The Canada Water Underground station is to be renamed Buxton Water for the day of the 2015 London Marathon, Transport for London (TfL) has confirmed.

The move is expected to generate £110,000 for TfL from the brand, which is also sponsoring the marathon. It is part of a wider bid on the part of TfL to raise £3.4 billion in non-fare revenue over the next ten years, and is supported by local Conservative officials.

The temporary rebrand will involve changing roundels and station artwork, although the exterior signs and maps will remain the same. Information will be displayed to reassure passengers that the name change is for one day only.

Rail union RMT has criticised the decision, promising to oppose any permanent rebranding. However, TfL’s Graeme Craig, director of commercial development, defended the plans, saying: “This is a significant deal and the revenue will be reinvested back into our network for the benefit of our customers.”
