SF 337: Requiring the installation and maintenance of train defect detectors on railways, and providing penalties

Became SF 512 · Its progress continues under the new number.

What it does

This bill requires a railroad company to install and maintain at least one defect detector, as defined in the bill, every miles on or along the railways upon which the company’s trains operate. 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. A railroad company that operates a train on a railway that does not have a defect detector installed every miles is subject to a schedule “one” penalty under Code section 327C.5 for every mile of the railway that is more than miles away from a defect detector. A schedule “one” penalty is a fine of $100 per violation.
