[3][4] In 1992, the local brands were dropped and Mainline became the standard fleetname across the company's operating area.

In 2000 First Mainline was rebranded as First South Yorkshire and the corporate light grey, blue and pink livery introduced.

[12] In September 2016, Steel Link X1 express route commenced operating from Sheffield to Maltby via the Bus Rapid Transit North scheme.

[17][needs update] Following the First South Yorkshire and Midlands merger in 2020, new liveries and brands were introduced for the First Sheffield and First Doncaster fleets.

The first to be introduced was Doncaster's Clever Buses in August 2020, utilising eight acquired Volvo B7RLE Wright Eclipse Urban buses on the 66 route in Doncaster, with the 'clever' aspect of the name referencing new contactless payment systems that were being introduced across the fleet.

First Doncaster's new livery follows a similar layout with red and cream with purple elements.

Having previously been contracted with refurbishing over 200 of London Buses' AEC Routemasters when operated by South Yorkshire Transport,[21] the engineering works of this depot was used as the FirstGroup's Commercial Unit following the company's purchase in 1998.

Buses and coaches across the group would be sent to the Midland Road works for refurbishment, repairs and repainting.
