ADL Enviro 400

33863 and 33864 were part of an order for 60 vehicles from Alexander Dennis that took the fleet numbers 33831 to 33890 and as they were new in the summer of 2014, they joined the First Games Fleet for use on the contract for transport First had for the Glasgow Commonwealth Games. After use on the Games contract the vehicles soon joined their intended operating unit of First South Yorkshire. The vehicles settled down normal service in South Yorkshire. With the introduction of new electric vehicles, the many of the existing fleet was surplus and has been cascaded to other first group companies. 33863 and 33864 arrived in the Worcester fleet over the weekend of the 20th and 21st March Both vehicles required very little preparation and entered service on Monday 22nd March. The most obvious change was the removal of the Sheffield fleet names. In the middle of July 2024 a further seven vehicles from the same batch moved from South Yorkshire to Worcester. During the first week of August 2024 sister vehicles 33859 and 33862 arrived at Worcester from Bath depot. With the arrival of 33861 on 13th August from Bath Worcester now has the whole batch from 33859 to 33870 made up of vehicles transferred from Sheffield and Bath depots.  Ironically the movement of the ADL 400s to Worcester was part of a plan to make the Worcester depot totally ADL vehicle operated. In moving the E400s from First West Yorkshire this meant that that this was the first time for 64 years that there had not been a Dennis or Alexander vehicle in that fleet.
