Frogs

A frog is a track structure used to form the intersection of two running rails. It permits wheels on either rail to cross the other rail.

Explosive-Hardened Frogs

Explosion hardening is normally done to intermediate-wall-design railbound manganese-steel frogs and to 1″ side wall solid-manganese frogs.

Features and Benefits

Running surfaces hold their shape during initial service, reducing the need to grind surplus metal from flangeways and/or to weld additional metal to running surfaces. Any concealed flaws are exposed. An unsound casting will not survive explosion hardening.
