ScotRail says passengers need to take responsibility for their own hygiene - as it prepares to add more services to its timetables.
The operator says that physical distancing may not always be possible on its trains, and that people need to follow its five rules for safe travel.
These are:
- Do not travel if you feel unwell or have a temperature
- Travel away from the main commuting times (7-9am and 4-6.30pm) wherever possible, as trains will be busiest around then
- If you think it’s not safe to board a train, don’t do it and wait for another service
- Wear a face mask or covering and, where possible, maintain physical distancing
- Be patient - you might not be able to board your first choice of train, as physical distancing means most seats need to be left empty
From Monday, 60% of normal trains will be running - with several services running extra seats in an attempt to ensure people can stay distanced as much as possible.
There will also be hand sanitiser units at the busiest stations, while floor markings and signs are showing people how to stay two metres away from others.
David Simpson, ScotRail operations director, said: "Since the start of this pandemic, our staff across Scotland’s Railway have done a fantastic job. We are incredibly proud of their efforts to help customers travel safely.
"Providing hand sanitiser is the latest measure to keep people safe, but our message to customers remains the same: people should only travel if it is essential.
"For those who do travel, Scotland’s Railway cannot guarantee physical distancing at all stages of a journey because we only have a limited amount of capacity. That’s why following our five rules for travel is vital, particularly on face coverings. We need everyone to take personal responsibility for their travel choices.
"There have been changes to our daily routine in everything we do, and the railway is no different."
