I am not sure what the fleet breakdown is specifically, however a Go North West ex London Enviro E400 was delivered during the week to Wigan and staff have been told that its being allocated their, also the loaned is a Go North East StreetDeck, has been at Wigan this week that is used for driver familiarisation, so presumably some StreetDecks will transfer from Bolton to Wigan, freed up by the large fleet of BYD/ADL City E400 going into Bolton. I still don't think there are enough saloons yet as it was reported previously somewhere the a batch of ADL E200MMC's was being transferred up for use at Wigan from Go South Coast but this doesn't yet appear to have happened and news on this has gone quite. Heywood depot is only temporary and is expected to close on 23rd September 2023 with staff, routes and vehicles moving to Bolton Weston Street which will have a run out of 192 vehicles and an allocation of 200+ vehicles. There are quoted as being 3 Volvo B5TL MCV for use on Vantage Services but so far only two have been repainted to Yellow. However I still reel there is a shortage of saloons especially for Wigan which plus Arriva routes to Chorley have a heavy saloon requirement currently, unless the 362 and 1-4 are being converted to decker?
In terms of Diamond a number of vehicles are being transferred in from around the group, as well as the remaining vehicles from Diamond North West that are not transferring to Go North West. Bolton Goodwin Street/Folds Road Allocation will be a number of ex FirstGroup Streetlites plus the existing training fleet as far as I am aware.
