Falling debris outside the Hoosac Tunnel interrupted freight rail service this weekend for the second time in 10 months.

The Berkshire Eagle.com reports Pan Am Railways posted on a social media account that a routine track inspection around 8:45 a.m. Saturday discovered a landslide outside the west portal in North Adams. Based on an Eagle photograph, the landslide occurred about 200 feet from the entrance.  There appears to be no damage to the tunnel.

The Billerica-based transportation company had sent an engineering team and repair crew to clear the eight inches of mud and stone over the rail head.

The Norfolk Southern Railways partners with Pan Am on the use of the tunnel.
