The U.S. operations of the Class I railroads are nearly fully interoperable, with 91.6% of the network reaching interoperability by the end of the third quarter, according to data from the Federal Railroad Administration (FRA).
At the end of the second quarter, U.S. Class I rail operations were 79% interoperable.
Interoperability is the final step toward becoming fully compliant with the federal positive train control (PTC) mandate. By Dec. 31, the U.S. operations of the Class I railroads, Amtrak and selected commuter and regional railroad lines must have PTC fully implemented and running on their networks.
