Back on to my complex and fragmentary sequence of posts about the history of the complex and fragmentary South Wales railway network. It was prompted by news that Network Rail are working on upgrading the Ebbw Vale line to allow a better train frequency than once per hour, by widening the line from one track to two for a few miles around Aberbeeg. Changing the track, though, involves changing the signalling, and changing the signalling will involve getting rid of a little island of 19^th-century mechanical signalling that still exists in Casnewydd/Newport. It’s the signalbox at Park Junction, in the Gaer area of the city.

And there it is, with the signals pulled off for an Ebbw Vale train. This picture is from April 2021. It might not look like much from this angle, but if I swing round a bit, you can see that the box is really quite a grand affair for something that only handles a few trains per hour.

You’d be right to assume that, given the size of the building, it was built to control a much bigger junction than the handful of tracks in front of it today.

I’ve written before about the Monmouthshire Canal Company building a railway all the way back in 1805, to carry coal and iron down the Sirhowy Valley. This is, indeed, on that 1805 route. When, a few decades later, the South Wales Railway was built from Abertawe/Swansea to Casgwent/Chepstow, it burrowed under the Monmouthshire Canal Company’s railway at right-angles, and a complex mesh of interconnecting routes slowly developed. This is a map from around the time of the First World War, after the MCC and SWR had both been bought out by the Great Western, so confusingly both railways are in the same colour.

The Monmouthshire Canal’s railway runs from left to right, the South Wales Railway from bottom to top, and Park Junction is there on the left. Nowadays, most of the tangle of lines heading towards the docks has gone, and Park Junction is at one corner of a triangle, trains to Cardiff joining the main line at Ebbw Junction and those into Newport joining it at Gaer Junction.

I’ve written previously about that purple line running parallel to the yellow one. That belonged to the company which had extended Newport Docks, the Alexandra (Newport) Dock & Railway Company; and they had built a line from Bassaleg, right alongside the Great Western, so that coal trains coming down the Brecon & Merthyr Railway from Bargoed, Rhymney or Bedwas could reach Newport Docks without paying tolls to the GWR. When they were built, the lines ran around the back of the signalbox, which had nothing at all to do with them. You can see this on a more detailed map from around the same time.

I’ve made that one a clickthrough because it’s quite detailed; apologies for the horizontal line, but the original is split across two sheets which I’ve roughly stitched together. Three pairs of tracks in front of the box, belonging to the Great Western; and the pair behind it, separate, spreading out into a bank of sidings. About five years after this was surveyed, the Railways Act 1921 merged Newport Docks into the GWR, and within a few years they had put in additional connections at Park Junction, between the lines in front of the box and those that ran behind it.

Look how much suburbia has grown up in those twenty years, too.

The route through Park Junction lost its passenger services in the early 1960s. Ostensibly this was because British Railways wanted to rearrange the platforms at Newport Station in such a way that there was no space for the Ebbw and Sirhowy Valleys services to turn around; of course, if they had really cared about keeping them, they would have been able to find a way to do it. Back then, there was still heavy freight traffic up and down the valley, from the steel works and the mines; and a large marshalling yard at Rogerstone. Over the following years that traffic dwindled away and shrank, but Park Junction signalbox nevertheless survived, opening a bit less maybe, but still there to signal freight trains up the valley when needed. In the 2000s when the line to Ebbw Vale reopened to passengers, a modern signalling panel was put into one corner of the box to control most of the Ebbw Vale line; but the box still kept its mechanical levers and the tracks past it kept their mechanical semaphore signals, as you can see on the photos above.

Now, in 2022, Park Junction is something of an isolated island given that the main line through Newport is all controlled from the Wales Rail Operating Centre, in Cardiff. When passenger services returned to Ebbw Vale, only one track was kept north of Crosskeys, meaning that the maximum service frequency on the branch is the hour that it takes a train to get from Crosskeys to Ebbw Vale and back down to Crosskeys again. To increase the service means more track; more track means more points and signals; and if you’re putting in more points and signals, it makes sense to move on with the plan to put all of Wales’s signalling into the ROC. So, Park Junction will close, some time over the course of the next few months. It’s a shame, but that’s modernisation for you. I must try to get there again to take more photographs before it goes.

