An overnight landslide near the city's West End shut down rail traffic and dropped debris into a business along West Carson Street.
The landslide, one of many in the region that likely were the result of the remnants of Hurricane Sandy earlier this week, occurred sometime around 2 a.m. Rocks and dirt fell across the railroad tracks in the area.
Officials were working before dawn to clear the busy rail line and to remove a large boulder and other debris that struck Jackson Welding. The first train was able to pass the site by 7:24 a.m.
West Carson Street is not affected by the slide.
In northeastern Allegheny County, a landslide that occured Thursday still has a road closed this morning.
Pleasantville Road at Burtner Road in Harrison will be closed to traffic until further notice while debris is removed and the hillside is safe from additional slides onto the road.
