In my commuting days I often saw parked at Bromley South station an elaborate locomotive with projecting arms designed to maintain the track. I think its main function was to manipulate the ballast so that it kept the sleepers, etc in correct alignment, a job presumably otherwise done manually.
I saw one of these in action on a Saturday night on the Hastings line in Tunbridge Wells.
It would stop and the arms were jammed down between the sleepers deep into the ballast. They then vibrated vigorously to fluff up the ballast – it made a lot of noise and the ground shook. The arms were then retracted and it moved forward to the next set of sleepers.
You could see through a window into the control room with two or three operators and loads of computer monitors and coloured lights.
It was quite a sight – and sound.
