Ways to pass the time on the train

A Class 22000 DMU changes from first to second speed at this point. It never reaches third on this line because it never goes above 100 kmh.

I did that when I rode the Amtrak Auto Train in November. That one reaches 70 mph (110 km/h), which is not bad for what is essentially a freight train with passenger cars tacked on.

If it was me I'd have specified the transmission differently so it wouldn't spend nearly all the trip in first ( which uses a torque converter) rather than second and third (which use fluid couplings) but there you go.

It’s a relatively modern locomotive that isn’t pure electric or diesel-electric?

No wonder they were looking for ways to improve the fuel economy .

No, it’s a DMU as so:

Only a small number of our trains are loco hauled. DMUs are rarely diesel electric, it's heavy, expensive and inefficient.

From your provided link:

An additional nine cars are to be fitted with a diesel-battery hybrid MTU / Rolls Royce power pack as a trial [9] , with route-dependent fuel savings of up to 33% [10]

Yes, I’m aware of that, but it’s not diesel electric in the usual sense of the term . The MTU system is like the setup that BMW and Merc use so you have a motor/generator sandwiched between the engine and a conventional automatic gearbox. When braking the motor/generator recovers energy which is stored in a bat tery pack and used for starting the train and assisting the engine. At no time does the engine drive the train electrically - power always flows though the gearbox.
