On June 25, 2018, service patterns were changed to eliminate all left-track running. This change meant passengers arriving westbound at Lougheed on the Expo Line who wished to continue towards VCC–Clark could either change platforms at Lougheed or remain on their Expo Line train until its terminus at the next station, Production Way–University, where they could make a same-platform transfer to a westbound Millennium Line train. For passengers arriving eastbound at Lougheed, transfers between eastbound Millennium and Expo Line trains were now same-platform. TransLink stated the change to traditional right-track running would provide faster and more reliable trips for passengers as the many track changes the initial service pattern required had resulted in delays.
