Network Rail has said that the rail line between Fort William and Mallaig will reopen this morning following a week of emergency repairs.
The line was closed on 22 January after 1,000t of material from a slope failure engulfed the rail line and derailed the front bogie of a two carriage train.
Work last week focused on clearing the track so that specialist equipment could be brought in to remove the affected train.
Engineers have worked over the weekend to install additional drainage and carry out track repairs, as well as undertake work to secure the slope above the railway.
“The isolated location, and steepness of the slope above, has made this a complex recovery operation,” said Scot Rail Alliance infrastructure director David Dickson.