Last week, I posted a little bit about the history of the railway junction at Pye Corner, just outside Casnewydd/Newport. There, the original route of the horse-drawn tramway opened around 1805 is now a quiet, grassy back alleyway, with the railway that replaced it a few yards away. That railway line, now just a single-track branch, strides over the road into Bassaleg with a complex series of three parallel railway bridges, imposing and monolithic.

Looking through the tunnel of bridges, you can just about in this picture make out three different ones. In the middle, a stone arch. Beyond it a steel girder bridge and this side of it an arch in blue engineering brick. Three separate phases.

The stone arch is, I presume, the mid-19th-century bridge built by the Monmouthshire Canal Company when the railway line was rerouted from the back alleyway route it formerly took. On the far side: where the bridge was widened by the Great Western Railway, circa 1910 or so, to broaden the line up to Rhisga from two to four tracks. The blue engineering bricks on the nearside? Ostensibly that’s straightforward too—but not as straightforward as I first thought.

I mentioned in the previous post that Pye Corner was a railway junction as early as 1825, when the Rumney Railway was built from Pye Corner up to Rhymney. Now, I’ve said before that the railways of South Wales are complex and confusing, and the Rumney Railway is a case in point. Back in, say, 1860, there were two railways with very similar names, both linking Rhymney to the coast.

The Rumney Railway was the first, built around 1825, and like the Monmouthshire Canal Company’s railway it was horse-drawn, for its first few years. As you might expect from the name, it served Cwm Rhymni, running down from New Tredegar^* along the east bank of Afon Rhymni. Unlike most of the valleys of South Wales, Cwm Rhymni doesn’t take a particularly straight line from mountains to sea, and the Rumney Railway followed the river where it takes a sharp eastwards turn at Bedwas and flows through Machen. From there, the river takes a rambling, meandering route through rolling countryside, past Ruperra Castle and down to the sea just east of Caerdydd/Cardiff. The railway, on the other hand, cut across the narrow neck of land separating Afon Rhymni from Afon Ebwy, to reach the latter at Rhiwderin, and ending by joining the Monmouthshire Canal Company’s railway about a mile further on. How it crossed the Afon Ebwy to get there will be the subject of a later installment.

The confusion arises from the Rhymney Railway, which came along in the 1850s partly because the Rumney Railway (also sometimes known as the “Old Rumney”) was by the time it turned 30 already something of a wheezing, antiquated and outdated little line, upgraded to steam but still using horse-era track. The Rhymney Railway was built to give Cwm Rhymni a proper, modern railway, and it doesn’t really concern us here save to say that it didn’t stick with the river as the Rumney Railway did: it headed into Caerffili town centre, then burrowed southwards through the hills into Caerdydd with a tunnel over a mile long. The Rumney Railway’s owners were worried they were getting left behind but didn’t have the money to upgrade their line; within five years of the Rhymney Railway opening, they had sold the older line to the Brecon & Merthyr Railway, so that the latter railway could use it as a stepping-stone to reach the sea. They did have the money in the bank to rebuild the Rumney Railway in a modern fashion, and did so, building further connections from Machen to Caerffili.

This doesn’t explain where that brick-built bridge comes from, though. Here’s a map of the railway connections around Pye Corner circa 1914. This is from the Railway Clearing House junction diagrams, which were made to give definitive plans of where railways interconnected and what the distances between junctions were, in order to be able to work out per-mile traffic rates.

Yellow is the Great Western Railway (the former canal company line), blue is the Brecon & Merthyr, and you can see both companies have their Bassaleg stations. What’s the purple line though? That belonged to the company which owned the local docks, the grandly-named Alexandra (Newport & South Wales) Docks & Railway, or AND&R to its friends. They had wanted the collieries of Cwm Rhymni to be able to get their coal to the docks of Casnewydd, without having to pay any additional charges to the Great Western Railway; so they built a line parallel to the Great Western’s tracks between Pye Corner and Mendalgief, enabling coal trains to come straight off the Brecon & Merthyr and onto the dock company’s own line of route without touching the Great Western.

So that’s who built that imposing blue-brick bridge? Well, maybe. There’s certainly a boundary post still in the ground nearby, marking this off as AND&R land.

That answers the question, surely? Well, maybe not. We haven’t really looked at all of the evidence yet. However, as this post is already getting rather long, the conclusion (insofar as there is one) is sadly going to have to wait for another day.

* I’m not entirely sure where its original top terminus is. The Rumney Railway is particularly poorly-documented, so I’m not sure anyone is entirely sure quite where its original top terminus was.
