As part of an Amtrak project to replace railroad ties across its New England Division, there will be service interruptions every Friday between July 12 and Aug. 9 on the Providence, T.F. Green and Wickford Junction stations. The service interruptions will require temporary adjustments to the schedules of six trains that service Rhode Island’s commuter rail stops.
