Which locomotive has received the most overhauls since BR days?

Having just read on this forum that 6024's next overhaul is to start soon, I am asking what locomotive has received the most 7 or 10 year overhauls, since BR days?

I believe this latest overhaul will be the fourth for 6024.

60103/4472 must have had a few.

 

Stepney? I don't know how many overhauls she has had, but there haven't been too many years in the last 52 when she has not been running. (Or, in fact, too many years in the last 137

Mind you, at the next overhaul she'll only need new frames, wheels, cylinders, boiler, tanks, motion and a few smaller components ...

The Great Marquess (3442/61994) has to be up there too i'd imagine. It was preserved relatively early and has been a runner for the majority of the time since.

 

45407?

61994 had a long time out with problems with its crank axle in the late 1990s and early 2000s. I can remember it at Bridgnorth.

 

62005 certainly holds the record for the most number of re-tyrings, and it has run pretty well continuously since 1974. 45428 is another that has done a lot of work but has had one or two lengthy spells out of traffic. On the SVR, 46443 seems to have been ever-present.

 

Clan Line?

 

What about 60009?

 

Would 60007 be far behind ?

 

5690, 4472, 3205 come to my mind.

 

Probably not quite what the OP had in mind when asking the question, but Tal-y-llyn Railway number 4 (Ex Corris, GWR and BR) must be a contender - overhauled in 1951 or 52, it seems to have been returned to traffic regularly since then.

If we are to restrict this to 'full' overhaul, presume this to mean every 10 years and boiler lift, not just fettles. Then if a loco had its last one in (say) 1967 the last year of steam overhauls, 4 x 10 year overhauls would take us to 2007. So not many, if any will have had more than 4 full jobs since preservation, perhaps just on its 5th now.
You should be looking for a loco that didn't go to Barry, withdrawn from service and continued ever since. This should narrow the field.
I'm not a betting man, but I would agree 45407 could well be a contender.

 

Anybody any idea how the current overhaul is coming along??

 

That theory does not work when locomotives don't have 10 year boiler certificates. No locomotive is guaranteed for such a long time. Last time i asked a boiler 'ticket' was given for only 14 months at a time and no longer. I would think this is probably still the case?

 

I would have thought 4472, 35028 and 92203 have had a quite few since they went straight into preservation. Also 45407 must have clocked up a fair amount........

 

This is. called an annual boiler exam.

 

I was under the impression that the rules state that a main line certified loco should be overhauled every seven years and a loco running on a heritage line every ten years. The boiler insurance certificate is renewed every year (14 months) provided everything is found to be OK by the boiler inspector.

 

The procedure on the railway was - maximum 5 years between full internal exams.

Boilers had to be examined at fixed intervals. The actual interval depending on the work they were doing, but it was a maximum of a year in any case.

This could be extended by a boiler inspector at his discretion in six month stages up to an absolute maximum of 7 years. This was a very rare occurrence though, and the inspector knew that their head would be on the block if they got it wrong. Very few engines got past 5 years, and out of the main line engines i.e. not shunting, I only know of one so far that reached 7.
