Hi Roly,
I'm pretty sure mine's got an XL in it - I'll have to check my notes. From memory, I think it was a case of removing 4 screws to remove the bunker behind the cab, then I think I simply disconnected certain wires from screw terminals on the Bachmann board and re-wired them to the appropriate terminals on the XL. I've got a vague memory that I may have sited the decoder beneath the Bachmann board. It certainly wasn't a difficult install so nothing stuck in my memory as being a problem!

PS: The Mikado's running nicely - it now has a new smoke unit from Cornwall Model Boats! Damned if I can get it to respond to a long address on my NCE system, even though the decoder seems to accept the programming and returns a long address when queried by my SPROG and JMRI. Must be a decoder version that's too old. No problem, short address is fine! Seem to remember my LGB mogul with a 55021 decoder is the same.
