Train P512, which had left Union Station in Worcester at about 7:30 a.m., struck the trespasser five minutes into its journey near the 800 block of Franklin Street, said MBTA spokesman Joe Pesaturo.

The accident caused inbound commuter rail delays as police investigated at the scene, Pesaturo said.

All stops between Southborough and South Station were affected by the delays. Passengers on the affected train were transported after an hour’s wait to another train for the remainder of their commute.

Shuttle bus service has been set up between Worcester and Grafton, carrying passengers around the accident scene, Transit Police said.
