Locations

The railway runs along the east side of the A4085 from Betws Garmon station, crossing the Afon Gwyrfai. It passes under OB53 (A4085) at Ch 7180. The railway now remains to the west of the road behind the Water Works to the end of this section. The alignment passes through the Bryn Gloch caravan site, where a new overbridge (OB54) has been constructed. The route then climbs steeply to pass along the rear of the water treatment works to UB56. At the south end of the Water Works is the former junction with the Ystrad Isaf mine branch (active during WW1 but removed 1922). Finally the route crosses pastureland and recrosses the Afon Gwyrfai at Cae Hywel. The next section begins at Ch. 7900 just south of the Salem bridge.

The formation is clearly visible from the A4085 approaching OB53. There is a public footpath from Betws Garmon church along the east side of the river that gives an alternative view of this section. Another public footpath runs south through Bryn Gloch Caravan Park. Near the footbridge across the river the footpath splits in two and a section runs south alongside the trackbed at Ch. 7600 approx. before crossing it at LC31 to join the main road just south of the water treatment works.

 

Gradients 

The route runs level from Betws Garmon towards OB53 where there is small dip at 1 in 100 under the bridge. The railway climbs at 1 in 60 through the Bryn Gloch caravan site and then falls at 1 in 1500 towards the Afon Gwyrfai bridge UB56.

 

Afon Gwyrfai Bridge

From Betws Garmon station, the railway immediately crosses the Afon Gwyrfai on a bowstring girder bridge 15 metres long. This was removed on 2/11/00 and is now stored in Dinas North yard.

This northerly view (16/1/01) shows the completed concrete works for the Gwyrfai bridge in the distance and the flood relief channel UB52, nearer to the viewpoint as taken from the main road bridge. There is a slight bend to the right after UB52 so the further bridge is not square on to the nearer. In the distance, to the right of the blue containers, the rolled slate waste trackbed can be seen curving away from Betws Garmon station. Click on the image to enlarge.

When the tenders were placed for UB51, the quotes came in around 80,000, some 30,000 above expectations. As a result, it was decided to investigate redundant BR bridges and a set of old BR bridge girders of a suitable size was found on a site being cleared for redevelopment near Rotherham.

The bridge girders were altered to fit, shot blasted, painted in undercoat and delivered with a saving of 60,000 to the project. At the end of May, volunteers were painting the girders at Betws Garmon.

The bridge was first assembled on the north side of the river in Betws Garmon station. It was set up on wooden sleepers, aligned by laser and drawn together with temporary bolts. These are being replaced with High Strength Friction Grip (HSFG) bolts, which are, as the name suggests, quite special and are used in bridge construction to make a shake proof and robust connection. The bolts will fail prematurely if the threads are damaged, and they cannot be repeatedly tightened, loosened and tightened again.

This northerly view (18/5/03) shows the bridge erected at the south end of Betws Garmon station. Work was nearing completion on the first coat of epoxy grey paint.

Prior to fitting together, it was not known what tolerances the members had been fabricated to, and whether affected by rust, deformation of the mating surfaces, or misalignment of the holes. Usually these factors result in a lot of jiggling of the girders to get all 48 bolts to fit simultaneously and some bolts are tight while others require longer bolts to draw the mating surfaces together with force. Thus to avoid damage, cheaper, readily obtainable bolts are used for fitting together.

These will be replaced one at a time with HSFG bolts to make the permanent connection. The two types cannot be confused because they have different markings and have different size heads. To make absolutely sure, the temporary bolts have been fitted in reverse with the nuts on the outside, so at a glance it will be easy to ascertain when they have all been changed.

In the event, all of the bolts fitted easily. The holes are 15/16 inches and the bolts should be 7/8 in; dimensions being in accordance with the old imperial standards used by BR when the girders were constructed. Imperial size HSFG bolts are no longer available, so the WHLR had to use the nearest metric size, which is 22mm, albeit 2% smaller in area. Even 22mm bolts are non-preferred and took some time to obtain.

In the last week of May, the bridge was to receive its final epoxy grey coat and the waybeams and walkways were to be fitted. The bridge was to be lifted onto the abutments week ending 6/6/03.

Flood relief bridge UB52 

The railway runs across the floodplain on a 2 metre high embankment before crossing a flood relief bridge, UB52.

A plant road has been built from the A4085 gate at the location shown below, across the overflow channel to access the trackbed between UB52 (spillway) and UB51, the removed bowstring bridge.

When Triact examined the flood relief bridge they found a major problem. The bridge had no proper foundations and the slate slab deck merely distributed the rolling weight of the loco over the six piers founded in boggy marsh. The structure was not up to modern standards and the solution was to build two new concrete piers either end and float a concrete beam over the central four piers. This would allow the bridge to retain its appearance, though the central four piers would only have a cosmetic role.

