After the WSR's updates (following the new Thomas addon), I think its time we get a new diesel-hydraulic engine. The Class 35s are a great example of this. Two of them live on the WSR, and could substitute for the 52, 33, and the 47. Comes with: BR Class 35s D7017 and D7018 MK1 BSO MK1 TSO MK1 FO MK1 SO GWR "Toad" Breakvan Routes it could be layered: West Somerset Railway Great Western Express
Long overdue and much needed. My money is ready. I believe 4 of them still exist including 7017 and 7018 at WSR. Plenty of opportunities for reference visits. The Hymeks are perfect for WSR and DLoGW. Whilst on the subject of diesel hydraulic locomotives, Class 42 Warships Greyhound and Onslaught are still around as well. With a little extra effort, the Class 43 Warships might also be possible to create as they are just equipped with different engines and transmissions. Yes please to the Hymeks.
It would be nice to have another of the home loco's to the WSR as it's kinda boring seeing a 52 and 33 which isn't realistic at the moment
