SF 40: Requiring the installation and maintenance of train defect detectors on railway branch lines, and providing penalties

Died when the session ended · The General Assembly adjourned on October 2, 2026. Bills that didn’t pass both chambers died.

What it does

trains operate. If the branch line is longer than miles, one defect detector is required at least every miles. Railroad companies that operate trains on the same railway may share such costs and are jointly and severally liable in any suit arising from the installation and maintenance of all defect detectors, or lack thereof, on or along the railway branch line.5 for every mile of the branch line, or every mile that is more than miles away from a defect detector, as applicable. A railroad company is also subject to a schedule “five” penalty for each time a train crosses or passes by a defect detector that fails to notify the train crew of a detected defect.
