This is my first attempt at DCC Loco conversion, hope this is of interest.

After reading many related threads on the forum, I decided to try out the TCS T1 decoder for the following reasons. It is good value for money, is a reasonably compact package, has good spec and is well recommended.
Converting this Loco was very enjoyable, the Bachmann PCB is discarded and it's metal mounting posts need to be sawn or cut off, then filed flat. Although hidden by the outer shell, I decided to paint this new surface black to keep things tidy. The TCS decoder is a perfect fit, I secured it with two sticky pads.

I havn't decided if I will fit lights to this model yet, but I wanted to test the forward & reverse lighting function as this is the first loco I've converted. Hence the basic test LED arrangement seen in the photo. For the time being, I've resisted the temptation to trim any of the wires just incase.

The problem is........my DCC system is yet to arrive, so I can't try it! With a bit of luck, all will be well.

I tried the body fit before rigging up the LED's and it fitted OK, not much room for anything else though.

M1 & MC2 both look a good choice for small spaces, cost is up slightly however.

Simon, Thanks for your interest and kind words. Resistor values quoted by various sources seem quite conflicting. I have read that 1K ohm 0.25Watt resistors are a good value to start with, and I've fitted these as a starting point prior to testing. There is a good PDF guide titled "Simply Programming" for download from TCS (Train Control Systems) TCSDCC.com. This includes a table for resistor selection with both bulbs and LED's.
Probably best to get a selection of resistors to try until you acheive a desired brightness. e.g. 1K Ohm, 680 Ohm, 470 Ohm. Try Rapid Electronics, they sell packs of 100 same value resistors reasonably priced. Rapid Electronics.
After my 50th DCC conversion, I'll probably be a nervous wreck! My next project is a Bachmann GWR 57xx split chassis, and that to put it mildly, looks like fun.
