33C1 is the designation for the popular UIC33 section (also known as RL-160 or U69) that is used as a guard rail at frogs, as a restraining rail through curves, and as a point guard.
Can be mounted independently from running rail, in a bolted or boltless configuration with VANGUARD(R) plates
Flangeway width adjustable with shims
In restraining rail applications, can be raised to allow for more contact with the back of the wheel, or flush with running rail to avoid contact with snow clearing equipment
May be insulated to facilitate broken rail detection in signal territory
