Marker, please help me, I am about acquire a 3 rail version of the BL-109 and BL 110 set with passenger cars, I have converted other MTH items to 2 rail before, I would like to fix the pilot as you did and convert to 2 rail and add Kadees, I would appreciate any help you could give.
I think Dave C has done an excellent job of covering the couplers and the pilot. If you read my post, I was also looking for help. Regarding my pilot, I just drilled and tapped some holes and raised it. It is probably too high, as Dave C points out. I have a problem with getting spacers to look good.
Regarding 2 railing the engine, if you have done it before, I could use a tip. I do have an idea, but until I actually 2 rail the engine I think it's better for me to not comment. I wish MTH would start expanding their 2 rail diesel offerings. I'd love to see a PA, DL-109/110, and especially some switchers. (Actually it seems that Santa Fe had a DL-107/108.)
