A landslip has closed the Oban branch of the West Highland Railway Line and a major road in Argyll.
Network Rail said on Monday afternoon that engineers had been sent out to the site near Falls of Cruachan to investigate and later confirmed the landslip.
ScotRail announced to customers that the line was shut between Dalmally and Falls of Cruachan due to suspected flooding and warned of disruption to services.
The rail provider added that services between Glasgow Queen Street and Oban could be cancelled, delayed or revised and services between Glasgow Queen Street and Mallaig were subject to delay or revision.
Traffic Scotland said that due to the landslip, the A85 is also closed at Bridge of Awe, Lochawe, due to a risk of falling rocks.
An 84-mile diversion has been put in place and drivers have been urged to plan ahead.
A Police Scotland spokesperson said: “A full road closure is in place on the A85 at Lochawe due to a landslide. It will remain closed until at least Tuesday morning, pending a further inspection of the site. A diversion is in place.”
