Smart Rocks, Smart Tamper: Investigating the Mechanics of Ballast Tamping

ATLANTA – Railway Track & Structures, April 2024 Issue: There are many forces that work to deteriorate track geometry over time. These forces don’t begin and end at the wheel/rail interface; they are transmitted to the vehicles and their components and into the track structure and its components. On ballasted track, ballast absorbs these forces, and its maintenance is critical to preserving and correcting several types of track geometry defects.

Bridge Collapse Shuts Down Port of Baltimore — From Our Colleagues at Railway Age

BALTIMORE – The tragic early morning collapse of the I-695 Francis Scott Key Bridge, which spans the Patapsco River, following a bridge strike by a container ship weighing 95,000 gross tons, has brought the Port of Baltimore, an important trade hub, to a halt. The Port of Baltimore has suspended all vessel traffic into and out of the port until further notice. The accident is a serious blow to the port operations of both CSX and Norfolk Southern, particularly for intermodal container, automotive and coal traffic.
