The fault caused a wave of disruption across Scotland’s rail network.
Commuters travelling between Inverness and the Central Belt faced delays of up to 60 minutes as trains ran at a reduced speed along the route.
In a statement, posted on their website during the disruption, a ScotRail spokesman said: “We have received reports of a signal fault between Blair Atholl and Dalwhinnie. Because of this fault our services have to run through this area at a slower speed than normal.
“Staff are on site have found multiple blown fuses which they are in the process of replacing but the area affected is quite large so may take some time to complete.”