A4085 Bridge (OB53)

The railway passes under the A4085 at this point in an unusual bridge with a flat deck beam and galvanised steel sheeting sides.

In a recent change, GCC has advised the WHLR that it is to rebuild OB53 to improve the weight restricted bridge. Any widening would require the abutments to be lengthened along the railway alignment by a proportionate amount. The form of the rebuild has not yet been advised.

A new cast concrete deck is to be provided reducing the current weight restriction upon the bridge. GCC has already re-pointed the Castell Cidwm bridge OB71 and the Pitt's Head bridge OB123 last Autumn. The idea is to get the work done on OB53 before the railway opens in Summer 2002, thus causing less disruption.

Gwynedd Council is widening the bridge on the north side which will include the ramps. The existing abutments are being lengthened at the same width as perceived from the railway track. GCC is to use the existing 'De Winton' cast iron beams under the parapet of the widened bridge.  The parapet will be stone clad and conform to current day standards. The existing deck of cast iron beams with brick arches between them (jack arches) will be replaced by a reinforced concrete deck. In these circumstances the two end cast iron beams will become decorative only.

Work started on 22/10/01 and will take several months. It is likely to be finished in September 2002. The WHLR reached agreement with Gwynedd Structures (GCC) with regard to taking 60 foot articulated rail carrying lorries over OB53 at Bryn Gloch. This weak bridge had a 17 tonne weight limit restriction added from May 2001. Rather than take full loads of 33 rails (19.8 tonnes net), the WHLR will be taking 22 rails max giving an axle load acceptable to Gwynedd Structures. Ballast for the tracklaying at Rhyd Ddu came from Penmaenmawr, being 55p/tonne more expensive to go the long way round, missing the 17 tonne weight limit until the bridge was completed in Summer 2002.

This southerly view (30/10/02) of the trackbed just north of OB53 shows the graded formation with slate fines dipping under the bridge. This led to an accumulation of water during the Autumn that will only be remedied when a deep drain is cut through the bridge slot. The water will then drain to the ditch to the left.

GCC contractors were on site in early December removing the recently erected cladding on the west abutment, which found to be slightly foul of the new wider loading gauge. This was soon put right with thinner cladding blocks. Attention must then have switched to draining the site and on 23/12/02 a contractor was tidying up the landscaping north of the bridge and the dip under the bridge was completely dry.

This will permit the ballasting to go ahead to the end of the formation at Bryn Gloch. Ballasting should follow promptly during January 2003 and this should permit tracklaying over the short gap from Ch.7240 at Bryn Gloch to Betws Garmon bridge at Ch.7000.

 

S3-406.JPG (70884 bytes)

This southerly archive view shows the detail of the decaying metalwork of OB53. The jack arch (brick arches on cast iron beams) structure supporting the roadway is weak and the bridge had a 17.5 weight limit imposed on it in May. GCC intends rebuilding the bridge this Autumn, to be completed within six months. The de Winton girders under the parapets will be retained for decorative purposes only. The bridge height may be just sufficient for the WHR loading gauge but the opportunity may be taken to raise it a little to avoid the need to underpin the foundations. Click on the image to enlarge.

By March, Jones Bros was on site adding a deep drain through the bridge and adding re-inforced concrete haunches to support the abutments of the original section of the bridge. A reinforced concrete base braces the abutments. Jones Bros. cleared the site by mid-May.

Although the roadway aspects of the bridge were completed and opened in early July, cladding dragged on slowly until September. The WHLR had to wait for the site to be released so they could finish the short section of trackbed through the bridge. Jones Bros. started ballasting south of the bridge from 2/8/02. Ballasting could be completed from a dump at UB52 from Bryn Gloch back through OB53 to UB52 and rail extended north from OB54.

Water Main diversion

Although Triact has been on site since October, and has removed the bowstring bridge, it cannot start work south of UB52 until Hyder (Welsh Water) moves the Caernarfon Water Main off the trackbed. The main was only placed on the trackbed in 1995 when it was still uncertain that the WHR project would go ahead.

Work started on the water main on 15/2/01 with a site being prepared next to the graveyard for pipe storage. Hyder has appointed Laing as its Project Managers though a local contractor, Mulcair, was called in to do the work on the ground.

On 19/2/01, a deep trench was dug parallel to the trackbed and some 20 metres to the east for the new pipe run. The pipe had been laid and the trench had been backfilled by 7/4/01.

By the end of June, work was focussed on diverting the pipe diagonally across the main road between the entrance to the graveyard and the Bryn Gloch footpath. In July, work carried through Bryn Gloch to the boundary of the Waterworks. The trench was rapidly re-turfed so that the campsite would not lose trade.

