Although I find the prospect of an RTR 47 in 7mm very exciting, especially as it's set to cost less than a DJH kit, I'd be even happier if they'd do some rolling stock. Something like a 16 tonner and a 21T brake would be a sensible place to start (long lived and wide geographical spread), then maybe a TTA/B/V (a la Bachmann 00). I've emailed Heljan to suggest this, I hope they take note.
