MDOT is proposing to leave roughly 160 miles of single track between Porter, IN and Ypsilanti, MI. This means a loss of flexibility in scheduling, potential for cascading delays, and a loss of potential growth.
Advanced dispatching and signaling help mitigate, but do not eliminate, these limits. The estimated cost to add double track is $320 million and the EIS represents a 20-year plan that can be done in independent phases.
Why not include the ability to grow?
A Wolverine Corridor that is double tracked would allow for flexibility, frequent service, and reliability that is not possible to achieve with a single track.
