I've got three more loco's fitted with decoders...

Hornby 28xx

Mainline Pannier

Bachmann Pannier

I have to say, the mainline split chassis are far easier than I thought they would be. they are a pain due to the fact that they have to be pretty much totally dismantled in order to fit a decoder, but they are not at all difficult in the least. In fact, I've figured out a way to wire them up without a drop of solder!
