Details are now emerging on delivery dates for the latest Trent Barton E200MMCs thanks to The Derby Bus Depot

The first batch due are the 11 bound for the 'Kinchbus' fleet to replace the Citaros on 'Skylink Derby' - these are due in the next few weeks and will enter service gradually. The Citaros will then go in the opposite direction to ADL for resale - a number are understood to have already been sold to Ipswich Buses.
The second batch will be 16 for 'rainbow 1' replacing 6 year old Optare Versa V1170s (the only examples of that length in the fleet) which will be redeployed within the Trent Barton fleet with rumours of 'the sixes' mentioned.

Reports suggest that some of the remaining 25 due in 2021 will be for Sutton depot for 'the threes' replacing what will be by then 9 year Optare Versas.
