A coalition that supports passenger rail service will hold a public forum Thursday in Portland on a proposed train service linking Portland, Lewiston and Montreal.

The event will feature a presentation on the state of passenger rail and next steps for the proposal. The forum will be held at Stroudwater Distillery at Thompson’s Point at 6 p.m.

A passenger rail link between the three cities has been considered for years. Last year, the Legislature and cities of Lewiston and Auburn provided funding to draw up a service development plan, said Tony Donovan of the Maine Rail Transit Coalition.

The plan would include possible route maps, stop locations and equipment, Donovan said.

Speakers at the forum will include Donovan, representatives from AARP and the Sierra Club, Dr. Monika Bissell from the Maine College of Health Professionals and Montreal train advocate Francois Rebello. The event will be introduced by Portland City Manager Jon Jennings.

The event is free and open to the public.
