Fast train acceleration

Yeah our commuter train Frontrunner is a push pull.

Reminds me of Danish push-pull trains before electrification. The Danish GM-powered diesel locos seemed to have only 2 throttle position: on and off.

Mentira. Vídeo de trás pra frente.
Lie. Movie backwards.

The movie is not backwards, that's why the headlights are on the front and red tail lights on the back, and why the exhaust trails the train. You can also see the LE's seat on the right hand side of the locomotive at the back, is empty (and there is a car in the car park driving forward). This is a push-pull train, so the loco is at the rear half the time.

Dang!. pretty fast for a diesel engine. lol.

is this in new zealand?

true apart from in germany where a lot of diesel hydraulics r/ were used, these either have multiple torque convertors (different ones for different speeds-dont ask!) or torque convertors and gearboxes.

All trains are electric. The key is the source of the electricity. All trains run on electric traction motors. Either power from supply line or power from the diesel powered generator. Difference is weight. All electric can't pull the same weight over distance. Turbo motors are replacing diesel. They are already making them in Eire Pa.

Not all are electric, there are also diesel-mechanical and diesel-hydraulic locomotives, in addition to diesel-electric.

Ours are diesel mechanical. Type in Class 159 leaving clapham in the search box. Cummins 350hp or 400hp engine and Voith Hydraulic transmission. Strangely the 350hp versions are quicker than the 400hp for some reason.
