I am familiar with the Midland Railway's extensive use of four-bolt chairs in its PW work - but please could someone advise me what other major pre-Group companies used this type of chair as standard?
Many thanks,
Steve

Re: Companies using 4-bolt chairs
The Highland Railway certainly used 4 bolt chairs. Possibly not in the very early days, but thereafter they did.

Re: Companies using 4-bolt chairs
From what I have observed, the North British adopted a four bolt chair as standard. The NB casting was somewhat more bulbous than those I have seen of other pre-group companies, and really does appear to have been secured to the timbers with dome-headed bolts rather than screws. I've yet to see a 4mm chair that looks much like the NB pattern, and fear I never will.

Re: Companies using 4-bolt chairs
The Caledonian certainly used such chairs, at least some of the time; and I have in my possession a North British 4 bolt chair.
Of course, as our esteemed chairman has pointed out, 4 fasteners doesn't mean 4 bolts -- my NB chair has 2 screws, and 2 holes which probably held oak trenails.

The Great North of Scotland were also users of 4 bolt chairs.

Also the Great Northern Railway, although I have no knowledge of any timescale involved.

Re: Companies using 4-bolt chairs
Not quite 'a major pre-Group company', but the Brecon and Merthyr did too.

The LNWR used four hole chairs, with two bolts and two spikes.

Re: Companies using 4-bolt chairs
Thank you gents,
A swift and extensive response indeed - I had no idea how widespread they were! And as Allan F. noted, commonly there were two bolts and two trenails rather than four bolts as such - I should perhaps have asked about four-hole chairs.
A good example of the benefits of coming out of one's own particular trench, for a general recce.
Many thanks again,
Steve

Re: Companies using 4-bolt chairs
Tim, Keith,
Many thanks for the further updates - all responses were very useful; although my earlier supposition that 4-bolt chairs would be one of the more useful diagnostics for unknown scenes (minus vehicles and other obvious company signature features) being on MR territory is now out the window in a big way. Must mug up on signal finials next.....
Keith - particularly useful to be reminded that Digest material is a) highly relevant and b) now also on the website.

Re: Companies using 4-bolt chairs
Also, a bit belatedly, the Great Southern and Western Railway, GSR and CIE, with 4 bolts.
