Good for you. I guess, it depends on country and law.
Absolutely. I can't drive a train because of possible confusion between red and green signals but where I live the tram signals just use white bulbs.
Same here, about tram. I don't have problem about red and green lights. Or with colors when I wiring something. Just, I missed few points on eye test if I'm able to drive trains, tram and passed eye test that I can work on railway
