Couple months ago took the little ones to the train museum in Sacramento, CA (very awesome place, with an enormous cab-forward inside). http://www.csrmf.org/default.asp
Outside of the turntable & roundhouse (behind camera in the picts below) is a 3-way stub switch leading to the car barn. In Model Railroad Hobbyist there is an article about building stub switches http://model-railroad-hobbyist.com/ so thought I’d post the prototype pict for any interested.
The humans inserted for scale are 33" tall.
The one I modeled (in 1:1 scale) is on the left.
Cheers!
