This installation really is very straightforward as the engine is DCC ready. The most difficult part of this installation was actually removing the screws attaching the body to the chassis. Although the screws could be turned, they would not drop out and the body could not be removed. This particular loco was returned to Bachmann to have the screws removed. Before installing chip into any loco it is advisable to check the current being drawn by the loco. |

The body is secured to the chassis with 8 screws, 4 located around each bogie.

The loco is DCC ready, having a socket installed in the middle of the loco. Gently lever the dummy plug out of the socket. This installation used a TCS MC2 UK decoder, one of the smallest decoders on the market, with a short harness for UK locos. It is also advisable to disable the capacitor on the circuit board by cutting through one of the legs securing the capacitor to the circuit board with a pair of wire cutters. This action is recommended to improve the performance of the loco with a decoder installed, but be aware that disabling the capacitor may invalidate your warranty. |
 |
Firmly push the plug attached to the decoder into the socket, being careful not to bend the pins. Make sure the decoder is correctly orientated, with the orange wire at the front left at Pin 1, clearly marked on the board. It was also necessary to cut the legs of the capacitors each side of the motor on this model to improve the running. It is suggested that you do any programming of the decoder, before replacing the body.
