Turnout encyclopedia

There are three basic forms of turnouts: line connection, crossing, combination of connection and crossing.  Common lines are connected with various types of single turnout and compound turnout.  The crossing has vertical crossing and rhombus crossing.  The combination of connection and crossing includes crossing points and crossing lines, etc.  Common types of turnouts include single turnouts, triple turnouts, cross turnouts, traffic separation basins and crossing basin etc. railway turnout suppliers

The most common is the common single switch.  It consists of switch, connecting part, frog and guard rail.  Switch includes basic rail, switch rail and switch machine.  When rolling stock is to be transferred from the A-share track to the B-share track, the switch machine is operated to move the switch rail. railway turnout suppliers

The switch rail 1 is closely attached to the base rail 1, and the switch rail 2 is separated from the base rail 2. Thus, the B-share track is opened and the A-share track is closed. The rolling stock enters the connecting part and transits along the guide curve track to the frog and the guard rail unit.  This unit includes fixed frog center, wing rail and guard rail. Its function is to protect the wheels from crossing the two tracks. railway turnout suppliers
