CPKC derailment in Wisconsin causes service disruptions

A CPKC train derailed near Lowell, Wisconsin, on Friday afternoon, disrupting Amtrak routes, raising environmental concerns, and forcing freight and passenger operators to adapt quickly with emergency responses and alternative transport solutions. This is reported by the railway transport news portal Railway Supply.

CPKC quickly deployed hazardous materials experts, environmental crews, and senior officials. The company reported that at least one car leaked oil, and it pledged to continue clean-up operations throughout the night with additional equipment.

Passenger service disruptions caused by CPKC derailment

The derailment forced Amtrak to reroute the Empire Builder and Borealis trains. Eastbound services combined at La Crosse and continued to Chicago via BNSF tracks. Westbound Empire Builder passengers also faced detours, and buses covered missed stops.

So, while no injuries occurred, the ripple effect extended beyond freight operations. Amtrak worked to reduce delays, but passengers faced schedule changes and replacement buses for critical segments between La Crosse and Chicago.

Environmental and regional impact

Residents expressed concern about the environmental risk of leaked crude oil. Specialists prepared to test soil and water conditions, because early assessments suggested product spillage. Local and regional planners also coordinated to minimize freight congestion during the cleanup.

This incident highlighted the vulnerability of busy freight corridors and the importance of coordinated crisis management. And while rail officials stressed safety and transparency, communities continued to monitor potential long-term effects.
