From tomorrow (Tuesday, 11 March), ScotRail will operate seven-carriage trains between Glasgow and Crianlarich, and five-carriage trains between Crianlarich and Fort William.
The improvements have been made possible due to the completion of platform extension works by Network Rail, which now allow the train operator to make better use of its Highland Explorer carriages. The use of active travel carriages had previously been restricted on services due to platform length limitations.
The Highland Explorer carriages will be used on the following services:
ScotRail will also begin its summer service strengthening tomorrow, earlier than in previous years. Traditionally starting from the last weekend in March, this year summer strengthening will start on 11 March to accommodate increased demand.
- 12:22 Glasgow to Fort William.
