So the interval between the low and the high horn on the 377, and I believe the 387, is the same interval as the opening of Oh Canada. Out of curiosity is this… a) a British rail regulation on horn sounds? b) a Bombardier thing because they’re Canadian? c) a coincidence?
It'll be a co-incidence. You shouldn't be using the high tone anyway except in an emergency (IIRC that reg was brought in in 2007). I doubt that interval is really there on the real units, and it's more to do with the game.
