the 19 Euro 5 Enviro 200 MK1s due next month for South Sheilds will replace older 61 Reg Enviro 200 36461-79 which will transfer to Hartlepool to replace the 19 Transbus Darts
33401, 34561-69 and 34605-08 to Disposal or Reserve

The 19 new E200s for shields will not replace the MAN 14.240 Enviro 200s 39701-14 as there is only 14 of them, These will stay at Sheilds
Also 14 Reg 37143/44 will stay at Sheilds with one replacing 22734s role with 22734 going to disposal

MAN 18.220 ALX300s 22050/67/70 will stay aswell as Darts 35190/91/92/93/94/95

So anyone wanting one final ride/photo of 22734 you have just under 1 month left.

This was just pure guessing but all of it adds up so id say its 90% likely to happen.
