There are no pictures to show here, but just to say that I've recently converted Old Parrock to DCC. I've bought a NCE Starter Pack which seems perfect for the job. Electrically the conversion was straightforward. I beefed up the main circuit a bit and fitted the little control panel on the front. It all went very smoothly. I've decided to have sound as well so converting my five locos is having to happen at 'saving up' intervals.
My reason for doing this was that I just wasn't achieving the smooth starts and stops that I crave. There's no doubt that it is a lot better with DCC. The first loco I converted, the Bachmann SECR C Class runs astonishingly well with DCC - such fun to play with.
Now to the Rails of Sheffield Dapol terriers. They're an absolute pain! So far I've worked on one of them. In order to get the running up to scratch I had to add my own supplementary pick ups, which I achieved on two sets of wheels, and open out the coupling rods (not too much luckily) which suggests poor quartering. The centre wheels still lurch. Getting the decoder and speaker in place was extremely difficult and hazardous. To anyone else attempting this, it's vital that the speaker connections are completely insulated because if you just put the body on without precautions they short against the motor frame, which I found out to my cost. I painted the connections with shellac and also covered them with kapton tape. Unfortunately I couldn't fit a stay alive capacitor so there is still the possibility of the occasional sudden stop (which I hate with a vengeance!).
More anon.
