Study says HSR tunnels could hold lessons for California system

High-speed rail construction projects have frequently required long tunnels to reduce travel time and distance.

FRA wants states to verify proper function of traffic lights tied to crossings

The Federal Railroad Administration (FRA) has called on state departments of transportation to verify that railroad crossing warning systems interconnected to traffic lights function properly and urged states to add event recorders to traffic lights connected to railroad crossing systems so information obtained during inspections can be used to improve safety. Across the United States, there are nearly 5,000 railroad crossings interconnected with traffic lights.
