Newmarket Holidays "is up and running again" after celebrating its first departure since suspending operations in March.
Eleven guests embarked on the operator’s first Scottish Highlands Railways trip since lockdown, which departed on 21 August.
They were accompanied by a tour guide and Newmarket product director Andy Jones.
All of Newmarket’s September and October departures will be accompanied by a tour guide and member of the operator’s product and operations to monitor adherence with new Covid protocols and direct contact with clients during the tour.
The company has since operated a weekend Belfast tour, and is now working on restoring "an extensive UK and Ireland programme".
