MILLIONS more people are working from home to try and avoid the severe disruption soaring temperatures are causing to transport networks across Scotland.
Road traffic and public transport usage dropped on Monday after people were urged to avoid unnecessary travel.
In Glasgow, there have been problems between Queen Street and Hyndland stations.
Chief spokesman for Network Rail Kevin Groves said journeys which typically take two hours could take “more than four hours” as emergency measures have been brought in to prevent trains derailing.
Network Rail also said that the number of passengers using major stations across Britain on Monday was around 20% down on a week ago.
Location technology firm TomTom said road congestion at 9am was lower in most UK cities than at the same time last week.
Glasgow specifically saw a drop from 17% to 12%.
The figures reflect the proportion of additional time required for journeys compared with free-flow conditions.
Jake Kelly, also from Network Rail, warned of travel disruption and told BBC Radio 4’s Today programme that the return of normal services on Wednesday “will depend on the damage that the weather does to the infrastructure”.
