2. Diesel–electric powertrain - Wikipedia

   en.wikipedia.org/wiki/Diesel–electric_powertrain

   Diesel–electric transmission is similar to petrol–electric transmission, which is powered by petrol engines. Diesel–electric transmission is used on railways by diesel–electric locomotives and diesel–electric multiple units, as electric motors are able to supply full torque from 0 RPM. Diesel–electric systems are also used in marine ...

3. Voith turbo transmissions - Wikipedia

   en.wikipedia.org/wiki/Voith_turbo_transmissions

   In 1969, the smaller T 211 turbo-transmission was developed as an alternative to hydro-mechanical bus transmissions, being designed for diesel railcars in the low power range of 200 to 300 hp (149 to 224 kW). Similar to the first turbo-transmission, the T 211 used a linked converter-coupling combination but it also had a high-speed gear for ...

4. Hybrid train - Wikipedia

   en.wikipedia.org/wiki/Hybrid_train

   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 ...

5. Drivetrain - Wikipedia

   en.wikipedia.org/wiki/Drivetrain

   The powertrain consists of the prime mover (e.g. an internal combustion engine and/or one or more traction motors) and the drivetrain - all of the components that convert the prime mover's power into movement of the vehicle (e.g. the transmission, driveshafts, differential and axles); [4] [5] whereas the drivetrain does not include the power ...

6. Transmission (mechanical device) - Wikipedia

   en.wikipedia.org/wiki/Transmission_(mechanical...

   Transmission internals for a 2009 Volkswagen Golf. A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.

7. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by ...

9. Road switcher locomotive - Wikipedia

   en.wikipedia.org/wiki/Road_switcher_locomotive

   Within the Americas, road switchers are almost always diesel-electric, with the "transmission" system (i.e., the final drive) being either direct current (standard performance units) or alternating current (high performance units). For economic and performance reasons, 1,900 kW (2,500 hp) and lower units generally have a DC generator, producing ...
