A scissors crossover is meant for transferring a vehicle from one track to another track and vice versa. It is provided where lack of space does not permit the provision of two separate crossovers. It consists of four pairs of switches, six acute crossings, two obtuse crossings, check rails , etc. On account of vertical impact due to speed and rail vibrations, etc, the dynamic load is much more than the static load.
The dynamic wheel load is obtained by increasing the static load by an incremental amount given by the speed factor. Till , Indian Railways used the Indian Formula for calculating the speed factor. After , German Formula was adopted by Indian Railways for the calculation of speed factor. The driver interprets the signal's indication and acts accordingly. Typically, a signal might inform the driver of the speed at which the train may safely proceed or it may instruct the driver to stop.
Classification of signals:- Railway signals can be classified based on different characteristics as presented below in table.
From the above table, we can see that advanced starter signals are a locational signal, not a functional signal. Hence the answer to the question is option 3. Additional Information. T he further classification of audible and visible signals. Further classification of signals on the basis of the different types of stations are:. Start Learning. Broken stone Gravel Moorum All of the above. Explanation: The following materials for Ballast can be used on the railway track.
Broken Stone 2. Gravel 3. Sand 5. Kankars 6. Moorum 7. Brick Ballast Among above materials, broken stone from Igneous rocks like quartzite and granite forms the excellent ballast materials. Some of the main functions of ballast are followings: a To provide firm and level bedded foundation for the sleepers and rails to rest on b To protect the surface of subgrade and to form an elastic bed c To transmit and distribute the loads from the sleepers to the subgrade d To allow for maintaining correct track level without disturbing the rail road bed e To hold the sleepers in position during the passage of trains f To provide lateral stability to the track as a whole.

Concept: The points and crossing are the vital components of track asset ; necessary for diversion of traffic from one track to another track, such diversion may be necessitated for giving precedence to faster trains in the same direction, giving passage to a train moving in the opposite direction or for connecting places not on the direct line of the track.
Constituents of the points and crossing are explained below: 1. Turnout - The term denotes points and crossing with the lead rails. Stock rail - It is the running rail, against which a tongue rail functions.
Marshalling yards Locomotive yards Station yards Goods yards. Concept: The yard is defined as a system of tracks laid within definite limits for various purpose such as storing of vehicles, making up trains, dispatch of vehicles, etc. For convenience, the classification of railway yards is done following four categories are as follows: i Passenger Yards ii Goods Yards iii Marshalling Yards iv Locomotive Yards v Sick Yards Marshalling yards: Marshalling Yard is a place where goods trains are received, sorted, reformed and dispatched.
Functions of marshalling yards: a Reception b Sorting c Departure Types of marshalling yards: a Flat Yard- used where space is limited b Gravitational yard - Used where the ground is sloppy.
