An overhaul is scheduled and plans can be made for an another suitable engine to deputise, in 2015/17 it was Tornado. The current problems with the Syphons was unforeseen and it’s unfortunate that no other DB registered loco is available. The intermediate overhaul taking place at the same time was scheduled for this time of year when the loco is normally stopped for winter maintenance. It would probably take just as long to change a boiler than do the work currently being undertaken. The intermediate overhaul extends the mainline certification to 10 years. If you want to know more of what’s involved, join the society and join us at Stewart’s Lane, I’m sure you will be made very welcome.
