Flat bottom rail

Post by Kelvin White »

How prevalent was the use of flat bottom rail on the Caledonian Railway. Especially on branch & mineral lines. Would it have survived until the grouping.

Thanks

Don't you mean bullhead rail? Flat bottom rail wasn't introduced until the 1950's IIRC and is what is in general use today.

Whilst UK main line railways didn't start experimenting with flat bottom rail until the mid 1930s, it was used on a number of minor lines in pre-grouping days. The Highland used FB spiked directly on sleepers on the Dornoch and Wick and Lybster Light Railways. Perhaps the Caley did on similar minor railways.
Almost certainly some mineral railways would have used similar track, given it was cheaper (with no heavy and costly chairs) and ride quality was not an issue.

Flat bottom rail was used on the Killin, Loch Tay branch when first opened. There are photos of it, on this forum.

Hello Kelvin. I don't have anything to add to what has already been posted, except to say that the Bankfoot branch seems to have been laid with bullhead track from the off, even though it was built under the Light Railway Act. The flat bottom rail on the Killin branch was relaid with bullhead sometime between 1925 and 1930 on photographic evidence.

From the 'Port Line' book, it notes that the Portpatrick Railway (ie west of Castle Douglas) was laid as flat bottom, and the Wigtownshire utilised an even less salubrious and no doubt cheaper still 'single edge rail'.
HMRI reports quoted in the book read as far from impressed in respect of not only rail, but the untreated sleepers and lack of fishplates yet approved the construction for use.

Both later came under Caledonian operation, who did then embark upon improving the lines (before they fell apart).
Which but was last to go ? A guess either somewhere on the Portpatrick line or maybe Garliestown ?

Not directly related to the subject, the West of Scotland 4mm Group are exhibiting a model of Garlieston at Glasgow Model Rail, 24-26th February at SEC.
