Following on from the interesting discussions about potential new diesels for the F&WHR (https://national-preservation.com/threads/welsh-highland-garratts.1417373/), I decided it might be worth starting a dedicated thread on the subject. Obviously new-build diesels cannot strictly be considered "preserved" but they can play a role in keeping heritage railways running, so I think they are relevant on NatPres Anyhow - what prompted this thread was that I have only just learned that the Durango & Silverton Railroad in the USA has apparently ordered two new diesels (https://trn.trains.com/news/news-wi...two-narrow-gauge-diesel-from-south-carolina-1). They were due for delivery earlier this year but I haven't been able to find any photographs of them so I assume they have not yet arrived. The really interesting bit, though, is that they are being built by Motive Power & Equipment Solutions of South Carolina...the same firm which gave us the much-maligned Isle of Man Railway No. 21. It will be interesting to see whether the Durango diesels can avoid the problems which have beset the latter!
