abstract: The braking energy in diesel-electric locomotives is typically wasted into resistors. A more energy-efficient way is to store and recycle such energy.
Operation modes of rolling stock at mining enterprises are considered and analyzed. The justification of the need to replace it with a modern specialized electric locomotive for quarry railway transport, equipped with an asynchronous traction electric drive and an on-board energy storage system, is presented. The determination of the
Comparison of locomotive energy storage systems for heavy-haul operation This paper modelled flywheel and battery energy storage systems for heavy-haul locomotives. Three heavy-haul trains with their traction power provided by diesel, diesel-flywheel, and diesel-battery locomotive consists were simulated on an existing railway.
In Shanxi, China, a hydrogen locomotive was unveiled in 2023 which can run for up to 190 h with a 270 kg liquid hydrogen storage on board, and it will take two hours to refuel the hydrogen storage. To increase hydrogen storage safety, this locomotive has a fireproof wall to separate hydrogen storage from fuel cells and a ventilation system that

A novel design for heavy haul locomotive equipped with a flywheel energy storage system is proposed. •. The integrated intelligent traction control system was developed. •. A flywheel energy storage system has been tested through a simulation process. •. The developed hybrid system was verified using an existing heavy haul
Energy storages for the flywheel and battery ESSs are 500 kWh and 5000 kWh, respectively. Traction performance, fuel consumption, and emissions were compared for the three simulated trains. The results show that, compared with the diesel train, the diesel-flywheel and diesel-battery trains were 13.26% and 9.20% slower in speed, respectively.
VANCOUVER, BRITISH COLUMBIA – September 1, 2021 – Loop Energy (), a developer and manufacturer of hydrogen fuel cell-based solutions, and Hydrogen In Motion (H2M), a leading provider of solid state hydrogen storage, announce their plans to collaborate on converting a Southern Railway of BC owned and operated diesel electric
This paper studies the influence of an energy storage system (ESS) on the fuel consumption of a diesel-electric locomotive.

Liu et al. [ 45] calculated the energy density of compressed air to be 370 kJ/kg under the storage pressure of 20 MPa, which is much lower than that of diesel or gasoline. To ensure the continuous supply of compressed air during the operation, the power of the engine or the vehicle speed must be limited.
