Workers attempting to clean up the cement-filled Victoria Line signal room rushed to a local supermarket to buy bags of sugar to prevent it from setting.
Victoria Line services were closed between Warren Street in the centre of the capital and Brixton in the south after a cement leak from a nearby construction area damaged the control room.
The problem has since been resolved and the line was once again running a good service.
The operations director for the Bakerloo, Central and Victoria lines paid tribute to the engineers who "worked tirelessly through the night" to repair the damage.
