The Bachmann Fairburn 4MT Tank engine is a favourite performer here at locoyard. It predates this blog, so a DCC fitting guide was never published before, however as the locomotive had a small decoder fitted but had space for a bigger one, I took the opportunity to replace it and publish this guide!This is a reasonably simple procedure. As usual, you want to be sure the model is running well with no problems in DC first.
Even a large DCC decoder will fit in the smokebox of the body (see above). However, the motor mechanism behind the 8 pin socket is exposed. So be careful that no wires are trapped above it – you may find a little insulating tape is needed to help tidy the wires. Test that it works and re-screw the body to the chassis and you’re done. A simple job!
