Me. Rev. Stat. tit. 23, § 5125

No person is entitled to transportation over a steam railroad or upon any ferry or in a taxicab or public automobile, who does not on demand first pay the established fare. Whoever, while being transported over any steam railroad, ferry or in a taxicab or public automobile, willfully refuses on demand to pay the established fare and whoever fraudulently evades payment of the established fare by giving a false answer, by traveling beyond the place to which the person has paid or by leaving a train, ferry, taxicab or public automobile without paying the established fare, whether that fare is demanded or not, forfeits not less than $5 nor more than $20, to be recovered on complaint. No person, without right, may loiter or remain or place or cause to be placed any property or obstruction on the right-of-way of a railroad corporation or on land owned by a railroad corporation adjoining or adjacent to its right-of-way or, without right, may board or attempt to board or remain on any railroad freight train, freight car, caboose, locomotive or work equipment. Any person violating this portion of this section is guilty of a Class E crime.
