Scotrail had announced on Tuesday afternoon that a power cable had fallen onto the line near Connel Ferry.
This had been preventing trains from serving any stations on the Oban-Crianlarich section of the West Highland Line since 1.30 pm.
The 4.11 pm Oban-Dalmally and 5.05 pm Dalmally-Oban services were cancelled, but the 4.34 pm Glasgow Queen Street-Oban and 6.11 pm Oban-Crianlarich services are now expected to run as scheduled.
