Rail Chairs

[jim mac]

Our colleagues in the Highland Railway Society have been discussing Rail Chairs on their forum and Howard Geddes has drawn their attention to the following links http://etheses.dur.ac.uk/1484/1/1484_v1.pdf and http://etheses.dur.ac.uk/1484/2/1484_v2.pdf which explore the business of Anderson Foundry owned by J C Bunten of Dunalastair. There are also a number of references to business with the Caledonian Railway

Interesting study. Thanks for the post.

I would be interested to know the sleeping arrangements around the crossing unit, are their any further details on this subject?
I have a few more turnouts to build for the layout so could start building them to the correct sleeping arrangement.

Regards

David

As part of the exchange on the HRS Forum, Jim Summers quoted from his piece in TTL115 on Matheson's report on American practice. This generated a reply which included the attached NBR diagram, which originally had been supplied by Jim Watt. A general view by most respondents to the topic is that all the Scottish Coys had similar arrangements.

Attached is an image of the sleepering and chairing around the crossing vee of a Caley interlaced point. Apologies for the standard of reproduction - it's a scan from part of a tracing that I took from plans in the National Archives. The haphazard nature of the sleepers isn't down to poor tracing, that's just how they appeared on the Caley drawing.
