Quite fancy one of these ,just to collect,maybe the first version in gloss black ,the thing about pre ordering things like this is it takes around 18 months before you receive it ,if your lucky ,I've had the NER autocoach ( rails exclusive ) on pre order since this time last year and it is due to be in stock towards the end of the Q1 2020.

I have a major curiosity about how this one is 'made to work' for RTR OO. The deep and very visible full length frame (in the fetching lilac colour) is narrower than the body work, and fully encloses the tops of the large bogie wheels. That's going to be a challenge for the standard R2 capability, there simply isn't much side to side clearance for the bogies to swing for curves. It will be a question of which of the various dodges available the designer goes for (over scale frame width, undersize wheelsets, increase ride height, make frame non continuous and allow the section surrounding the wheels to move with the bogie).

I saw the thing just once, waiting on a bus (front top deck) at the single lane bridge that crossed the end of Bescot yard, this thing came through pulling a long rake of decrepit bogie vans. Took me ages to find out what it was. The rake of vans must have been a set kept by Swindon, because I'm sure it was the same set I saw behind one of the first Westerns. The route through Bescot, Aston and the South Birmingham line was a diversion which avoided Snow Hill and regained WR metals at Tyseley.

For those that don't know, the reason for trying a gas turbine was relatively cheap fuel. This was 'Bunker Oil' that was the residue from petroleum refining at the time. In one form or another this delightful goop had proved useable in steam locomotives; and here was an alternative technology that might be a way of using it, with the added bonus of no significant water supply requirement.

What those concerned could not foresee was the rapid development in refinery technique, and particularly the 'catalytic cracking' that would soon emerge, which meant that the available volume of the cheap residue product declined dramatically. As it was, the gas turbine tech. wasn't 'all there yet' and the railway operating environment wasn't favourable to its most efficient use either. So diesel it was to be. Of course, current small gas turbines are easily an order of magnitude superior. It might not be over...
