By far the longest serving advertising livery on a modern tram in the UK is this Love Croydon design on London Tramlink 2554, which has now reached eight years having first been applied during June 2012. With the Borough of Croydon having part funded the new Stadler Variobahn trams which were first introduced in 2012 this advert was applied to recognise this fact and has remained in situ ever since - and is currently the sole non-fleet liveried tram in the Tramlink fleet. We see the tram here at Therapia Lane on 7th September 2012 working a line 4 service to Elmers End, which at this time would have started from Therapia Lane.
