Track Geometry Measurement System (TGMS) Inspections; Extension of Comment Period

Notice of proposed rulemaking (NPRM); extension of comment period.

On October 24, 2024, FRA published an NPRM proposing to revise its regulations governing the minimum safety requirements for railroad track. The proposed changes would require all Class I and II railroads, as well as intercity passenger railroads and commuter railroads, to operate a qualifying Track Geometry Measurement System (TGMS), a type of automated track inspection (ATI) technology, at specified frequencies on all Class 1 through 5 mainline and controlled siding track that transports: annual tonnage greater than 10 million gross tons (MGT), regularly scheduled passenger rail service, or trains containing hazardous materials. FRA also proposed increasing the required frequency of TGMS inspections on Class 6 track. By this notification, FRA is extending the NPRM's comment period, which will close on December 23, 2024, by 15 days.
