It’s “all aboard” for officers from at least 10 Maine police agencies as they take the train to learn more about the laws against trespassing on railroad property. The police will board a Maine Eastern Railroad train on Friday in Wiscasset and travel to Brunswick, where they’ll continue their discussion at Town Council chambers. Leading the discussion will be Michail Grizkewitsch, a trespass specialist for the Federal Railroad Administration. Trespassing includes walking, hunting, riding a snowmobile, ATV, or motorbike, or cross-country skiing on or along a railroad right of way. It also includes fishing or jumping from railroad bridges, and vandalizing or tampering with rail equipment. The safety of officers investigating such incidents will also be covered on Friday’s train ride.
