SOLID MANGANESE SELF-GUARDED FROGSA Solid Manganese Steel Self–Guarded Frog is constructed with guides or ˚anges above its running surface. These ˚anges contact the tread rims of the wheels and safely guide the wheel ˚anges past the point of the frog. Thus, the self-guarded frog does not require the use of guard rails. This type of frog is used for yard tracks and main line tracks where the speed does not exceed 30 mph.
