Simon Winter posted:If you're really interested in accuracy, you might want to seriously consider 2 rail. The BL-2s were made in phase 1 and phase 2 versions. The pilots were different, among other things. Bottom line depends on what road name you are interested in for the correct phase. Overland did some in brass a while back, and they were very nice. The BL stands for Branch Line. They are a very distinctive looking engine.

There was only one BL1 made, EMD 499, which became Chicago & Eastern Illinois 202. The only BL1 had no external differences from the BL2s. The differences were internal- an air operated throttle and no MU connections, so they were soon changed.
