Take a look at this Ebay image :-

Was it some form of insulation trials?

( NOTE not my image )

 Having now trawled thru Google for 44756 it seems to have been like that for some years - take a look at

  • soony changed the title to Supersized cylinder exhaust pipes - LMS loco no 44756

Thanks heaven the BR design team decided to use the pre war German styling on their standards instead of perpetuating the awful "lack of" style Crewe used in the dying days of the LMS.   Couple of decent cures to the running plate, bit of style, maybe some names and the blokes might have taken to them better.   Contemporary reports suggests the drivers were reluctant to open them up due to the very loud exhaust bark making them appear sluggish whereas in fact correctly handled they were both strong and fast .    Maybe they should have fitted inside Stephensons gear instead.

One correction: they aren't exhaust pipes. They are the main steam pipes feeding live steam IN to the steam chests, and onwards to the cylinders. The exhaust passed via branch pipes through the frames and smokebox saddle in the normal way.

They are Caprotti versions. Part of the experiments before building the BR Standards.

But LMS/Ivatt experiments, and although BR did build some standard locos with Caprotti valvegear, they came quite a bit later in the whole process, BR having chosen straightforward Walschaerts gear as standard.

Not that I know much about steam engines, but, pedantically, aren't these BR not LMS locomotives, as they were built by BR in 1948?

 

Mike.

 

It does say that on the Wiki page title. But designed by Ivatt for the LMS.

 

Eventually I want the Comet kit of the low running plate version. At least the valve gear looks simpler...
