Michigan Line

Amtrak owns the 98-mile (158 km) section between Porter, Indiana, to Kalamazoo, Michigan, the longest stretch of Amtrak-owned rail outside of the Northeastern U.S.

The entire corridor (including the portion owned by MDOT) is dispatched and maintained by Amtrak, which as of September 2021[update], is working to replace worn tracks and integrate the train signaling and communication systems.

Combined with a $196 million federal government grant announced the previous month to improve signaling and track quality, trains will be able to run at 110 mph (177 km/h) on 77% of the length of the Detroit–Chicago corridor.

[11] In October 2024, Amtrak was awarded an $8.4 million federal grant for design work to restore double track between Niles and Wayne Township.

The incident was investigated by the National Transportation Safety Board and was found to be an Amtrak contractor's fault, caused by one of its employees improperly applying jumper wires to the signal system, bypassing safeguards that had been designed to prevent such an occurrence.
