Wow, I had no idea they existed, single chain as well so must have been reliable.

you actually had quite a lot of them in your area, MSCC (Manchester ship canal company) used Sentinal's that were chain driven around the canal all the way from Ellesmere Port up to Birkenhead

Withdrawn just before my time, fascinating to read the specs though https://www.lner.info/locos/Y/y1y3.php

we had some locos that could generate up to 8500 amps for initial pick up from a standing start


That is a whopper of a bang when that goes wrong

The reason for DC is that DC motors have a much higher starting torque than conventional AC motors.

The other factor is that an AC motor speed is governed by the AC frequency, so the speed of the generation system governs the speed of the motor and you'd lose the torque convertor effect of using DC where you wind up the diesel engine revs to create maximum power, this would just create a stall on an AC system.
