In 2006, DRS started a new service, the "Tesco Express", on behalf of Eddie Stobart in partnership with Tesco, the UK's largest food retailer, to move containers from Daventry north to Mossend and Inverness using a new dedicated low-emission Class 66 locomotive in Eddie Stobart livery, 66411 "Eddie the Engine". A daily service from Grangemouth to Inverness followed in 2009, with another Class 66 in a promotional livery, this time 66414 "James the Engine". The Daventry – Scotland Stobart contract transferred to DB Schenker in January 2010, along with the onward daily service to Inverness, though this reverted to DRS operation in summer 2011.
