London Buses route T31 is a Transport for London contracted bus route in London, United Kingdom. The service is currently contracted to Arriva London. The service is a Tramlink feeder route, connecting at Addington Village Interchange tram stop and bus stop. TfL liked the idea of having feeder routes for the tram, as at the time it was in the direction the Mayor of London was thinking in, more London buses. Along with more buses there was an aim for better frequency (especially in South East London where the average frequency is just around 12 minutes). So this new trend of feeder buses started with this route T31 followed by routes T32 and T33.
