I know little or nothing about the running of the railway, but I do have curiosity about it.
I am very close to the Brighton Line and at fairly regular intervals see Network Rail flying a helicopter along the line, a few hundred feet up, presumably inspecting the line in some way.
I am curious to know, in general terms, what they are likely to be looking for and what special kit they might carry to assist in the task.
