Ann Arbor Railroad Company case Ann Arbor Railroad (AAR) is a railroad company that is partly financed by the US Department of Transportation through its high-speed rail stimulus initiative. AAR operates daily train service between Detroit, MI and Chicago, IL. The Company operates two classes of passenger trains: slow-speed and high-speed. AAR built and currently maintains a roadbed and tracks between the two cities as well as stations in both Detroit, MI and Chicago, IL.. The tracks and signaling equipment cost approximately $1 million per mile to build and will be depreciated over thirty years. The bulk of the Company's station-related costs arise from the Detroit and Chicago stations. Costs for the intermediate stations, which are only used by the slow-speed trains, are largely paid for by the local municipalities. AAR does not own any trains, but leases them. Specifically, it leases 10 high-speed trains (locomotives plus carriages) from Siemens AG and 10 slow-speed trains (locomotives plus carriages) from GE. Locomotives refer to the motorized entity pulling the carriages. Carriages carry passengers but are unable to move autonomously. The Company is responsible for maintaining the trains. The high-speed trains are technologically advanced and more costly than the slow-speed trains, which are technologically simpler and older. AAR employs the train engineers and the onboard service staff. The Company has contracted with Gourmet Services to provide complimentary food and drinks to high-speed passengers. The contract entails a fixed monthly payment of $700,000 plus $8 per passenger. Slow-speed train passengers receive no complimentary items; they can buy food and beverages from an independent catering company with no profit or loss for AAR.
