Welsh Highland (1923), North Devon and Cornwall Junction Light Railway (1925)To address Mcr Warrior in post #12, I am alright with including railways built in the 20th century which were then closed.
Anyway, it seems as though most of the railways that opened or were built in the 20th century were before 1920 (pre big four) or after 1980 (post Beeching) so I am ideally looking for those between those two dates but its fine if no one can find it.
The Liverpool Loop via Lime Street and Link (Exchange/Moorfields to Liverpool Central) certainly count.I don't know if it counts as a "new railway" but BR did a major rearrangement in the liverpool area to reduce the number of terminus stations and create what is now merseyrail.
In similar vein, the Southern Heights Light Railway between Orpington and Sanderstead was authorised in 1928, but ultimately not constructed. In this case, interest faded away during the 1930s following the death of Col Stephens, who was the line's main promoter. It was in preparation for this route that the line to Sanderstead via Woodside was electrified.GWR Westbury and Frome bypasses, 1930s. Southern Railway Chessington branch, 1939. Earthworks started for continuation of this to Leatherhead but abandoned due to WW2, afterwards the introduction of the Green Belt around London stopped further suburban development there.
Opened 1915, and closed post WW2, I believe. Was it (the Spurn Head railway) ever rail connected to the rest of the GB network?The isolated Spurn Point railway - possibly related to WW1?
If we can have resurrections, then the Mawddwy railway was closed in 1908 due to the state of the track but rebuilt in 1911 by the CambrianAlthough originally constructed in the 1860s and closed in 1880, the Potteries, Shrewsbury and North Wales was resuscitated as the Shropshire and Montgomeryshire not once but twice in the 20th century. Col Stephens reopened the line in 1911 and, after closure to passengers in 1933, was rebuilt by the War Department in 1941. If not new, at least born again!
Fishguard Harbour surely!GWR extended the line from Clarbeston Road through to the new Pembroke Dock station, to connect with the new steamers to Rosslare, sailing from the newly enlarged harbour. It fully opened in 1906, incorporating over 10 miles of new track.
Another nearby extension was the two and a half mile branch line to the new Royal Naval Armaments Depot at Trecwn, built in 1938. There were 58 storage tunnels hewn out of the rock, most had narrow gauge railway access. There were miles of narrow gauge around this extensive site. I was part of a guided tour around the site about 20 years ago....fascinating!
There were quite a number of 1960s low-volume freight connections built between adjacent lines. Radstock in Somerset connected the S&D to the adjacent ex-GWR Frome line to allow continued access to a colliery on the former. Like many such, it only lasted a few years before the whole set was closed.Post-Beeching, new connections were built at Cleckheaton (to connect a freight site on a closed line to a parallel open one) and I think something similar at Lenwade for the concrete products site? Not sure these were the only connections made to allow partial closure of routes.
Yes. Mid 1900s? Fishguard Harbour station opened 1906.Fishguard Harbour surely!
No, it was quite an extensive new construction from Clarbeston Road on the Haverfordwest line. along the Cleddau valley and northwards towards Fishguard, until it met the "old" line to Fishguard, which had turned off previously at Clynderwen, a winding and lightly-laid single track quite unsuited to main line express boat trains. The remaining shared bit was doubled, and, as you describe, finally extended the half mile to the new harbour. All still in use, of course. The "old" line continued for a while, but has long gone.Yes. Mid 1900s? Fishguard Harbour station opened 1906.
What are we talking about? Half a mile or so of track?
No rail crossing at Dornoch. There was a campaign for the new road bridge to be combined with a rail bridge, but it failed.Dornoch bridge
