Maine Department of Transportation

The Maine Department of Transportation, also known as MaineDOT, is the office of state government charged with the regulation and maintenance of roads and other public infrastructure in the state of Maine. An exception is the Maine Turnpike, which is maintained by the Maine Turnpike Authority. MaineDOT reports on the adequacy of roads, highways, and bridges in Maine. It also monitors environmental factors that affect the motor public such as stormwater, ice/snow buildup on roads, and crashes with moose.

MaineDOT owns hundreds of miles of railway track in the state, much of it acquired as the result of abandonment of rail on unprofitable lines by private carriers. The state does not itself operate a railway, instead leasing lines or engaging private contractors to operate on state-owned rails:

In 2012, MaineDOT sought an operator to restore passenger service on St. Lawrence and Atlantic Railroad tracks to Lewiston and Auburn, Maine."[4]
