Railroad Track Switches Railway Turnout Railroad Switch  Introduction

Turnout is the basic setting that divides a track into two or more tracks, so that the rolling stock can be transferred from one line to another. Turnout number is represented by frog number. The intersection angle of working sides at both sides of crossing center is called frog angle, and the cotangent value of frog angle is called frog number.  

The commonly used turnout is divided into single turnout, symmetrical turnout, compound turnout and crossing line. Turnout is a special track equipment, which not only affects the safety of train operation, but also has a shorter service life than other equipment, and has a large amount of maintenance work on site.

The most commonly used single turnout in China, the main line of which is straight line, the side line is left or right turnout from the main line, also known as left turnout and right turnout, the number of which accounts for more than 90% of the total number of all kinds of turnouts.

Characteristics of Railroad Track Switches Railway Turnout Railroad Switch 

Single turnout is one of the common railway fittings. It is a kind of movable frog single turnout. It refers to that the individual parts of the frog can move, so as to prove the continuity of the track when the train passes through poverty, eliminate the harmful space on the fixed frog of single turnout, and cancel the guard rail. At the same time, the geometric smoothness of single turnout can be greatly reduced on the vertical section, so as to significantly reduce the single turnout The wheel rail interaction at the frog part of the turnout improves the operation and stability, and prolongs the service life of the frog.

The long-term operation practice shows that the service life of the movable frog is 6-9 times of that of the whole cast frog of the same type of high manganese steel, the maintenance workload is reduced by 40%, the impact force of rolling stock passing through is greatly reduced, and the allowable speed and implementation comfort of the single turnout are improved.

There are twenty-one series of turnout series 608, 612, 615, 715, 915, 618, 718, 918, 622, 722, 922, 624, 724, 924, 630, 730, 930, 938, 643, 50 and 60.

There are seven types of turnout: single turnout, symmetrical turnout, crossover, cross crossover, symmetrical combination, diamond crossing and four track set.

There are four kinds of gauge: 600, 762, 900 and 142.

There are 11 rail types: 8, 12, 15, 18, 22, 24, 30, 38, 43, 50 and 60.

Frog No. 2, 3, 4, 5, 6, 7, 8, 9 and 12.

There are 11 kinds of curve radius: 4, 6, 9, 12, 15, 20, 25, 30, 40, 50, 70.

There are ten kinds of line spacing: 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2200 and 2500.
