One of the E400s from EY was previously confirmed as being the spare for the X1 (6336 IIRC). One of the new E400 batch will therefore be going up to Consett for the X30 if I understood the update.

It'll be interesting to see what turns up first out of the E400s or StreetDecks. That should also determine the fleet number unless Dan has already assigned them so they stay in sync - i.e. new E400s being 6341 onwards before the StreetDecks are counted
