In the good old days of the GWR and then Western Region, quieter signalboxes were switched out at night and/or at weekends.
In operating terms, the signal box had ceased to exist until it was switched back in. Its work was done by the signal boxes either side.
Did such a thing happen in the old days of individual signalboxes on London Underground?
