Thanks Stephen, unsure on the DCC question, there's a protected simplex in 009 on ebay at the minute, though that's on a old chassis by the looks of things. AFAIK there isn't another available in 009 but the kit does go together really well, it's an easy build and the Tomytec motor is a good runner. The 009 Simplex's that are 3D printed are great but you need to be able to add weight and find a chassis small enough to accept the body and additional weight, which is where I've somewhat failed with mine.
Best of luck with the building of your layout!
