What are the standard turnouts prescribed on Indian Railways?

On Indian Railways, normally 1 in 8.5 turnouts are used for goods trains while 1 in 12 and 1 in 16 turnouts are used for passenger trains. Recently 1 in 20 and 1 in 24 turnouts have also been designed by the RDSO, to be used to permit higher speeds for fast trains on the turnout side.

What is the difference between turnout and crossover?

Basic types of turnouts include a “Single turnout” that diverges one rail track into two directions, a “Diamond crossing” that intersects two tracks,and a “Crossover” that connects two side-by-side tracks.

What can be done to improve the speed of trains over turnouts?

10. What can be done to improve the speed of trains over turnouts? Explanation: At turnouts, the vehicle sometimes cannot achieve good speed because of sudden change in direction of vehicle upon entry. Long curved switches can be provided to avoid this problem.

What is railway toe?

 Tongue rail (Switch rail)  Rails which lie between the 2 stock rails  End portion of the tongue rail is called toe and is connected by stretcher bar .  It is the moving part of the switch which diverts the train from one track to the other.

What is railway TRR?

Through Rail Renewal (T.R.R.) is carried out after the track gets consolidated by three rounds of through packing and also on account of passage of trains. This method can be carried out when the section of the new rail is the same as the existing rail or where 90-R rails are renewed by 52 kg.

What is railway Triangle?

In railroad structures, and rail terminology, a wye (like the ‘Y’ glyph) or triangular junction is a triangular joining arrangement of three rail lines with a railroad switch (set of points) at each corner connecting to each incoming line. A turning wye is a specific case.

What is railway crossover?

A Crossover is a pair of complementing Turnouts linked by common Closure Rails. They allow a transition between two parallel tracks.

What is railway heel block?

Heel block assemblies are units placed at the heel of the switch that provide a splice with the contiguous closure rail and a location for the switch point rail to pivot at a fixed spread distance from the stock rail. Switch point rail stops act as spacers between the switch point rail and the stock rail.

What is a double slip switch?

A Double Slip Switch (DSS) connects a series of parallel tracks to allow a train to cross over on to any track no matter which direction it is going. A train approaching the arrangement may leave by either of the two tracks on the opposite side of the crossing.

What is the salary of TTE?

How many turnouts are used in Indian Railways?

On Indian Railways, normally 1 in 8.5 turnouts are used for goods trains while 1 in 12 and 1 in 16 turnouts are used for passenger trains. Recently 1 in 20 and 1 in 24 turnouts have also been designed by the RDSO, to be used to permit higher speeds for fast trains on the turnout side.

What are the speed restrictions on Indian Railways?

Most turnouts have speed restrictions of 25km/h (1 in 12 or easier). Sharp turnouts (1 in 8, NG turnouts of 1 in 8.5, etc.) are limited to 15km/h or even 10km/h or 5km/h in some cases. (A few NG lines have even sharper turnouts; e.g., the DHR has a 1 in 5 turnout and 1:4 crossings. Speeds are restricted appropriately in such cases.)

What’s the average speed of a turnout in India?

* As per the Indian Railway way and works (IRWW) manual, a speed of 15 km/h was originally permitted on 1 in 8.5 turnouts. However, due to a subsequent number of derailments of passenger trains on turn-in curves, the speeds on these turnouts have row been reduced to 10 km/h only.

What should be the speed of a train over a turnout?

� A speed of 30 km/h is also permitted on 1 in 12 turnouts on those interlocked sections where all turnouts over which a running train may pass are 1 in 12 throughout the section and the locomotives are fitted with speedometers. In all other cases, speed is restricted to 15 km/h only.
