A while back I acquired a Hornby Class 50. It caused a dead short on DCC. It got put on the 'Locos needing attention' shelf, and promptly ignored for a few months.

Accurascale then announced a Class 50 -- but skipped this specific variant (TOPS pre-refurb) in their announcement. So I decided to see what was wrong with this one, and if it could be fixed...

There's a lot of pointless stuff on the circuit board which is not necessary with DCC, so I went through it, worked out what it was for, what was causing the problem, and what I could safely remove. I then worked out a way to make it work in DCC -- it only needed a couple of wires adding.

I still need to get a set of headcode lights for it though...
