I bought a EMD GP40 locomotive, Santa Fe DCC equipped. I want to remove the shell, but am not quite sure how to do so without damaging anything. The diagram that came with the loco. doesn't help very much. Can someone tell me how to remove the shell?
Thanks

 I'm trying to lay down a WYE using e-z tracks. I can't figure out which tracks to use. Could someone please help with which tracks to use so that everything fits in place?
Thanks for the help
