I have a Williams scale GG1 number 4876 ( the one that pulled the Federal and crashed through Union Station in January 1953 ). I also have a scale Williams dummy GG1. I like running them in tandem. As others have said , the overhang on 042 is pretty ridiculous. I have 042 curves at one end of my layout and 054 at the other end. I also have created tunnels at each end of the layout which hide any ridiculous looking overhang of the GG1 and other scale locomotives with excessive overhang. The Williams scale GG1 is a great puller and is problem free mechanically speaking. I've had mine since 2008 with no problems so far. I'd say buy one Foxer55!
