Crossing, avoiding a congestion hotspot and allowing the original six-minute peak frequency to be improved to five minutes. On Monday, 10 December 2012 the Everards Link Phase 2, which links Greenhithe station with the Ingress Park housing development via a stretch of busway, opened. From Sunday, 2 September 2018 Fastrack B was rerouted within Ingress Park to serve the whole of the development following the completion of a new section of road linking the development with London Road. In August 2020, Fastrack B was rerouted again, between and Gravesend along the newly constructed Springhead Bridge so that buses now serve the Springhead Park development. From Sunday, 3 April 2022, Fastrack A was rerouted within Dartford to serve the Amazon LCY3 distribution centre, in place of Fastrack AZ which was modified to only operate at shift changeover times. A 24 hour service was introduced on Fastrack A at the same time, running between Dartford and Greenhithe Station. Fares and ticketing The network is split into three fare zones. Tickets are sold by the driver and from roadside machines, at certain bus stops, to allow for faster boarding. M-tickets, bus tickets on mobile phones, were successfully trialled on Monday, 11 February 2008 and are now available across the Arriva bus network.

On Sunday, 4 August 2019 Arriva Kent Thameside retained the contract to operate the Fastrack B service. As part of this, the 14 Wright StreetLites on the route were replaced with newer Alexander Dennis Enviro200 MMC vehicles transferred from the Medway area which were refurbished to Fastrack specification. 7 of the Wright StreetLites continue to operate on Fastrack A. Between Monday, 23 August 2021 and Sunday, 3 April 2022, whilst the Fastrack AZ service was operated by Go-Coach, a total of eight Alexander Dennis Enviro400 vehicles worked on the service.
