Yes - living in Banbury theres been rumours for ages along with a "scoping option" (dont really know what that is!) application to the council about 6 months ago for the depot.
A 'scoping opinion application' is used to give the council the general idea of the proposals and avoid the applicant wasting time on features of an application that are certain to fail.
In this case, it was used to get the council to decide if an environmental impact statement (EIS) was required, and also to define the limits of the area required to be addressed by the EIS.
The scoping application was available on the same website, it was there for the public to see all along. 6 months before that there was also a 'screening opinion' application, another initial application giving the general features. All three reports come up together after a search for 'maintenance depot' on the planning site's advance search option.

One significant point I hadn't fully noticed in the previous applications was that the new LMD actually replaces the existing 30 vehicle stabling sidings on the up side of the station, because they are lost when the layout changes with Banbury area re-signalling. That suggests quite a major change to the whole area if those sidings are to be replaced - it's only a few years since they were newly upgraded?
In general, that must mean that overnight stabling and cleaning activities will be further away from the local residential areas, in which case it must be good news for the people who objected to the noise last time...
