One thing to remember with some of these locos like the GG1 from the passenger set is that it overheated.
There was a thread a while ago, about adding an additional resistor to help with the heat. I also recommend removing the white film strips that covered the windows. With all of the electronics stuffed into the loco, any fresh air that could make its way in helped the performance.

True very little air circulates around the GG1 E unit. I also found the power devices were not mounted securely to the heat sink. They only contacted it at the top edge. The original heat sink was a U shaped piece. I made a new one with 4 sides and mounted an additional heat sink to the top. In addition I put a small 12V DC fan next to it to help circulate the air.
