London Assembly Conservatives Group transport spokesman Richard Tracey has called for the Underground to become driverless.
The proposals are contained in a memorandum sent to London mayor Boris Johnson and the transport secretary Phillip Hammond.
Tracey urged Johnson to examine and press ahead with the idea.
“Driverless train technology is in operation all over the world. It is safe, efficient and reliable,” he said. “Once the Tube upgrade is completed, the Underground will essentially be an automatic system, with drivers reduced to door openers.
“After extensive research of what is possible in London and looking at other metros around the world, we have concluded that the Underground could quite easily become a completely driverless system, saving hundreds of millions of pounds a year in staff costs,” said Tracey.
“In a time, when as a country we’ve all got to cut our coat according to our cloth this is a proposal that should be grasped with both hands. Not only because savings on staff could be directed into other transport investment, but because in and of itself it would be a far superior way to run the Underground.
