 In December 2018, plans were introduced to revert the route to a bus-based operation after February 2019.The replacement road-based shuttle service would use four-to-six buses running on propane fuel or compressed natural gas, whilst the People Mover tracks would remain in place for the pneumatic tube system.In 1997, the three hospital operations were combined under Indiana law creating a shared staff of over 10,000 employees who could be required to travel between the campuses.
