Why me? Why cannot someone else ask the tricky Questions?There's nothing like a straightforward question Graham...
Your right Bob - that is nothing like a simples question . I did have to lie down and think through the questions before I wrote the post .... your right Bob - That's nothing like a straightforward question I'll have to go and have a lie down before answering that one...!
Tried the obvious... and we are talking about a class which became extinct in 1977 as far as the railway workshops were concerned.Have you tried the NRM? Failing that how about asking on the Western Locomotive Association forum?
Mk.1 carriages ran on different types of bogies over the years... BR standard, Commonwealth and B4.... with some carriages changing bogie type during a works repair. Just how interchangeable were the bogies for any given carriage? What underframe modifications were necessary to make a change of bogie type?
For example:- could a carriage built with CW be changed to B4 and then back to CW?
One bogie change which interests me is BR (equalised brake gear) to B4... easy or needs the modelling toolbox?
Oh, go on then. BR (unequalised brake gear) to CW or B4.
Thanks, Graham
Way back when, in this post, Bob kind of challenged the WT world by suggesting that the odds were heavily against finding an exception to the "norm" in regard to Mk.1 brake gear arrangements, viz:-I wouldn't hold your breath just yet Graham - the odds are still against you
Whatever happened in the post BR / private / preservation era doesn't count!
Apart from Bob, Heather and I, who might be interested in such a posting?
And that's despite me thinking that because of its ubiquity the Mk1 is probably the most boring carriage we've ever had in the UK...

No No No! To paraphrase George Orwell - Underframe & Solebars Good! Integral Design Bad!
You are a real heathen... the Mk.1 concept is a magic piece of engineering for its day / purpose / construction (and other -ologies). The Mk.1 carriage is as much a work of art as the Routemaster, the Landie, the Comet and other pieces of English engineeering....

Seems that I had overlooked Rule 4 which Bob says goes something like this:-Way back when, in this post, Bob kind of challenged the WT world by suggesting that the odds were heavily against finding an exception to the "norm" in regard to Mk.1 brake gear ...
Well, looks like Bob might have found an exception. This Wiki page details some of the preserved Mk.1 TPO sorting carriages and at least W80349 seems to be an exception to the rule.
Way back when... sometime in the depth of winter... Bob offered a challenge, in post no.#132 , something along the lines of "if you can find anything different to etc., etc.." . I spotted something last week which might just be an answer to Bob's prompt.
Parked out back at the NRM last week was a Mk.1 BG, painted in mock LNWR livery and named "Valiant"... no number visible. What was surprising about this carriage was that the underframe was carried on Commonwealth bogies whilst the vacuum cylinder was supported in symmetric V-hangers with the brake pull rod going under rather than over, the bogie headstock / axles. This arrangement of brake gear is not meant to happen... and I cannot work out how the brake pull rod connects to the equalising fulcrums of the Commonwealth bogie.
No photo's??. You should know better.
The number was 81025, or 84025, or even 99782. Take your pick.

I've no idea (without doing a bit of digging) how they coupled that up.
