I think that if GNE get any deckers this year, they'll go with ADL. The ADL E400 MMC seems a far more solid product than either the Wright Streetdeck or Volvo B5TL Gemini 3 and when it comes to replacing the big three a few years down the line, then they've either got the option to stick with the Dennis Trident 2 chassis and have the Cummins ISBe unit setup to give better performance on the rural Tyne Valley Roads and Washington Highway or, go for the Scania N230UD Chassis on the E400 MMC bodywork but with the exception of the TTX, then the former option would be more than adequate.
BTW, my perception of the ADL E400 and E400 MMC both on the Dennis Trident 2 chassis has changed and the reason why I was put off them initially for was because of 7501 - 7513 at Ashington Depot. The newer batch from 7514 upwards seem a better batch and I think that they'd fit in well in GNE's fleet as the maintenance is of a good standard and GNE usually purchase 1 spare for every 7-8 vehicles purchased now.
