What is BS EN 16839 - Head stock layout for railway application about?
BS EN 16839 discusses railway application. BS EN 16839 is a European standard that provides a headstock layout for rolling stock in railways.
BS EN 16839 outlines the location, fixing, and free spaces on the headstock of:
- Buffers
- screw coupling systems
- end cocks
- pneumatic half couplings
- connections for electric cables
BS EN 16839 also specifies the calculation of the width of the buffer heads
Note 1: Unless otherwise displayed, all dimensions given in this European Standard are nominal values.
Note 2: Some parts of BS EN 16839 are copied from EN 16116–1, EN 16116–2, EN 15551, and EN 15566. These parts are meant to be deleted from these ENs during their next revision.
Who is BS EN 16839 - Head stock layout for railway application for?
BS EN 16839 on the head stock layout for railway application is useful for:
- Manufacturers of buffers for railways
- Test centers
- Regulatory authorities
Why should you use BS EN 16839 - Head stock layout for railway application?
To allow operation and coupling of trainsets or vehicles, BS EN 16839:2017 outlines the defined free space for the shunter called the “Berne rectangle” and the necessary free space for the installation of the rescue coupler.
BS EN 16839 guideline assists by guiding Berne rectangle, climb protection, free spaces for coupling of passenger vehicles, distance between buffers, the height of buffers above the top of the rail, vehicles without crashworthy buffer systems, vehicles with crashworthy buffer systems, interaction coupling/buffer, mounting of buffers, the position of draw gear on the headstock, the position of the device to hang the screw coupler when not in use, draw gear fixing, brake pipe connections, pneumatic half couplings, electrical connections and more for headstock layout for railway application.
This ensures free space that is needed to ensure safe working conditions for the shunting staff during coupling and uncoupling of screw couplings.
