A woodford opinion, you have been warned.........................
The problem appears to be a steamer is a VERY expensive machine to run and is beyond most individuals/small groups ability to run. Even the A! locomotive trust after they completed "Tornado" kept the fund raising going to pay for future boiler repairs. Its likely the best that we can hope for is the same thing that was apparently done for the "Mallard" or the "City of Truro (Note 1)" (both famous steamers) these were repaired and run for a period then put into museums before any serious boiler work was required. Even the management at "Puffing Billy" has to work hard to make sure enough funds are around to keep there 5 36 ton NA's and the 65 ton G42 garrat going
Note 1: The "City of Truro" was retired because it was found on an inspection of the boiler for a leaking tube that the boiler required some serious work, it had been announced though after its restoration that it would be run for a time then placed in a museum.
Note 2: Both the "Mallard" and the "City of Truro" are regarded as VERY valuable locomotives and they appear to b regarded as to valuable to risk.
Note 3: Just in case anyone is wondering, the "City of Truro" is the first steamer proven to have reached 100mph (in 1904) and the "Mallard" holds the maximum speed record for steamers (126mph).
