GEC's Layout Progress

[ac_catenary]

While the basic dimensions were the same (catenary height, cross-beam height, sag brace locations and height), the transmission and signal arms were both larger and spread farther apart than suggested in many of the catenary articles i've read, such as Andy Rubbo's three part series in the Keystone modeler. For example, the PRR document says that the transmission arms should be 18 feet across, while i think it is 13 feet in the Rubbo article. I wonder if it is because we often view the catenary from the ground, and not up close, appearing smaller, making the 13' distance appear more correct.

I have the dimension PRR Standards got them from the ET department at work and I know I must have shared them with you. They are on the PRR electrics Yahoo Group and I recently gave a guy permission to put them on his site. That is why my transmission arms are bigger than Rubbos and Yours
