Two way AC DC converters come in all sizes.
There is a big one at Folkestone.

DC regenerative brush motor systems are common on mobility scooters.
I sometimes go round the flea market in the company of a mate on a scooter.
It is a small one that can be taken down for loading into a car.
It climbs up the hill from the parking to the cobbled market with three LEDs of power still showing and goes down to one LED after going round the cobble stoned market square and then back up to three LEDs after going back down to the hill to the parking.
Trams and trains with overhead electrics use an on the fly system most likely with a brush-less motor.
They use a more exotic converter that creates variable AC from fixed AC in drive and the other way round during braking.
