Abstract
A turnout for a railway track having a raised track surface to provide a path along which the wheels of a train can travel from one railway track to another. The raised track surface is of a sufficient height such that the wheels of the train are arranged to clear each railway track being crossed. The turnout facilitates Single Line Working on a second railway track to clear a first railway track for maintenance or other purposes. Pot sleepers for supporting rails of a railway track (10) and a method of installing them is also described.

An apparatus for facilitating Single Line Working on a second railway track to clear a first railway track for maintenance or other purposes, the apparatus comprising a first non-intrusive crossover and a second non-intrusive crossover being spaced apart from the first non-intrusive crossover in the direction of the longitudinal axis of the pair of railway tracks, and which provide a path along which wheels of a train can travel from the first to the second railway track and from the second to the first railway track.

A method which enables Single Line Working on a second railway track to clear a first railway track for maintenance by other purposes, the method comprising the steps of:
- providing a first non-intrusive crossover;
- providing a second non-intrusive crossover at a location which is spaced apart from the first non-intrusive crossover in the direction of the longitudinal axis of the pair of railway tracks;
- passing the train along the first non-intrusive crossover;
- passing the train along the portion of the second railway track between the first and second non-intrusive crossover;
- passing the train along the second non-intrusive crossover, such that the train is returned to a location on the first railway track which is spaced apart in the longitudinal direction from the first non-intrusive crossover.
A pot sleeper for supporting a rail of a railway track, the pot sleeper comprising:
- a body having an, in use, substantially planar upper surface onto which rails may be connected;
- front and rear faces which extend downwardly at an angle to the upper surface, the faces having lower contact edges for contact with the ground;
- and
- a pair of side ends which extend downwardly at an angle to the upper surface for a greater distance than the front and rear faces.
