The valve shafts at Loch Treig with the course of the Upper Works Railway evident as the curving embankment on the left .........

where in the early 1990's, this wagon stood as a reminder of past days.

From the valve shafts to Treig Dam, the line has been converted to a road with only a length of rail ........

and a decaying sleeper remaining as evidence of the railway.

At Treig Dam, a short branch led down to a loading point at the end of the road up to Fersit and the trackbed can be made out as a heather clad shelf in the right foreground .......

...... and, a short distance further down, it becomes clearer at the point where the present day access track crosses the old trackbed.

Looking in the opposite direction, to the north, the trackbed can just be discerned leading down to the side of the road in the middle distance ......

....., where the branch ended at the roadside loading bank.

The Treig - Laggan railway continued northwards, at first barely discernible in the heather but, after crossing the river, it can be seen approaching Fersit.

Looking back towards Treig Dam from Fersit, the line is quite evident ........

..... but from Fersit, where it passes the site of the worker's camp, to the gravel pit further north, it now forms a roadway.

Fersit Camp was served by a halt on the West Highland Railway, sited in the sunlit area on the left hand side of the line.

At the gravel pit, the Treig - Laggan railway crossed the River Treig and the West Highland Railway on a long timber trestle. A few of the concrete pier bases remain to this day in the gravel alongside the river .....

..... and on the opposite side, another concrete foundation remains intact in the grass.

The concrete abutment where the viaduct crossed the West Highland Railway also remains largely intact.

The Treig - Laggan line connected to a workshops and sidings alongside the West Highland Railway, with a short branch leading back southwards, with the trackbed still visible ......

..... and the foundations of some buildings remain as moss-covered relics in the trees.

Back to the north, the trackbed is now a grassy path through the trees ......

Curving to left and right in a series of bends to gain height on the hillside.

Allt Chaorach Beag is now crossed by this bridge constructed from tram rails and old sleepers ......

..... and the trackbed continues ......

..... climbing through the trees .....

...... with further curves ......

...... before reaching the site of the branch to Adit A which dropped down to the left.

Near Adit A, a section of prefabricated track protrudes from the grass ......

...... alongside the waterlogged cutting that leads to the adit.

A few yard further on is the the site of the junction for the branch to Shaft C leading back northwards to the right.

Looking back, the line to Loch Treig drops down to the right and the Shaft C branch follows the present day forest road leftwards.

The branch crossed Allt Chaorach Mor ......

...... where some further lengths of rail can be found, both upstream .....

...... and downstream.

Intake B is a short distance upstream.

Emerging from the forest, the branch followed a horseshoe curve, leading back across Allt Choarach Beag on a route followed by the present access track.

A view from the far side of the curve, looking northwards.

Intake C lies at the end of the branch ......

...... with Shaft C immediately adjacent.

Back on the line toward Loch Laggan, the trackbed is again followed by the present day forest road, with fine views to the north ......

...... and looking back, to the south.

Corrour Forest is now entered, roughly midway between Loch Treig and Loch Laggan.

The fence on the right of the track marks the site of Adit B .....

...... in the cutting below .....

...... which was served by a branch that led back into the trees on the right.

Little remains of the branch, except for this almost hidden culvert over a small stream ......

...... but more visible from the other end.

Adit B at the end of its access cutting.

The Treig - Laggan line then affords further fine views back towards Loch Treig ......

....... and onward towards Loch Laggan.

Back at Treig Dam, the Upper Works Railway curves away from the road forming a pleasant walk through the birch trees ........

with more decaying sleepers visible in the muddy trackbed .......

before reaching Bridge No.2

Bridge No.2 on the Upper Works Railway was rebuilt in 1957 and crosses an un-named stream above Fersit.

Immediately beyond Bridge No.2, a section of rail, a sleeper buried in the grass and some scraps of metal mark the site of the speeder shed.

The line continues, curving round the hillside ........

and a pile of sleepers lies at the lineside above An Dubh Lochan.

More sleepers in this view looking across Glen Spean ........

before, with a final look over Tulloch to Creag Meaghaidh ........

the line turns into the valley of Allt Laire.

Bridge No.3 was replaced by a culvert and the grassy embankment shows in the foreground of this view back to Glen Spean.

Stob Ban, Sgurr Innse and Stob Coire na Ceannan form the backdrop ........

before the branch to Intake 1 comes in from the lower right.

A stub of rail protruding from the ground marks the site of the junction to Intake 1, with the UWR curving to the right and the branch dropping alongside the trees in this view down Allt Laire.

The sleepers remain in place on the Intake 1 branch looking up to the junction with the Upper Works Railway.

