    A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. [ 1 ]

    A copy of the 2002 edition of the National Routeing Guide. The railway network of Great Britain is operated with the aid of a number of documents, which have been sometimes termed "technical manuals", [1] because they are more detailed than the pocket-timetables which the public encounters every day.

  7. List of steepest gradients on adhesion railways - Wikipedia

    These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man.
