Small ideas can make Metro greater.

dynamic braking heat and light recovery

If energy from dynamic braking cannot convey to a nearby accelerating train, and needs to be drained from the third rail, use it to temporarily illuminate the station with bright halogen lights

These welcoming lights will signify the arriving train and be nicer than just heating the undercarriage. Simply connect blocks of lights in series to the third rail overvoltage control system.
