will the EL Fa & Fb shells (11241 & 11239) fit on dcc units ie 60135 erie F?
The Erie Lackawanna shells are an F7A and F7B while the Erie is a FT-A and FT-B. The shells will transfer, but not without doing some work first and they won't be a perfect fit and the wheelbase will be the incorrect length. Once you switch the shells, you will not be able to switch back because components that you need to remove from the one shell are necessary for the original. You will need to cut off 2 of the screw holes, they are long plastic stems, once you remove these you can't, put the shell back on its original loco.
