rail

The rail profile is the cross sectional shape of a railway rail, perpendicular to its length.
Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section (profile) approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below). The head is profiled to resist wear and to give a good ride, and the foot profiled to suit the fixing system.
Unlike some other uses of iron and steel, railway rails are subject to very high stresses and are made of very high quality steel. It took many decades to improve the quality of the materials, including the change from iron to steel. Minor flaws in the steel that may pose no problems in other applications can lead to broken rails and dangerous derailments when used on railway tracks.
By and large, the heavier the rails and the rest of the trackwork, the heavier and faster the trains these tracks can carry.
Rails represent a substantial fraction of the cost of a railway line. Only a small number of rail sizes are made by steelworks at one time, so a railway must choose the nearest suitable size. Worn, heavy rail from a mainline is often reclaimed and downgraded for re-use on a branchline, siding or yard.

    Should I expect my towel rail (non electric) to be fitted like this

    I’ve paid good money for a bathroom installation. This follows on from having an en-suite installed last year.

    Leaking dual fuel towel rail

    Hi, hoping someone can help. We have a dual fuel towel rail, i.e. connected to the central heating, but with an electric element in one of the "legs".

    Towel rail advice - dual fuel, rather than just electric?

    Hopefully this is a quick one... I'm currently building a house (well, my builder is, I'm doing a few of the jobs myself). Originally, we were going to have electric towel rails in the bathrooms, because we were going to have solar panels. We're over budget, so the panels will have to wait...

    How to drain down to remove towel rail AND valves?

    Towel rail needs to be removed so that new flooring can fit over pipes. Therefore the whole thing needs to come off valves and all so that the pipe ends coming up from the floor are exposed. The bottom compression nut and olive can stay on each pipe as there will be big enough holes in the...
