The correct answer is: B. C & W
C&W stands for Construction and Maintenance of Way. The C&W department is responsible for the maintenance of the railway track, including the ballast, sleepers, and rails. They are also responsible for the construction of new railway lines.
When a material train is working in a block section, the C&W department is responsible for protecting the train from oncoming traffic. They do this by placing warning signs and signals, and by working with the train crew to ensure that the train is safe to operate.
The other options are incorrect because they do not refer to the department that is responsible for the maintenance of the railway track.
- Option A: Operation refers to the department that is responsible for the operation of the railway, including the scheduling of trains and the dispatching of train crews.
- Option C: Engineering refers to the department that is responsible for the design and construction of railway infrastructure, including railway lines, bridges, and tunnels.
- Option D: None of these is the correct answer because it does not refer to the department that is responsible for the maintenance of the railway track.
