Railway Turnout

Railway Turnout Components:

Railway Turnouts and crossovers are a set of railway parts at the crossing point of several rail tracks, which helps trains change tracks to other directions. Railway Turnout include following items:switches, frogs, guard rails, stock rails, and closure rails; rail fasteners made for turnouts and other components including switch rods and gauge plates, etc.At the railway track turnout section, single and double slip switches, cross ties are also specially designed and fabricated for rail turnout system. AGICO can supply various types of railway frogs and switches for different requirements.

Railway turnout is widely applicated in railway stations and marshalling stations, it helps increase carrying capacity of railway lines to avoid railway lines being used by single train for single direction. So with railway turnout being used, it is possible that 2 trains can run on single railway line from opposite directions.

Railway Switches

Railway switch include 3 main parts: switch rod, switch motor, point(switch rail), its working method: powered by switch motor, switch rod will reposition the switch rail before train passing through, to reach the purpose of changing railway lines.

Railway Turnout Types

According to turnout detailed function, turnout is generally categoried into Single Crossover, Double Crossover, Track Crossing, Slip Switch and Lapped Turnouts.

Single Crossover Turnout

Single Crossover is composed of two turnouts positioned in two tracks that allow the vehicle to go from one track to another. A pair of single crossovers is also called universal crossover-one right hand and one left hand.

Double Crossover Turnout

Double Crossover, also named scissors crossover, consisted of 2 crossovers of opposite hand orientation positioned upon each other, extra part a track crossing diamond is needed. Double crossover turnout can make trains switch from both tracks to the other in either direction.

Track Crossing Turnout

Track crossing turnout allows 2 or more railway track cross each other, while extra part of crossing diamonds are needed.

Slip Switch Turnout

The more complex slip switch allows trains to both cross and to change tracks: slip switch is more compact than ordinary turnouts. As a result, they are often found in high track density areas such as passenger terminals, where space is at a premium. This makes trains can cross rail track or change into another rail track.

Railway Frog Parts and Types

Railway frog, or railway crossing, is a section of steel rail crossing point of 2 rail tracks, a frog is the built up pieces of trackwork that allow 1 rail to cross another with an opening for the wheel flange, found on turnouts and diamonds were 1 rail intersects another, rail frog can be cast as 1 piece or fabricated with 2 or more number of rail tracks, railway frogs has developed into many types.

Frog is composed of two point rails, two wing rails, two guard rail (also named check rail), tie plate, blocks, other accessories and etc. According to different production technologies, Frog include the following types: rail bound welded frog (RBW), welded boltless manganese frog (WBM), welded spring manganese frog (WSM), rigid bolted frog, rail bound manganese steel frog (RBM), solid manganese flat top steel frog, solid self guarded manganese steel frog (SSGM), (partial) flange bearing frog, jump frog, moveable point frog.
