BNSF leads the charge on testing battery-electric locomotive
Before the pilot testing of the locomotive can begin, a battery charger will need to be designed and installed at BNSF''s Mormon Yard in Stockton later this year. While the Stockton battery charging station will provide an initial charge, the new locomotive will be designed to provide regenerative power under braking to extend its range.

Energy management strategy to optimise regenerative braking in a hybrid dual‐mode locomotive
Embedded energy storage sources such as SCs or batteries are used to perform recovery braking. They are a more viable alternative to recover energy during braking. This option is similar to the one used in an application with a high-start/stop frequency such as elevators driven by synchronous machines [ 36, 37 ].

Regenerative braking in trains | Climate Technology Centre
It is possible to use regenerative braking on these high speed trains because most cars have their own electric motors, this is in contrast to trains in which only the locomotive has electric motors. The fourth generation TGVs in France, which are expected to be commissioned in 2010, will also be equipped with regenerative brakes, as will the …

Application of flywheel energy storage for heavy haul locomotives
The flywheel system is designed to become fully loaded before the dynamic brake resistors start. The interconnection of the A and B units allows the flywheel access to the braking effort of all of the locomotives. In this configuration, the primary role of the flywheel is to recover braking energy. 3.3.
