What is fouling point?
What is fouling point?
The point on a pair of converging tracks where the two trains would collide side on if allowed to approach together.
What is fouling point in railway?
Fouling Mark is a point to the rear of a converging junction, such train must be to the rear of that point in order to ensure that any train moving on the other converging line can proceed without being obstructed. Purpose is to avoid collision between two trains on adjacent track.
What are points and crossings?
Points and crossings are provided to help transfer railway vehicles from one track to another. The tracks may be parallel to, diverging from, or converging with each other. Points and Crossings. Introduction. Points and crossings are provided to help transfer railway vehicles from one track to another.
What is clearance point?
noun In railroading, the point at a siding where the siding-track is sufficiently far from the line-track to allow a train upon the one to clear or pass a car standing on the other.
Where is fouling mark provided?
A fouling mark (Fig. 27.12) is provided between two converging tracks at the point beyond which the centre-to-centre distance of the track is less than the stipulated minimum distance. This minimum distance is 4.265 m for BG and 3.66 m for MG lines.
What is fouling mark and its application?
This mark is called Fouling Mark and is the mark at which infringement to Standard Dimensions occur where two lines meet or cross each other. It is the responsibility of the driver to ensure that the engine is clear of the Fouling Mark and the guard to ensure that the Fouling Mark is cleared by the last vehicle.
How do train points work?
When the wheels reach the switch, the wheels are guided along the route determined by which of the two points is connected to the track facing the switch. In the illustration, if the left point is connected, the left wheel will be guided along the rail of that point, and the train will diverge to the right.
What is tongue rail?
Tongue rail – It is a tapered moveable rail connected at its thick end to lead rail. The tapered end is called as Toe and thick end is called a Heel. Stock rail – It is a running rail against which tongue rail functions. Point – A pair of tongue rails with their stock rails is termed as a point.
What is CSL railway?
clear standing length means distance between foot of the signal to the fouling mark in the rear of the same line in case of main line and directional loop lines at station yards.
What is a frog on a railroad track?
The frog, also known as the common crossing (or V-rail in Australian terminology), is the crossing point of two rails. This can be assembled out of several appropriately cut and bent pieces of rail or can be a single casting of manganese steel.
How do you find the fouling point of a track?
2. The fouling point occurs where the distance between the running edges of the two rails is 1970mm, measured at right angles from the diverging line. 3. In the case where tracks become parallel with a running edge separation of less than 1970mm, the fouling point occurs where the tracks first become parallel.
What is a fouling point on a motorway?
This is a position a short distance away from the point of running line divergence (crossing nose). Should any part of a vehicle on one track be between the crossing nose and the fouling point, it will make physical contact with any vehicles passing on the other route.
What are Aldon track clearance markers used for?
Aldon clearance fouling markers Aldon track clearance markers prevent collisions on converging tracks. Prevent fouling of switches and converging rails. Aldon Company, Inc
What does a yellow urethane marker look like?
Low-profile bright yellow urethane marker to indicate parking limits on tracks encased in concrete or asphalt. Marker is 36″ long by 6″ wide and 1″ thick. All four sides of the marker are beveled to avoid being caught by snow plows. Keep the marker visible in winter by sweeping it clear of snow when you clean the switch points.
