Guys,
I have always liked the look of the small diesel yard goats. (When I was a kid, we called them yard runners.)
But, they are so short, and I'm guessing that they only have one roller, or maybe two that are really close together.
Given this, how can they operate smoothly when they are crossing all of the switches and cross tracks in a yard? Don't they sputter, stall, hesitate and balk? If so, how can they be of any use in a yard? And, Lord Forbid, what happens when you stop one on a switch?
Thanks for any information.
