I recently came across this thread which didn't surprise me however I would like to add my thoughts.Austerity class locomotives are like other industrial locomotives, are underrated and little respected by the average railway enthusiast because simply they aren't mainline express engines which is a great shame. As said in earlier replies, an industrial steam loco is better than a diesel.
Unfortuanatley I grew up after the steam era and as much as I like old blue British Rail diesels such as class 47s, 37s, DMUs and class 20s steam has the edge!
I don't think people flock to heritage railways to see old diesel trains, Ok there are diesel locomtive fans but for a heritage railway to survive they need steeam! Unfortunatley there simply aren't enough
of them in the country and that's including industrial engines.It takes a long time to build a new one and as long if not longer to rebuild/overhaul an old one.
A volunteer at the SVR said to me that the SVR needed ten operational steam locomotives for full strength, how's that determined? Are there any heritage railways running at full strength?
When I visit a heritage railway I like to see a variety of locomotives in use and I guess other people do as well?
There are some heritage railways that don't have any at all which surely is a disadvantage.
My interest in railways is mainly GWR branch lines and Welsh narrow gauge but after visting the Foxfield Railway and Churnet Valley I now can appreciate industrial steam locomotives whatever they look like.
I think their looks could be improved with Swindonisation.
