in the past I have seen a mixture of chairs fitted to tracks, L.M.S & B.R together.

Do you have any pictures of the 2 types? I’d like to know what the difference is.in the past I have seen a mixture of chairs fitted to tracks, L.M.S & B.R together.

If a rail has been down for a long time in the open air, is it possible that it can be affected by the weather? I was lifting some rails from the old carriage shed at Drayton Park when doing volunteer work for the Ffestiniog Railway back in the late 1970s, and I was working down in an inspection pit. I happened to look along the top of the rails coming into the shed (my head was level with the rail-head) and noticed that there was a slight but definite drop in the rail-head at the point where the shed ended and where they were then out in the open, a couple of millimetres. I can't think of any reason other than this being the result of their having been exposed to the rain for many decades. Might there be some other reason than weathering?Lasted well then! But then as it's not exactly taking heavy traffic at speeds it probably hasn't worn out significantly, most of those sidings would be either lightly used or just holding stock a lot of the time.
The track in the shed is probably on a firm concrete foundation but that outside may be ballasted. The ballasted part may settle, particularly in a low speed depot area where there's no need to tamp it to attain a perfect level.If a rail has been down for a long time in the open air, is it possible that it can be affected by the weather?

That's a good point. From what I recall, the track outside the shed was on ballast, but inside it was on longitudinal sleepers which sat in concrete. Settling into the ballast, and thus bending the rail, is indeed plausible. The drop in height of the rail-head seemed quite abrupt, but that might have been because I was viewing the rail at rail-head height along it from some distance, and thus my view was foreshortened.The track in the shed is probably on a firm concrete foundation but that outside may be ballasted.
