manufacture and supply of Friction Buffer Stops with different
working mechanism methods (friction, hydraulic), and different
amount of energy absorption for restrain Passenger Trains; Freight
Trains; locomitives; and Railbound Construction and Maintenance
Machines ("Railway Vehicles") in emergency cases without
serious injury to the driver and passengers and minimum impact to
the vehicle construction.
1.2
In additionally these technical specifications describe the
requirements for the manufacture and supply of Fixed Buffer Stops
to be installed on track ends.
1.3
In additionally these technical specifications describe the
requirements for manufacture and supply of Braking Wheel Stops
Sets (*), to be installed on rail heads to use on depot tracks and
marshalling yard tracks to stop track motor vehicles, locomotives
or light train. ISR using wheels of several diameters the wheel
profile types are in accordance with UIC510-2; EN13715 --- wheel
type S1002 : h=28, e=32.5, reverse slope 15%; and with DSB82-1
wheel profile type (IC3 trains) (see Technical Appendix A).
(*) Braking Wheel Stops Set - means two braking wheel stops, one
for each rail of the track.
