Referring to train braking isn't that helpful - sure, powered units may
have dynamic braking, but that's not enough for the rest of the train.

Sometimes but not always remember the underground have used this for a
very long time now as do some of the more modern EMU units..


Well exactly. Train brakes are pretty crap by and large.

Due to the actual brake system or the steel wheel on steel rails?...
