Title: A Prototypical Space Saving Idea called a Sliding Platform Bridge
Post by: Bob G on July 01, 2023, 09:07:47 AM
While perusing Flickr I came across this very wierd access arrangement onto a platform from a station building.

Can't imagine that it is still there!

The link is one photo out for me. Going back one finds it.

I assume that it is simply to move equipment in and out of the building, giving a flat and level route for it to be rolled on a trolley. A simple and effective solution.

Mea culpa. Indeed, I was looking at Motorail trains on the Southern.

Brockenhurst, between the parcels office and the platform, linked to the signal box to ensure it is not operated when the line is in use.

I'm pretty sure one of the East Suffolk line stations had a platform which could be swung across the lines for road access.

From what I read online some months back, the bridge is locked to the platform, and the rail removed by NR after maintenance.

I also came across a similar bridge on the internet recently, not something I've seen before. I wonder how common these were?

You'd want to be sure no expresses were due though when using it though!!
Anyone know where this was?

The East Suffolk line station with rotating platforms was Halesworth;

Other views if you Google Halesworth station.

Halesworth had a movable platform section, I believe it is still there albeit immobilised, it may even be listed, I think Lewes station has or had similar bridges over a disused platform bereft of track albeit not movable.

I think that may be Beccles, also in Suffolk.

Correct, Roy. Also on the East Suffolk line; this line is the one curving to the right, on the left was the platform and line to Beccles (Waveney Valley line).

Malton, on the York-Scarborough line, also had a slide-out bridge to connect the down platform (station entrance & booking office) with the otherwise isolated up platform. The bridge was, IIRC, interlocked with the signalbox.  The up platform has now been demolished and stopping trains in both directions use the old down platform.  (The up line is still in place for non-stop trains.)

i would imagine many members are aware of the procedure at Ventnor I o Wight staiton--( from wikepedia):

The station had a platform connected to the station buildings and a narrow island platform. There was only one track between the side platform and the island platform. When this track was occupied, an incoming train arrived at the outer face of the island platform and passengers had to pass through the train on the inner track. When this train then departed, a temporary bridge that was a former ship's gangway, as used on the Portsmouth to Ryde ferries was manually pushed across the intervening track to allow passenger access to the train on the outside of the island platform. Further away from the station buildings were goods sidings which mainly served coal merchants who operated from caves in the chalk sides of the station cutting.
