Ken,
The way rail is moved on flat cars and the narrow ROW, there is no real access for a loader. We do have rail tongs, but it is actually easier with 60# rail to use 6-8 people per length. When rail is slid into place for spiking, we do use tongs. There is not much that can be mechanized and besides, except for mules and horses, we do it in the early 1900's style.
We loaded 20+ tons of rail Saturday and used no mechanical assistance, just manpower and brains plus some oil.
I hope this explains how we do this a little better.
