Thanks Rich, isolating the motor is no probs, done a few already on old locos. I think I might use an N scale Chip, as they are much smaller physically, and i image the motor will have only a very small current draw. And yep, looks like it goes in the bed, and covered with a load. Appreciate the info TREV

Hi,
living here  in Australia, I have been unable to see, touch, hold the Bachmann Hi Rail pick up truck.
Can anyone tell me if it has enough room to fit a dcc decoder into it, or even if this is possible.
Thanks TREV

HO in the garden has a few issues you need to consider during the planning stage, but is very achievable. I run HO outside here in Australia, using DCC for control, and all my locos are fitted with sound decoders.
There are obviously some things to do differently compared with an indoor layout, but nevertheless HO can be very successful outdoors. England has a vast number of outdoor HO layouts, and a reasonably deep crawl of the internet will find a lot of valuable info.
Don't let the doubters put you off. If you want to run long trains on wide curves, then the garden has plenty of room for this. All the arguments for N scale basement sized layouts apply to HO outside. There is nothing better (in my opinion) than watching a double or triple headed consist pulling a 30-40 car train through a 60 inch radius curve and then heading into the distance.
