Specifically, the number of energy storage tender cars determines a train''s payload, i.e., the number of revenue cars. The rate at which energy storage tender cars displace revenue cars is a function of technical elements such as freight characteristics, locomotive power, topography, travel speed, and track geometry and condition.
A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source (often a diesel engine prime mover) and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
