Maintenance comes into play as well. Working on focusing a headlight on a dark night when it’s high mounted in front of a hot smokebox on a tall locomotive is not fun. There is only so much you can do while holding on with both feet and one hand while trying not to get burned when you can’t see what you are doing. On small engines, a high mounted headlight is still easy to reach while standing on the pilot deck. Not so on large standard gage engines.