The pipeline pit shuttering adjacent to the south abutment of UB51 was removed by mid August. It had been necessary to join the pipes and it appeared that all the pipeline works were complete.

This southerly view (23/2/02) shows the work taking place at OB54 from OB53. On this date the felled trees on this section had still to be cleared. An unusually wide strip of land between the two, some 100m long, has been suggested by some as the location for a future halt but a 'borrow pit' to the right has left a trench to be filled.

While the bridge works are taking place a temporary parallel scaffold footbridge is being used on the south side as was in use for a period during the Cae Moel river diversion (Phase2). The new footbridge was constructed in early November and in use by November 11th.

Progress was made with undergrowth clearance of the trackbed on the southern (Bryn Gloch) side of the bridge and by 9/2/02, all trees on the trackbed had been cut down ahead of the bird nesting season when tree felling is prohibited.

Traffic control was in operation, with removal of the old roadside walls underway. The scaffold bridge allowed a view of the southern face of OB53, largely invisible for many years. Traffic control persisted for some time as the deck beams of OB53 are removed during the Spring and replaced by concrete beams.

Bryn Gloch

The trackbed is overgrown initially and then crosses between the caravan park and Bryn Gloch club house. A new bridge is to be constructed here at Ch. 7300 with the design sufficient to allow caravans to cross. Strangely, the owner has rejected the suggestion of a halt here despite the obvious business it would bring. Apparently, the owner wants the railway hedged in throughout his caravan site so that it cannot be seen!

Work was due to start on 1/11/01 but Triact found they were over-committed and so the WHLR appointed Jones Bros. of Ruthin instead. Jones Bros. did much of Phase 2 trackbed work. The work started on 7/1/02 and is proceeding north from Jones Bros. base at the north end of Cae Hywel bridge from a worksite known as Tros-y-Gol.

The first job was clearance of fly-tipping, which had taken place on the trackbed by persons unknown until late last year. Vegetation was cleared including cutting down 60 years of tree growth ahead of the bird nesting season, when there is a closed season on tree felling. The trackbed south from OB54 through the Bryn Gloch campsite was then consolidated with quarry waste. Previous stone supplies have been trucked in from Dorothea quarry in Nantlle.

Work on the new caravan site bridge was  underway in mid February. The excavations for the both abutment footings were excavated by 17/2/01. The caravan site access road was diverted to north of the old OB54 and the western ramp of the old bridge was excavated prior to demolition.

The 1m wide fenced slot for the footpath along the back of the Waterworks has been re-located. The original plan was to deviate the footpath at the old tramway junction, crossing onto Bryn Gloch campsite. However, the Water Authority has given up some of its land for the footpath. Consequently, LC31 moves back to its original position from Ch.7630 to Ch.7530, which is the position of the old A-frame rail-built stiles. These were removed to Dinas by 9/2/02.

The resulting 100m stretch of footpath parallels the railway and will provide interesting photographic locations, especially if Bryn Gloch Halt is eventually constructed between Ch.7300 and Ch.7500 as originally proposed.

This southerly view (11/8/02), just north of Cae Hywel bridge (UB56), shows the rail stack at Tros-y-gol worksite. Two lengths of temporary track lie alongside the rail stack to ease transfer to RRMs. The alignment is temporarily diverted around the stack and should make a straight line to the bridge in the background.

UB56 Cae Hywel bridge

This bridge is a similar bowstring girder and has been left in place as a local resident is using it rather than the adjacent ford to the west. It is currently planked across its full width. WHLR consulting engineers Posford Duvivier examined if the existing structure and weak abutments could be retained economically.

One previously proposed system was more sophisticated than rods through the structure with plates at the ends.  It involved coring through the structure or into the structure and inserting an impermeable fabric stocking which would then inflated with a chemical grout so that the hole and most of the adjacent voids were filled.

A reinforcing rod could also be installed and subsequently tensioned if required. The bolt end could be recessed into the stone work and the hole plugged with a stone core.

The advantage of the system would be that it helped to glue the structure together and spread the loads rather than creating point loadings. The grout would be contained and the tendency for pressure grouting to force the structure apart in an uncontrolled fashion eliminated.

However, a new bridge is to be constructed and the existing bridge girders will be reused on new re-inforced concrete abutments, clad with local stone. It appears that an improved overflow channel will be constructed on the south side. The bridge deck was lifted out in November and stored at Cae Hywel awaiting new steelwork cross members.

Access to the trackbed south from here is now via the adjacent low lying pipe bridge that becomes a ford when the river floods.

This southerly archive view shows UB56, the Gwyrfai Bridge, where the railway crosses from the east to the west bank. The bridge is a bowstring girder structure like the one recently removed from Betws Garmon. A further bridge of the same type is in situ at Plasynant Halt about 1 km south of this location.

Full details of the refurbishment of this bridge will be found on the next page.
