Some factors affecting Working of Yard
- Lack of proper advance planning and co-ordination between control and, Yard, loco shed, C&W.
- Yard has to plan in consultation with Control and adjacent Yards.
- While breaking up of terminating trains local wagons are not properly collected in specified lines and remain scattered in Sorting and Marshalling lines or other parts of yards.
- Late or irregular removal of loads from local areas affecting timely placement of wagons.
- Empty stocks, sick wagons and wagons for load adjustment lying scattered in the yard hampering Yard operations.
- Higher wagons balance in Yard affects mobility.
- Highest wagon balance beyond which mobility will be seriously affected should be worked out for each yard and yard balance should be constantly monitored to see that it is not exceeded.
- Efficiency of Yard shunting engine. Efficiency and sufficiency of Yard shunting engines should be periodically watched.
- Repairs should be attended promptly.
- Yard layout – Features of Yard like wrongly placed cross over, short shunting neck, or isolation of two busy groups of lines can restrict working of yard.
- Minor addition/modification proposal should be forwarded.
- Delay in release of wagons by public and departmental consignees can cause heavy accumulation of wagons.
- Advance information should be given to rake handling parties and departmental supervisors.
- Late start of trains from yard.

- As far as possible movements in several marshalling movements should be continuous and progressive in the direction of destination of wagons.
- Reception line, sorting line, shunting neck, marshalling lines, departure lines should be arranged with this objective in view.
- Maximum flexibility in movements - Simultaneous reception of trains from different directions.
- Simultaneous despatch of trains to different directions.
- When 2 or more Shunting engines work they should not interfere with each other by provision of separate shunting necks.
- Reception of train not to interfere with the Despatch of another train and vice-versa.
- Reception of one train not to interfere with shunting in another part of the yard.
- In large Yards there should be separate liens for Reception, Marshalling and Despatch. Bypass running line may also be provided.
- Adequate lighting and communication in different parts of yard.
