OH SB250

Establishes separate wayside detector system spacing requirements based on railroad carrier class: Class I carriers must install systems not more than 10 miles apart, Class II carriers 25 miles apart, and Class III carriers 35 miles apart.

Requires the Public Utilities Commission and Department of Transportation to work with railroad companies to ensure wayside detector systems are properly installed, maintained, and operational in compliance with federal standards and industry best practices.

Mandates that persons receiving defect alerts from wayside detector systems immediately notify train operators if the message was not automatically transmitted to them.

Allows Class II and III carriers to deviate from spacing requirements if natural terrain or other reasons prevent compliance, subject to written explanation submitted to the Public Utilities Commission; exempts tracks with speed limits of 10 mph or less from these requirements.

Requires the Public Utilities Commission to review Ohio train derailments caused by bearing or axle failure and report findings to state leadership by December 31, 2028.
