When 14A came into the workshops for its last exam late in 2015, it was noted that one of the lens rings joining the main steam pipe from the header to the cylinder block was leaking.
One of the interesting ideas picked up on our tour of North Wales was the use of flexible steam pipes by the Ffestiniog & Welsh Highland Railway for carrying live steam and exhaust steam.
All that is required now is some rigorous testing to see how the flexible steam pipes perform, and whether the leaking lens ring issue has been solved.
