Internal Condition
Internally wet in places, though not in any way flooded, nor very muddy. There are two ventilation shafts, both of which have been sealed and capped. The lining of these shafts lays in a heap below on the tunnel floor. The tunnel has been strengthened in two places for a short stretch of around 20-yards, one place about two thirds of the way from the southwestern post and the other close to the northeastern portal. The northeastern portal has been infilled, by piling up mud and rubble about 11 yards into the tunnel. Could not ascertain whether it had also been bricked up from the outside.
 
Access
Reach south-western portal via Queensbury Station site along track bed. This portal has been bricked-up with an opening door, which was not locked when visited.
This portal has been almost smothered by infilling and now lies in a deep and precipitous abyss surrounded by infill.
The north eastern portal was not found and I believe it now lies somewhere on the edge of a large new housing development, close to Oakleigh Avenue, which is off Station Road, Clayton. See E-mail on the North eastern portal : 02/10/05 Below.
Access to the west portal easy, along trackbed from the site of Queensbury Station, reached by a footpath from the huge skew railway bridge, which crosses the steeply inclined Brow Lane, or from another path off Bridle Stile Lane.

Date of last visit, inspection or update
Southwestern portal visited and entered by Nigel Callaghan & Andrew King on Wednesday 28th April 2004, and the tunnel was walked through right up to the infill, on 23rd July 2004 by the same people.
 
Notes & other points of interest
The approach to the western portal has been in filled with enormous quantities of inert waste, filling the approach to a height of about 35-ft above trackbed level. The portal of the tunnel is now engulfed in an abyss around 35-ft deep to within 50 yards of its portal. If further landfill material is dumped here the tunnels southwestern mouth will be entirely obliterated.

Comments
These routes abound in extensive earthworks, viaducts and tunnels, including the short branch to Bradford, City Road, Goods Deport and the branch to Halifax. The most notable being Lees Moor (1,533 yards) between Ingrow and Cullingworth on the Keighley section, Clayton (1,057 yards) between Queensbury and Clayton on the Bradford side of the longest tunnel on the system.
Sadly, the entire area of the historic and unusual triangular Queensbury Station has been bulldozed and totally destroyed; many of the approach cuttings to the tunnels have been in filled with waste and levelled. Anyone wishing to visit and view this interesting and unique site should do so without haste before it is totally destroyed forever.
 
Walking through the tunnel from the southwestern portal, it is straight and almost clear of any debris or rubbish. There are a few piles of old rotting sleepers and the tunnel is damp with a few drips of water. There are a few deep open drains in the centre of the tunnel and care must be taken not to fall into these. Both of the shafts have been sealed and a pile of bricks from their linings lays on the tracked below. At the northeastern end, a huge amount of clay, mud and rubble has been bulldozed against the tunnels mouth making entry or exit impossible and we had to exit by making the return walk back to the souteastern portal, facing a steep climb out.

File 1 Clayton aerial view (Google earth)
“CLAYTON-AERIAL” is an image composited using Google Earth. As you may know, this software allows you to view aerial shots of almost anywhere in the world. It also has a measuring tool. Using it, it’s possible to measure 1,057 yards from the visible south-west portal. This is shown by the yellow line.
The capped shafts which Adam Carter photographed are also shown on the photo.


To allow for any inaccuracy, I suspect the north-east portal could be anywhere within the blue circle.
The layout of the houses supports this. Two rows built either side of the tunnel line (Oakleigh Avenue and Rosehip Rise/Blackberry Way) which move further apart close to the portal. Their gardens are over the tunnel itself together with what appear to be lock-ups on top of the actual portal. There is then a house on Bramble Close, in the middle of the former trackbed.
