That's a lot of wheels for a four coach train! For a moment I thought you were building one of those 100 ton naval gun transporters: https://www.warwickshirerailways.com/misc/miscfr006.htm.

True Compound , though the CR had their own 100 Ton gun carriers too. A lot of wheels.

Mind you , though they are a bit out of my period I might be tempted one day.

A row of bogies ready

Is the collective noun not “a string of bogies”?

It may well be Regularity. However they have no couplings and so can only be propelled. 

Um, a sneeze of bogies sounds just wrong, 

Two of them will end up with magnetic ajs, but I want the corridor connections to look as if they are connected so I'm going to have to think something up. 

Looks like a smooth ride. I understand these coaches were the pride of the CR. Looking at photos I can see why.

Well I'm sure magnets will end up in the build, been playing with an idea. 

Years ago when I still played with N gauge I had a rake of minitrix coaches which I modified so that the corridor connection acted as the coupling. Just a bit of black rubber with a hole through it and holes on the end of the coaches. A bit of cotton went all the way through the rake and attached to a spring at one end. A bit of a hassle, since you couldn't uncouple it, but it gave the impression of a properly working set of gangways.

I've been conducting thought experiments on how to model a set of close-coupled 6-wheelers. With bogie vehicles, the cam mechanism as used by Hornby and Bachmann is effective but requires the bogie rotation to make it work. I've been toying with the idea of a sprung coupling but there needs to be the right balance between enough force to close the carriages up on the straight and not so much as to cause the set to keel over on the curve...

I've been reading R.M. Casserley and P.A. Millard, A Register of West Coast Joint Stock (HMRS, 1980), in which it is suggested that the celebrated 65'6" 12-wheeled carriages built at Wolverton in 1909 for the 2pm West Coast Corridor Euston - Glasgow, Edinburgh and Aberdeen express were built in response to the Caledonian's Grampian stock, which put the existing WCJS 50 ft arc-roof corridor carriages built at the turn of the century quite in the shade.

In fact, the Caledonian repeatedly appears as the progressive partner in the West Coast Conference, with a sharp eye on what Derby was up to: in February 1876 proposing 47 ft bogie sleeping saloons - from which the LNWR recoiled in horror, insisting on 32 ft six-wheelers for another decade; in 1889, calling for 47'6" bogie tricomposites with lavatories to every compartment - the LNWR baulked at anything longer than 42 ft and insisted on persisting with radial underframes, though relenting so far as to allow the Caledonian to build some with bogies; and of course adopting the Westinghouse brake while still being forced to work the Anglo-Scottish expresses with the Clark and Webb chain brake, until it was able to put its foot down heavily (with the full weight of the Board of Trade behind it) following an accident at Lockerbie in 1883.

Vivat St Rollox!

True Compound, given that it was only a medium sized railway the Caley was something of an innovator, particularly through the Edwardian era. 

These coaches even had hot water for the handwash basins. Total luxury.

Bigger than that upstart Lincolnshire potato railway, though. 

Thats an idea to play with Jim, I have some magnetic rubber sheet somewhere.
