A rock slide temporarily halted BNSF and Canadian Pacific Railway trains near Warner Road in St. Paul early Friday morning.

Rocks became loose around 1 a.m. near Mounds Park and fell onto the BNSF tracks and their service road near Warner and Childs Road, according to city officials.

No public roads were impacted, said Clare Cloyd, a spokeswoman for St. Paul Parks and Rec.

BNSF and CP Railway asked for traffic to be held while they cleared the area.
