Hi,
You can get a preview every 2 weeks of whats next on this site/link http://www.greatbritishlocomotive.co.uk/the-models/
The original list seem to go off course a couple of issues ago so we now seem to be in "pot luck land" but once the latest one is released they do seem to add the next one more or less the same day so you can see whats coming up next.
EDIT :-
Checking the 'original' List this is how it should have been
Original Delivered
1. Mallard 1. Mallard A4
2. Coronation 2 Coronation
3. Flying Scotsman 3. Flying Scotsman A3
4. 28xx 4. 28xx
5. Stowe 'Schools’ Class 5. Stowe Schools Class
6. ‘Deltics’ 6. Evening Star
7. Evening Star 7. Deltic
8. No. 44781 ‘Black Five' 8 Black Five
9. City of Truro
10. Gresley ‘K3’
11. Bulleid ‘West Country’ unrebuilt
12. Fowler 3F ‘Jinty’
13. Collett ‘Castle’
14. No. 1000 ‘Compound'
15. BR standard ‘4MT’ tank
16. Locomotion
17. Sulzer ‘Peaks’
18. Butler Henderson
19. 45xx
20. 'T9’
So it only went out issues 6 and 7 so hopefully were back on track with the original List ...
Cheers
Steve
