MONTPELIER, Vt. – A plan to use a dormant railroad line to run a cargo train through Vermont’s small state capital is raising concerns among school officials and some businesses.

The 10-car trains will pass through the city at least twice a day, ferrying waste granite from Barre Town to Montpelier Junction. The material is destined for a dike system in Florida.

Empty cars started running this week. The full cars are expected to start next week, sooner than originally planned.

Montpelier High School says it’s scrambling to get the word out to school kids, who often take shortcuts on the railroad tracks and two trestles.

The school will hold a schoolwide assembly next week to discuss the issue.
