Re: Edington Junction

Dave, I have to say that I share some of Noel's views about the backscene. Here is a selection of views I have culled from Street View and annotated to give some idea of location and direction of shot: Levels horizons.jpg You can see that in some places the line of the Mendip and Polden ridges shows...

Re: Carriage identity query

New picture definitely shows the compartment side of a C77, as per picture GWCA Vol 1 pg 51 plate 128. Agreed, that was the basis of my identification. Are we sure the corridor side of coaches in this era had ventilators? It seems that mostly they did not, but that the C70s were an exception. Due t...

Re: Carriage identity query

John, do you know what the working was; I am puzzled by a WR strengthening coach on an LMR express (presumably) to the south coast? Steve, the photograph from which I snipped the queried carriage is another from Ron Toop's collection, and can be viewed in full at https://www.flickr.com/photos/midso...

I've been trawling for foreshortened views of Sunshine/New-Style carriages in the hope that they might shed some additional light on this issue.

Re: Carriage identity query

Noel, yours is a fascinating suggestion, given the rarity of those two RTO's, but I think that on the corridor side the vehicle in question is symmetrically laid out, whereas the RTO has a longer 'blanked off' section at the end where the air conditioning unit and lavatory compartments are located. ...

Re: MR 1P 0-4-4T detailing

That's a neat design for the brake cylinder, Pete. You appear to have a hole for the inlet pipe from the brake valve at a 45 degree angle from the cylinder centreline, viewed in elevation, yet drawing 91-353S on page 9 of the Wild Swan Profile of the 1833 and 2228 class bogie tanks suggests it shoul...

Re: Arrangement of levers in a signal box (meandering into the Quintinshill disaster)

An example of just such a manoeuvre is illustrated by one of Ron Toop's shots at Radstock at https://www.flickr.com/photos/midsomer-norton-south-station/7264155058/in/album-72157629882634822/ .

A bit of a deviation from the original topic, but since the Jim, the OP, has raised the question about collars I guess he won't mind a bit of thread drift.
