Re: Rubber switches

I'm guessing we would have called spring switchs rubber as well, but I can't remember any spring switches in the areas I worked in. But the San Francisco and Bayshore yard was full of the variables, mostly if not all low level and marked with the little yellow square sign with a black V.

Kinda as a nostalgic aside, I don't remember any spring switches. But I'm going back in the 60's when we still had cabooses. Would guess that the big impetus for spring switches was when cabooses were taken off and there was no longer a rear end crew to line behind a train. Now spring switches are all over the place.
