Movable Point Frog Movable point frog design is designed using standard tee rail sections. These frogs are used in heavy tonnage track, high speed rail or where reduction in noise and vibration is important. These frogs can easily reach over 1,000 MGT's with minimal maintenance. type built in the USA.

The composition of the aforementioned track is primarily comprised of movable point rail, wing rail, check rail, and connection components. It is considered one of weakest part in the track due to its high wheel-rail impacts caused by rail-inherent discontinuities 1, 2, 3.

Wing rail movable type This kind of rail frog structure has fixed crossing nose and movable wing rail. It can be divided into two types one-sided wing rail movable and two-sided wing rail movable. Movable point frog can effectively improve the speed of the train passing through the rail turnout, which is widely used in high-speed railway lines.

A swingnose crossing or moveable point frog is a device used at a railroad switch to eliminate the gap at the common crossing a.k.a. frog which can cause damage and gap of about 10 cm 4 in, supported only by the portion of the wheel tread which is on the wing rail. This pounds the rail so much that the steel can deform andor wear away

voestalpine Railway Systems Nortrak's Moveable Point Frogs add a second throw device to a turnout and are economically viable in high density traffic. They provide impact elimination, noise reduction, very low maintenance and long life because of the continuous running surface.

That is a Movable Point Frog. Movable point frogs are power operated and must be Short portions of the rails leaving the tongue going further into the background are called frog rails. A simple moveable frog is pivoted where the frog rails begin and the pointed tongue tip just wags back and forth between the wing rails.

Progress Rail's Movable Point frog design incorporates standard tee rail sections. These frogs are used in heavy tonnage track, high-speed rail or where the reduction in noise and vibration is important. These frogs can easily reach over 1,000 MGT's with minimal maintenance. The simplicity of our Movable Point Frog's design makes it the

Movable point frog swingnose crossing Unlike the fixed railroad frogs, movable point frogs have special movable components such as movable wing rails or movable crossing nose. By changing the position of the movable part in the frog, the working side of the wing rail or the crossing nose can be overlapped to provide a continuous trajectory

of the point. For larger geometries, point and splice rails are bolted together in a rigid way. To comply with highest safety requirements, the point and splice rails are addi-tionally connected via a form-fitting safety plate. Wing rails The wing rails are produced out of symmetrical rail pro-files. Wing rails and the crossing vee are machined to
