For anyone who doesn't know, this is what the mystic thermic siphons in the boilers of Bulleid pacifics look like
Another full scale loco kit today, the cabside of Blackmoor Vale, which was in for some routine tinkering, as well as a bit of unscheduled firebox stay replacement
For anyone who doesn't know, this is what the mystic thermic siphons in the boilers
of Bulleid pacifics look like
The idea was that they helped circulate water through the boiler and increase the
steam raising capacity. Their effectiveness has always been a much debated
subject!
This is what happens to the cab should you need to get at the some of the stays in a hurry. To remove the
cab in one piece would have taken too long given the curren traffic requirements, and judging by the marks
on the surrounding metalwork, BR also took the same view!