Bridge 4a crosses Allt Laire on the Intake 1 branch ........

and from the far side of the stream, the branch can be clearly seen climbing to the UWR crossing the hillside above.

In this view, the UWR can be seen curving round the hillside as it heads down down the valley towards Glen Spean whilst the branch to Intake 1 drops to cross Bridge 4a.

The trackbed of the Upper Works Railway then follows the bank of Allt Laire ........

before reaching this small bridge as the valley opens out.

Looking in the opposite direction, up the valley, the same small bridge lies in the foreground but the bridge over Allt Laire has gone.

Continuing up the valley, the trackbed heads towards Stob Coire Easain before curving to the right ........

in a 180 degree hairpin bend.

A final look up Allt Laire to Stob Choire Mheadhoin and Stob Coire Easain shows the trackbed in the foreground curving to the right before looping round the hairpin bend to cross the grassy embankment above the stream.

The next section of the trackbed has been converted to a road but a short section remains where it contours round the hillside.

When the road turns north to drop down to Intake 2, the trackbed continues onwards as a grassy track across the heather.

Slightly further on the course of the branch to Intake 2 can be seen in the distance sweeping back down the slope .........

and the course of the UWR continues in a series of curves ..........

towards the Intake 2 junction.

Immediately before the junction, the trackbed opens out at the site of the former passing loop, seen here looking back to Stob Coire Easain.

At Intake 2 junction, the branch can be clearly seen curving to the left in this view back along the UWR towards the passing loop.

The short branch to Intake 2 drops down the slope ..........

and curves around towards Allt nam Bruach.

Looking back up towards the UWR, the course of the Intake 2 branch is clearly visible ..........

before a short distance further, the branch ends alongside Allt nam Bruach.

Returning to the Upper Works Railway, the branch to Intake 2 comes in from the right and the trackbed continues west above Glen Spean.

Another look back along the trackbed shows the twists and turns to follow the contours .........

before reaching the culverted crossing of Allt Dubhaig at Bridge No.6

Just beyond Bridge No.6, sleepers remain in position on the trackbed ..........

and sleepers lie at the lineside.

Bridge No.7 crossing Coachan Daraich lies in the foreground of this view over Glen Spean to the hills above Glen Roy ...........

and in this view back over Glen Spean.

Another glance back to the west shows the mountains above Loch Treig.

A short embankment takes the line over another culvert ...........

followed by a shallow cutting with yet more sleepers cast aside in the grass ...........

and then lengths of rail in the muddy trackbed.

A pair of rails, three feet apart, remain on the trackbed above the Braes of Lochaber.

The line traverses the hillside in this view over the Monessie Gorge ..........

and continues westwards on a terrace on the hillside ..........

crossing a small stream on this bridge high above Monessie.

The trackbed can be clearly seen running along the hillside before climbing round the ridge in the distance.

The girders of another small bridge can be seen in this view looking back over Glen Spean to Creag Dhubh ..........

and a short distance further on, we reach the loco shed at Adit 3 above Monessie.

A long look back along Glen Spean shows the trackbed in the foreground and in the distance as the lower of two lines traversing the hillside, the higher being one of the sets of parallel roads that can be seen in Glen Spean and Glen Roy.

Bridge No.8 crosses the gully of Cruaidh Allt .........

and from the other side, the rails give the impression that the line is still in use.

A rock cutting then leads onto ..........

Bridge No.9, the highest bridge on the line.

Bridge No.9 is remarkably intact crossing this unnamed stream .........

and would provide a fine vantage point to photograph a train whilst looking back eastwards.

Bridge No 9 was rebuilt in 1939 and lies in a spectacular position above Roy Bridge.

A short distance westwards, Bridge No. 10 crosses one of the streams forming Allt Beinn Chlianaig .........

closely followed by Bridge No 11 over the other.

Bridges 11 and 10 can both be seen in this view back eastwards.

A short distance further on another glance back up Glen Spean shows the line making its way around the hillside and marks the junction of the incline to Intake 4.

Intake 4 on Allt Beinn Chlianaig lies some 150 feet above the line and was served by an incline built in 1966..

The incline up to Intake 4 can be seen in this view looking back down to the Upper Works Railway and Glen Spean .......

and further down some of the sleepers lie in the grass alongside.

The trackbed of the UWR continues westwards as the slopes of Aonach Mor start to dominate the view ahead.

A grassy embankment marks the approach to the culverted Bridge No.12 and the ballast pit by Allt an Easain and Bridge No.13.

The culvert at Bridge No.13 has collapsed revealing its cast iron plates.

At the ballast pit by Bridge No.13, the short siding can just be made out ........

and looking back to the east, the UWR can be seen making its way round the hillside with the new access track to Intake 4 crossing in the foreground.
