First of all, every commuter rail system has full time maintenance crews, and they always have plenty of work: changing lightbulbs in the tube, fixing a signal that got bumped, replacing an on-track communication cable that was vibrated out of place and smashed, etc.

In the past month Londoners have faced delays on the Tube because of over-running repairs, cracks on the lines, signal failures and faulty trains.

At first, devices that needed to amplify a signal such as radios and the first, lumbering computers used the vacuum-tube amplifier.
