This installation of TCS EU621 Decoder is for HO Scale Bachmann model of the English Electric Deltic locomotive and was performed by Robert Lewis, UK.
This is a Bachmann model of the English Electric Deltic locomotive, commissioned as a limited edition by the National Railway Museum in York. The original locomotive built in 1955 has two 18 cylinder engines with the cylinders arranged in a triangular formation, generating a total of 3,300 hp, the most powerful single-unit diesel in the world at the time. It was known as DP1, although it never carried a running number, just the name "Deltic".
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
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.
