I know most European companies build at least EMU shells that can be adapted to different gauges, as I've always assumed that the Red and Orange line cars are.
So, wondering about FTA vs FRA strength regs. Could you build a car that met both orgs requirements? Could CRRC shells be used to build EMUs, for instance?
So, my $15 Walmart space heater has a kill switch that turns off if the switch is not depressed. Having a hard time understanding why the cars could not have a simular switch to keep a door closed if the platform is not adjacent to it
