The railway was one of several constructed to serve the intensive quarrying, mining and iron founding operations in the area west of Wrexham, which were undergoing considerable expansion in the mid 19th century thanks to exploitation of the underlying Middle
Coal Measures.
Construction The section of line between Brymbo and Minera had originally been part of the former
North Wales Mineral Railway, built in 1844 and later incorporated into the
Great Western Railway. This line's operation was constrained by the
rope-worked inclines, locally known as "brakes", and had two tunnels along its route through the hilly country between
Wheatsheaf Junction, near Wrexham, and Brymbo. As a result of the expanding traffic on the line and the bottleneck created by the inclines, an act of Parliament the
Wrexham and Minera Railway Act 1861 (
24 & 25 Vict. c. xxxii) proposed that a new railway, the Wrexham and Minera Railway, would be constructed from
Croes Newydd, at
Wrexham on the main
Shrewsbury-Chester line of the Great Western Railway to Brymbo, where it would join the GWR's existing route to Minera. The new railway company would have a capital of £48,000 in total (£36,000 of which would be in shares) and the power to enter into agreement with GWR on operational matters and division of receipts.
George Robert Jebb, who had previously worked on the Shrewsbury-Chester route, was appointed Resident Engineer. After 18 months construction the line was opened without ceremony on 22 May 1862. The new trackbed was dual track and joined the old single track formation just past Brymbo tunnel, thereby removing the use of both tunnels, the Brymbo tunnel was described as "delapidated". The new line involved the construction of twelve bridges, and a large area with six new sidings was provided at
Croes Newydd goods station which took over from Wheatsheaf station for invoicing traffic on the line. In June 1866 the line was jointly leased to the GWR and
LNWR, within whose "sphere of influence" it fell. A short branch was also constructed through to the colliery at
Vron, owned by William Low, one of the Wrexham and Minera company's directors. In the 1870s a further extension, the
Wrexham and Minera Joint Railway, was built from Brymbo through to an end-on connection with the LNWR's
Ffrith Branch, which ran from
Llanfynydd to
Coed Talon near
Mold. This line was jointly operated by the GWR and the LNWR - the only line in North Wales to be so operated. The completion of this link through the
Cegidog valley not only gave the GWR a route to Mold, but allowed the LNWR access to the
North Wales Coalfield. The construction of the Wrexham-Brymbo line led to the immediate abandonment of the North Wales Mineral Railway's original Brymbo (or "Brake") tunnel and incline. There was a successful application to use one end of the Brymbo tunnel to store explosives in 1872, in which it was stated that the centre of the tunnel had fallen in due to "undermining of the ground". The lower section of the NWMR route from Wheatsheaf Junction, through Summerhill Tunnel, to the collieries in the
Moss valley remained in use as the Wheat Sheaf and Ffrwd Branch until 1908.
Introduction of passenger services Between 1882 and 1905 the GWR gradually introduced passenger services between Wrexham and Minera, in response to requests from local communities. Halts or stations were located at Plas Power (
Southsea), the Lodge, Brymbo, Brymbo West, Pentresaeson (for
Bwlchgwyn),
Coedpoeth, and Vicarage Crossing (
Minera), with a passenger terminus at the rather remote Berwig Halt. From 1905 the GWR began operating a
railmotor service, with as many as fifteen workings on Saturdays. The LNWR ran its own passenger trains from Mold south to the joint station at Brymbo. In 1905, the businesses of
Coedpoeth campaigned for the
Great Western Railway company to lay a new branch from the existing Coedpoeth Station into the village centre. Local business claimed the station was too far away (being effectively located in
Minera) to serve them properly and was of little convenience. Regardless, their
petition failed miserably. This may have been because the gradient was simply too steep for conventional rail, as well as the little profit for a large undertaking. Despite this situation, Coedpoeth station remained a main focal point for the area, serving several villages with a combined population of around 9000 people. The end section of the Vron branch was closed in 1930 along with the collieries it served, but part of its length from Vron Junction remained in use to serve the increasing steelworks traffic. Passenger traffic on the joint line from Brymbo to Coed Talon declined during the
Second World War, however, with only two passenger trains a day in each direction, largely maintained for schoolchildren attending school in Mold. The gradients here could be problematic: there was an incident in the 1970s in which a train ran out of control on the former Vron Branch, and broke through level crossing gates in Brymbo.
Final closure By the early 1970s the section of line from Brymbo West to Minera saw only two trains a week, and it was closed in 1972, shortly before
Minera Limeworks was itself closed. The last part of the system, the 3-mile line from Brymbo West to Wrexham, remained open for freight trains to and from the steelworks, and as late as the mid 1970s there were seven return workings a day. This section of line was taken out of use on 1 October 1982, due to increasing amounts of steelworks traffic being sent by road. The steelworks itself closed in 1990–91, along with a final section of the Vron Branch that had remained in use as part of the works' internal railway system.
Today After a period of abandonment, the track was lifted in the late 1980s. Many of the line's bridges and other structures, including the platforms of the former Brymbo station, were not demolished until the 1990s. A number of structures remain, including a large stone
viaduct near
Ffrith on the former Joint Railway from Brymbo to Coed Talon. The
Moss Valley spur between
Wrexham Maelor Hospital and the site of Moss and Pentre Station has now been re-surfaced as a
cycle route. ==Wrexham, Mold and Connah's Quay Brymbo Branch==
