The tunnel consisted of a single bore, 244 metres long, containing two running lines.

. The first of these was in 1949, when a serious fire destroyed two carriages of a south-bound express from Edinburgh. Seven passengers were injured, but there were no fatalities.

The second incident occurred on 17 March 1979 when, during improvement works, a length of the tunnel collapsed. Two workmen were killed, although 13 others managed to escape. Later it was determined that the ground was not stable enough to excavate and rebuild the tunnel, so it was sealed-up and a new alignment was made for the railway, in a cutting to the west of the hill.

The tunnel was also affected by the August 1948 floods. The damage caused by these floods led to the abandonment of much of the railway network in the south east of Scotland.

On 12 August 1948, some 6.25 inches (160 mm) of rain fell in the area; the total for the week being 10.5 inches (265 mm). Rain falling on the Lammermuir Hills

. The train was stopped somewhere near the tunnel, within one and a quarter minutes of the fire starting, but the fire spread rapidly and with such extreme ferocity that, within seconds, the brake-composite carriage was engulfed and the fire had spread to the coach in front. Most passengers escaped by running to the guard's compartment or forwards along the corridor, but some were compelled to break the windows and jump down onto the track. One lady was seriously injured by doing this.

The train crew reacted quickly to the incident. The four coaches behind the two ablaze were uncoupled and pushed back, leaving them isolated up the line. Having drawn forward and uncoupled the two burning vehicles, the driver proceeded with the front eight coaches to Grantshouse station.

The cause of the fire was thought to be a cigarette end or lighted match

Despite the severity of the blaze, which reduced the two carriages to their underframes, only seven passengers were injured, with no fatalities.

Tunnel collapse (1979)

The next significant event to occur at the tunnel was also the last, as it led to its abandonment.

Upgrading work

Work was being carried out to increase the internal dimension of the tunnel to allow 8 in 6 in (2.59 m) high containers to travel through it on freightliner

, digging out the floor of the tunnel and then laying new track set on a concrete base.

As the tunnel was on a very busy main line, and in order to minimise the disruption to passenger and freight services, it was decided that each of the two tracks through the tunnel would be renewed separately, with trains continuing to run on the adjacent open track.

Work was completed on the "Up" (southbound) track by 10 March 1979, and trains were then transferred to this track by the following day, to allow the "Down" (northbound) track to be modified.

Tunnel collapse

At the time the tunnel collapsed there were a total of 15 people and 5 items of plant inside. According to the Railway Inspectorate report, shortly before 3:45am the duty Railway Works Inspector noticed some small pieces of rock flaking away from the tunnel wall, approximately 90 metres from the southern portal

. He decided that it would be wise to shore up the affected piece of the tunnel and was making his way towards the site office to make the appropriate arrangements when he heard the sound of the tunnel collapsing behind him.

It is estimated that approximately 20 metres of the tunnel arch collapsed, with the resultant rock fall filling 30 metres of the tunnel from floor to roof, totally enveloping a dumper truck and a JCB

. Thirteen of the people inside the tunnel at the time of the collapse escaped successfully, but the dumper truck and JCB operators could not be accounted for, and were determined to have been killed in the accident.

 report was written by Lieutenant Colonel I.K.A. McNaughton, on 2 August 1983. The report concluded that it was impossible to be certain as to the cause of the collapse as access could not be gained to the collapsed portion of the tunnel.

The report did however suggest that the collapse was likely to be the result of over-stressing of the natural rock on which the brick arch rings were founded. It was likely to have happened at some time in any event and there was insufficient evidence to say whether or not it had been triggered by the excavation.

Finally the report stated that there were no grounds for finding any individual responsible for the accident. British Rail was however charged in the High Court

 to re-open the tunnel by removing the collapsed material and repairing the structure of the tunnel. However once the extent of the collapse became apparent, it was decided that this operation would be too difficult and dangerous, and that a more expedient and cost effective option would be to construct a new alignment for the railway.

This decision resulted in around one kilometre (1,100 yards) of existing railway (including the tunnel itself) being abandoned and replaced by a new section of line constructed in open cut, somewhat to the west of the original course. The operation to reopen the railway took five months of round-the-clock working. The portals of the collapsed tunnel were sealed to prevent unauthorised access.

Road diversion

As a result of the work to re-align the railway line, it was also necessary to alter the course of the A1 trunk road. A map of the area, clearly showing both the railway and the road diverting to the west is available here.

Visible remains

Since the tunnel was closed, the landscape has gradually 'returned to nature'. The southern portal has been covered by the hillside, and the only clues to the route of the old line are a dry-stone wall marking the railway boundary, and a disused bridge that used to carry the A1 main road over the line.
