After the success of the plandampf on the Settle and Carlisle line using 60103 “Tornado”, what other routes would be good candidates for something similar?

For the uninitiated, plandampf is a German word describing steam locomotives taking over regular scheduled services for a few days or a weekend rather than the more usual one-off special that doesn’t appear in the public timetable. It’s been a popular thing in Germany for many years.

Here are a few suggestions; since steam locomotives are restricted to 75mph on the main lines it rules out inter-city routes, much as we’d love to see a King running from Paddington to Plymouth instead of a High Speed Train.

The Conwy Valley line

This spectacularly scenic line is one of Wales’ best-kept secrets, the one surviving standard-gauge line to run into the mountainous heart of Snowdonia, and also connects with the narrow-gauge Ffestiniog railway. As an operationally self-contained line, it’s ideal, and the current timetable allows a single train to operate the entire service, though a second locomotive might be needed to speed up the turn-round at Llandudno. The passing loop at Llanrwst North would also allow two-train operation for a more intensive service.

The Central Wales line

This is much longer scenic trip from Swansea to Shrewsbury over a meandering route through the hills of mid-Wales that allegedly only survived the Beeching cuts because it ran through so many marginal parliamentary constituencies. It has the advantage that there’s a triangle to turn the locomotive at both ends of the line, so no tender-first running over the most scenic part of the route The one potential problem is the reversal at Llanelli, though top-and-tail working with a diesel for the short section between Swansea and Llanelli might be one solution here.

Par to Newquay

This is another of those scenic Cinderella lines that, like the Conwy Valley, is crying out for some heritage traction. Lack of any run-round facilities at the Newquay end means top-and-tail working will be necessary, but it will likely need two locomotives to keep to time on those grades in any case; back in the steam days holiday trains needed banking on the 1 in 37 up the Luxulyan valley. A train with a Castle or Hall at the front and a 52XX 2-8-0T at the back would something to see slogging up that grade.

The Greenford Loop

For something completely different, how about this short and self-contained shuttle from West Ealing to Greenford in west London? Rather than a day out behind a big main-line locomotive this is ideal for a Great Western auto-train and the recently-restored steam railcar. The line is double track, so there’s the opportunity have two trains running at the same time.

Over to you. What lines would you love to see taken over by heritage traction for a day or three?
