Alan is correct about low volume with MRC. I also used a TP baffle and it does help. I have my original MRC instruction sheet. It tells how to set board to different prime mover sounds as well as a variety of horns, {with out the remote}. Just using a transformer with horn and bell controls. However the remote makes it easier. They are all quite different. Alco 244 is the first one listed available. I can't get my scanner to work, but I'll be glad to mail you a copy if you want. Let me know.
