As we were discussing in another thread, the distance between the rails is usually much less than the width of the locomotive. The space between the drive wheels is smaller still.

If you click on the 2nd of the links Bert Nobbins posted, you'll see another solution: the boiler is on a separate chassis from the pistons and drive wheels. This solves the issue of the locomotive being too tall, but you end up with much less weight on the drive wheels, which means inadequate traction.
