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. 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:
