Abstract
FRA is 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 proposes increasing the required frequency of TGMS inspections on Class 6 track.
