Tunnel Vision


Paxton (AKA Upper Norwood, Nunhead and Sydenham)

Nr Crystal Palace

London, SE26

Portals at TQ338712 and TQ341715

Researching Paxton Tunnel proved to be quite confusing because it has carried various names at various times. Originally named Paxton Tunnel to fete Joseph, the genius behind the cast iron structure of the Crystal Palace, it is referred to as Sydenham tunnel on the later rail maps of the South Eastern & Chatham Railway. To complicate matters, it is also known locally as both Upper Norwood or Nunhead.

This abstract is taken from the 1959 One Inch Ordnance Survey Map and shows both the southern Paxton tunnel and the northern Crescent Wood. The map is dated 1959, which is after the track has been lifted. It is still shown because the previous full revision was in 1954/5 and the 1959 map was just major corrections. The stations were accurately shown as closed but have been 'brought back to life' with a little recolouring in Photoshop.

 

The tunnel was built between the proposed site of Upper Sydenham station (built in 1884) in the North and the approach to Crystal Palace High Level (known as Crystal Palace High Level and Upper Norwood from 1898) in the south.

This 1956 photograph shows the approach to Crystal Palace High Level station complete with the station's northern signal box and the southern portal of the Paxton Tunnel in the background.

The 439-yard, double bore tunnel was constructed by the Crystal Palace and South London Junction Railway to serve the Great Exhibition when it moved (complete with the reconstructed Crystal Palace) from Hyde Park in 1852. The line opened to revenue earning services on the 1st August 1865.

This line carried trains from the immense caverns of Crystal Palace High Level Station, alongside Crystal Palace Parade, to the junction at Nunhead. The ruling gradient for the double track line throughout was 1 in 78 and this included the only two tunnels on the whole branch which were built very close together at either end of Upper Sydenham Station (the second being Crescent Wood Tunnel).

Electrification equipment was bought from 1910 onwards but he installation was sporadic and was not completed for a staggering 15 years in 1925.

The branch was never a great financial success as its route into London traced a path through picturesque, but sparsely populated areas of the garden suburbs. This lack of paying passengers led to the line being closed and reopened several times in its short life. The destruction of the Crystal Palace by fire in 1936 finally sealed the fate of the line and its decline from this point was inexolarable.

The line first closed between 1st January 1917 and 1st March, 1919. Then, towards the end of the war, it closed again on 22nd May 1944 until 4th March 1946.

After the second closure, it was often suggested that the Bakerloo Line could adopt the line of route for its long-planned extension into south London. The extension never went ahead, of course, and when the plans were abandoned the line finally closed on 20th September 1954.

The Situation in 2004

Although heavily built upon since its closure, the branch line is still easy to follow as large sections of it are now nature reserves, nature trails or public parks.

Both Paxton Tunnel and its northern sister, Crescent Wood, are securely sealed by heavy steel doors with secondary high fences erected in front of them (except the southern portal of Crescent Wood which lacks the fence).

These barriers were fitted when, over a very short period in the 1980s, several local children went missing and police dogs were used to search the tunnels. Residents' fears of the perceived danger (rather than any gruesome finds) prompted the council to seal all four portals, just leaving grilles at the very top open for ventilation to help slow the degradation of the bores.

Access

Both the northern and southern portals are easily accessible to visit today although access is impossible. Sub Brit is talking to Lewisham Council for permission to photograph the site and if we are successful, those photographs will appear here in due course.

The two mouths are situated in modern housing estates with good road access.

The nortern portal now stands forgotten at the back of a five-a-side pitch in Hill Crest Park. The line used to emerge from this tunnel and immediately go into a tight reverse curve (over Penge Tunnel) and then reverse again to go through Upper Sydenham Station where the platforms met the southern portal of Crescent Woods tunnel.

Note the profile of the tunnel in this shot and compare to the southern portal below. The grille at the top of the tunnel mouth is for ventilation and presumably to allow free access for bats.

The northern portal can be found just off of Westwood Hill. Turn into High Level Drive and follow the road round until you come to Gradient Drive on the left and turn into it. The tunnel mouth is easy to see behind the football pitch.at the end.


This shot along the length of Spinney Gardens shows the beautifull brickwork of the abutment which carries Crystal Palace Parade, the A212, above. Comparing this image to the old photograph at the top of the page we see that the photographer is standing just to the north of the signalbox and on the line of the two sidings which ran immediately under the abutment.

Note how the southern portal is wider that the northern. This change in profile is to accommodate both a curve where the running lines deviated west (left in this picture) into the throat of the High Level station to make space for two stabling sidings built between the running lines and the retaining wall.

The southern portal can be seen from above at the junction of Crystal Palace Parade and College Road. Access for a closer look can be gained from Farquahar Road, then into Bowley Lane, follow the small estate road round to the left and the portal lies at the far end.

Anomalies

During research on this project a strange anomaly has cropped up. The line opened in 1865 and although it should have been based on an actual survey, detailed perusal of the 1874 Ordnance Survey map clearly shows the northern portal as being in Sydenham Hill Woods and not where Upper Sydenham was built in 1884.

The northern entrance of Crescent Wood tunnel is in direct alignment with the Southern portal of Upper Norwood tunnel, which may, or may not, be relevant. Both are clearly shown on the map. A cartographer's mistake, perhaps?

Another noticeable feature of the two sister tunnels when considered together is that the two portals that face each other on either side of Upper Sydenham station both share the same design, as do the two 'outer' portals on each tunnel.
