Surely there can’t be 38 E400s on loan from Cambridge plus the single deckers
The E400's are not on loan from Cambridge. They're officially allocated to Peterborough and most of the E200's have been there since new . 19699-703 and 36934/36 were transferred in from Bedford.
Cambridge now has all the former busway Scania E400's from Fenstanton after service revisions meant far less guidewheel fitted vehicles were needed. Only 12 deckers are now allocated to Fenstanton.

Bedford now has ex Cambridge, Fenstanton and Peterborough Darts 34535-38 and E200's 37210-12/14/15/30/31/34/35
