The frequency of buses on the C10 route (Canada Water to Victoria via Elephant & Castle) is to be increased.
Transport for London has re-awarded the contract to run the route to Abellio London.
Under the new contract which begins in March 2016, a new fleet of single deck buses will be introduced.
The number of vehicles required to run the route at peak times will be increased from 15 to 19.
At present the C10 runs every 10 minutes at peak times and every 12 minutes during the day.
