[1] The network commenced operations on 26 March 2006 with the introduction of Fastrack B between Temple Hill and Gravesend.

[8][9] On 23 August 2021, Fastrack AZ commenced operations in order to serve the Amazon LCY3 distribution centre in Dartford.

[10] The route was initially operated by Go-Coach but transferred to Arriva Southern Counties on 3 April 2022 with Fastrack A being modified to serve the LCY3 distribution centre at the same time.

[20][21] From 21 March to 9 May 2018, Fastrack took part in a trial scheme which saw an additional hourly journey made by an electric Volvo 7900e, with a main charging point installed in the form of a generator at the front of Greenhithe station allowing the bus to fully charge inside six minutes.

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.
