BDQ meaning in Governmental ?

Bradford Forster Square railway station serves Bradford, West Yorkshire, England. The majority of services to/from the railway station use Class 333 electrified trains operated by Northern Trains, on the Airedale Line to Skipton, the Wharfedale Line to Ilkley and the Leeds-Bradford Line to Leeds.

The other main railway station in the city is Bradford Interchange, about 10 minutes on foot from Forster Square, from where services operate along the Caldervale Line to Leeds, Halifax, Huddersfield, Manchester Victoria, Blackpool and London King's Cross. Bradford Interchange is situated at a higher level, across the city centre, than Forster Square. The Bradford Crossrail proposal to link the two stations is currently viewed as unlikely to proceed.
