"Great Bear"


gibbooo

Recommended Posts

The 'Great Bear' was basically a 'Star' with a big boiler and firebox and some extra wheels to accommodate it. It seems that there were plenty of 'teething troubles' and by 1924 it was decided to rebuild it to a 'Castle' class No. 111 'Viscount Churchill'.

 

As a 'Castle' it lasted until 1953.

Rebuild as in scrap most of it and incorporate the remaining pieces into a new Castle with the number carried by Great Bear?? I think you might find it was the first Castle to be scrapped although I'm open to correction.

 

Rather like the LMS

 

Patriots 45502-45541, they were called 'Renewals' of Claughtons although there was no Claughton in them. Even 45500 & 45501 had very few Claughton parts in them, although they were called 'Rebuilds'. Same with the Royal Scots - new boiler, cylinders, renders,

 

not a lot of Fowler left there!!

It seems it followed a similar rebuild to the handful of 'Stars' that were converted to 'Castles', with perhaps a lot less of the original reused.

 

A similar course was followed by the Southern which built H15 class 4-6-0s nominally out of a variety

 

of deadbeat LSWR classes. And then there were of course the LNER P2s.

Which leads onto the remark Churchward make to Collett, when he hear about the then Mr Gresleys' new Pacific 1470 Great Northern. "Why did that young man build than for, "We" could have sold him "Ours"? Which in turn just goes to prove that, Gresley Was

 

Right!!!!!!!

Hi LC&DR

 

The P2 rebuilds were more of a rebuild than the Patriots or Great Bear. The original boilers were retained along with the cab. The mainframes were reused (with a new front end welded on) and the coupling and connecting rods were carried

 

by the rebuilt engines.

 

There was severe frame weakness after rebuilding, in the area around the cylinders. They were also very heavy on maintenance, in particular the cylinders becoming loose.

 

They might not have been perfect as P2s but they

 

were worse as A2s

In my opinion the Thompson P2 rebuilds as A2 were some of the ugliest locomotives ever to come out of a LNER workshop. By contrast the Peppercorn A2s were handsome beasts.
