Capacity of a catch siding is ________. A. Equivalent to length of full train B. Length C. Station D. None of these

The correct answer is: A. Equivalent to length of full train.

A catch siding is a short siding, usually located near a station, that is used to hold trains that are waiting to enter the station. The capacity of a catch siding is the length of the longest train that can be accommodated on the siding.

Option B is incorrect because the length of a catch siding is not necessarily the same as the length of a train. The length of a catch siding will depend on the amount of space available and the needs of the railway.

Option C is incorrect because a catch siding is not a station. A station is a place where trains stop to load and unload passengers and freight. A catch siding is a place where trains wait to enter a station.

Option D is incorrect because catch sidings do have a capacity. The capacity of a catch siding is the length of the longest train that can be accommodated on the siding.
