Service Overview
Service Definition
The Wolverine is a higher-speed passenger train service operated by Amtrak as part of its Michigan Services. It provides three daily round-trips connecting Chicago, Illinois, with Pontiac, Michigan, traversing a significant portion of the Midwest.
Route and Distance
The service covers a distance of 304 miles (489 km), operating between Chicago Union Station and Pontiac Transportation Center. Key intermediate cities include Ann Arbor and Detroit, making it a crucial link for these major metropolitan areas.
Operational Metrics
The average journey time for the Wolverine is approximately 6 hours. The service frequency consists of three daily round-trips, ensuring consistent connectivity throughout the day. Train numbers for this service are 350, 352, 354 (eastbound) and 351, 353, 355 (westbound).
Ridership
In Fiscal Year 2023, the Wolverine demonstrated robust ridership, carrying 420,569 passengers. This represented a notable increase of 14.5% compared to the previous fiscal year, indicating growing demand for this service.
Historical Context
Origins and Amtrak Transition
Prior to Amtrak's formation in 1971, the route was served by trains like the Wolverine under Penn Central. Amtrak retained two services, truncating the route to Detroit and making minimal initial changes. The service inherited train numbers that are still in use today.
The Turboliner Era
In April 1975, Amtrak introduced French-built Turboliner equipment, which led to significant ridership increases. These trains, though fast, were limited by track quality. By March 1976, Amtrak began supplementing them with conventional equipment like Amfleet coaches, and individual train names were reintroduced.
Service Evolution and Modernization
Amtrak extended the Wolverine and Twilight Limited to Pontiac, Michigan, in May 1994, introducing new stations and a new Detroit station location. Individual train names were again consolidated under the Wolverine branding in 2004. More recently, the service has seen upgrades with Siemens Charger locomotives and Siemens Venture passenger cars, enhancing both performance and passenger amenities.
Route and Infrastructure
Track Ownership and Segments
The Wolverine operates over a complex network of tracks owned by various entities. Key segments include Amtrak-owned trackage between Porter, Indiana, and Kalamazoo, Michigan (the longest Amtrak-owned segment outside the Northeast Corridor), and trackage owned by Norfolk Southern, Canadian National, and MDOT.
Higher-Speed Operation
The corridor is recognized as a high-speed rail corridor by the Federal Railroad Administration. Significant investments have been made to upgrade track speeds, with sections now allowing operation up to 110 mph (177 km/h). These upgrades involve track replacement, curve modifications, and grade crossing improvements.
Key Stations and Connections
Major Stops
The Wolverine serves 17 stations along its route. Notable stops include Chicago Union Station, Kalamazoo Transportation Center, Ann Arbor Station, Detroit Station, and the terminal in Pontiac, Michigan.
Intermodal Connections
The Wolverine provides critical connections to various local and intercity transit systems. At major hubs like Chicago Union Station, passengers can access Amtrak's long-distance and other intercity services, Metra commuter rail, and the Chicago 'L' system. Stations in Michigan offer connections to local bus services (like TheRide in Ann Arbor, DDOT and SMART in Detroit) and intercity bus providers such as Greyhound.
Rolling Stock
Locomotives
The Wolverine is primarily powered by state-owned Siemens Charger locomotives. These modern diesel-electric locomotives are equipped with Positive Train Control (PTC) systems, a requirement for operating above 79 mph, making them essential for the higher-speed segments of the route. They operate in a push-pull configuration.
Passenger Cars
The fleet consists of Siemens Venture passenger cars, including business class cars and cafe cars. Historically, Amfleet and Horizon cars were used, and some may still be in service during the transition period. The Venture cars represent a significant upgrade in passenger amenities and comfort.
Future Developments
International Expansion
Amtrak has proposed extending service from Detroit to Toronto, Canada, via the WindsorโQuebec City Corridor. This ambitious plan requires significant track upgrades and the establishment of border processing facilities, with service tentatively planned to commence in 2027, pending approvals.
Infrastructure Enhancements
Long-range plans include increasing the frequency of round trips and expanding double-tracking along the route to improve reliability and speed. These infrastructure investments are crucial for supporting higher operational speeds and increased service levels, aligning with broader goals for passenger rail development in the region.
