Thanks for the excellent info, Ray. Next trip to the hobby shop, I'll pick up these items. The Penn Line GG1, though a "shortie," was a fine loco for its time, and all metal, which you rarely see these days. It was nicely geared and out-pulled my buddy's 12-wheel drive Hobbytown E7. It was a Christmas present and I got the red one because the stores ran out of green ones. I was disappointed, but over the years have been glad that my dad got me a red GG1. I lived near the Trenton cut-off where we saw only green GG1s, but I saw red ones when we rode the train to New York. I'm in S scale now and recently purchased the American Models GG1 in green. It's a beautiful model, and scale length, but is missing some details, like ladders and handrails.
