How to Choose a Proper Railway Turnout?

Speaking of which, you may be surprised that the train driver has no decision at all as to which railway track the train will take. Who will be in charge of turning a train weighing thousands of tons and hundreds of meters, that is, from one railway line to another?  The answer is that they are all controlled by switches laid on the line.  As for which track the turnout opens, it is the responsibility of the station traffic management personnel. railroad switch parts

There are many kinds of equipment on the railway to ensure the safe transfer of trains, the most common of which is a single opening fork, which can make the straight track and trains running on the fork switch to each other, that is, can make the trains turn from the straight track to the fork track or turn from the fork track to the straight track.  In addition to the single turnout, there are double and triple turnouts.  The former connects the straight road with two symmetrical fork roads, while the latter can go straight or branch from the straight road to two different fork roads.

So how can you quickly and accurately select the track suitable for your own railway in so many kinds?  Let's introduce some simple switch selection tips: railroad switch parts

1. For the single turnout connected between the high-speed main line and the incoming and outgoing lines, the No.18 high-speed turnout with a lateral allowable speed of 80KM/H shall be adopted.

2. The connection between the arrival and departure line and the arrival and departure line shall adopt No.18 single turnout with a lateral allowable speed of 80 km/h.

3. The crossing line between the two main lines in the throat area of the station adopts a high-speed turnout with a lateral allowable speed of 80 km/h.  No.12 turnout can be used under difficult conditions for reconstruction and expansion of large stations.

4, tie line and high-speed main line connection switch should be determined according to the speed of the train, using the lateral allowable speed of 160KM/H or lateral allowable speed of 220KM/H high-speed switch. railroad switch parts
