King's Lynn
The bridges of South Lynn
& Harbour Junction

Welcome to Norfolks disused railways coverage of the bridges and the Sugar-beet railway line remains at South Lynn on the outskirts of King's Lynn in Norfolk.

There are three Bridges still to this day, one Railway bank, and maybe a buttress in the overgrowth where a bridge once laid on top; also found were some leftover railway parts I discovered close to the old site of South Lynn station.

Bridge one was the bridge that linked up the M&gn line from South Lynn to London Liverpool Street. Now the trains serve London King's Cross on the fen line via a Harbour junction.

The second was the M&gn bridge that took the M&gn from South Lynn station over the River Nar.

The third bridge was built many years after the M&gn and the South Lynn railway station had closed.

This was used to take the Saddlebow industrial estate traffic over the old railway line used for the Sugar-beet factory at King's Lynn; the factory seemed to have been opened in 1927 and closed in 1997.

Bridge number four no longer exists. All that remains is the bank on one side and maybe the bridge abutments in the overgrowth where the M&gn crossed over the top of the Fen line before heading off towards Gayton Road station.

This bridge was demolished in a cab ride film I watched from 1989.

It shows that the banks and the bridge abutments were not overgrown in 1989

Also, the bank on the other side of the railway no longer exists as it's now an industrial site. Also, in the cab ride film from 1989, the harbour junction was still in use, and the double-lined railway had been made into a single line with the points still laid down where the track was once at this point double-lined.

Also, just after the Harbour Junction, a small, short-lived railway served Campbell's factory that has now been demolished and replaced with a supermarket.

Campbell's factory closed down in 2007 

When did the railway close down?

In the 1989 cab ride film I watched, the Campbells line was still in use.

When did the beet line close? Researching on the internet when the fen line was electrified in 1992, Was Harbour complete junction was taken up.

Please feel free to send me a message or a Tweet.



King's Lynn Harbour junction

The map below, with thanks to the National Library of Scotland, shows Harbour junction dated from 1949-1971

The map shows the line linking the central station from King's Lynn to South Lynn station on the M&gn.

The map below also shows the position of the four bridges.

King's Lynn Harbour Junction when the junction was still in use.

We see a diesel London Liverpool Street to King's Lynn train approaching the Harbour junction.

You can make out to the Right of the picture the harbour Junction that took trains off of the central King's Lynn to London Liverpool Street line and & off towards the M&GNJR South Lynn station that closed in 1959

The Harbour Junction seen here would have crossed one of the bridges we will cover down the page.

When this picture was taken, the M&gn would have been long closed, and the line would have only been freight use as far as the sugar beef factory.

Also seen in the picture here is that line is still double-tracked.

Thanks, Mark.

I found this picture with the help of the King's Lynn and area Model by J T Colquhoun's Facebook page.

This shows the Harbour junction at King's Lynn with a class 37 passing the junction signal box heading towards Watlington from King's Lynn.

The Class 37 looks to be carrying silica sand, so I am guessing it's a service from Middleton Towers quarry.

Middleton Towers freight trains use the old King's Lynn to Dereham line that remained open as far as Middleton Towers for freight use and is still used to this day when this page was published in 2022


Harbour junction to South Lynn link Bridge 

Here is the Old bridge as it stood in 2020 that linked up the M&gnjr from South Lynn to King's Lynn town Station.

This bridge would have served many different purposes in its life. Not only did it act as a link between both of King's Lynn's Stations,

But it would have also taken trains from the North & The Midlands Towards Hunstanton on Express day excursion trains.

In its last days, this old bridge was used as a shuttle line from the old British sugar factory that has now closed down and been demolished.

The sugar beet factory stood roughly where Palm paper now stands.

South Lynn M&gnjr Bridge Crossing 

This bridge took the M&gnjr from South Lynn to Fakenham, with Gayton Road being the next stop. 

The line went off after Fakenham & to many other destinations across Norfolk, including Great Yarmouth Sheringham Cromer & Norwich via Melton Constable.

This closed Bridge was photographed in 2020 from the Nar ​Valley way walk.


The third bridge

And the

Sugar beet factory

The maps below, once ae

Thanks once again to the National Library of Scotland, we see the Sugar Beet factory and the railway line that linked up the factory sidings up to the M&gn at South Lynn.

Once the M&gn closed, the factory's railway was kept open for a short while for freight use.

This third bridge is quite a new bridge and was built to take the factory's railway line under the Saddlebow estate access road.

This bridge, I'm guessing, was built during the construction of the A47 dual carriageway that's partly built over the South Lynn station site.

This third bridge was sited just after where south Lynn Station was but was not built during the M&gnr days and was built long after the closure for the sugar beet factory line to pass underneath saddlebow road.

Thanks again


Here we see the Saddlebow bridge taken in winter 2022


These two pictures of some old railway track left behind were found at the now grain silo site on the saddlebow industrial estate and were most likely left behind from what looks like some sidings from the M&gn at South Lynn.

At first, I thought they were from the sugar beet factory, but looking at old maps, the factory was far from where the siding were.

The sidings in the map below are where the grain silos now sit.


This is where I found this old railway track remaining whilst delivering on-site.


Until I went onsite to the silos, I never knew these railway tracks were there, so it was a nice pleasant surprise. 

Thanks again to the National Library of Scotland.

Anyone interested in railway history should take a look at this fantastic Page.
