The installation is for HO Scale Bachmann British 9F. It uses TCS M1P-SH decoder and was performed by Robert Lewis.
The locomotive is the Bachmann version of the British 9F heavy freight locomotive, one of the last designs to be built before diesels took over.
Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157 http://www.techni-tool.com
Picture 1 Remove the Pony truck by releasing screw no. 1, and then undo screws 2 & 3 to remove the body.

Other solder tips:
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
