BRUNSWICK, Maine (AP) — Neighbors of a proposed Amtrak train depot in Brunswick have filed a lawsuit to block the station from being built.

In a complaint in Cumberland County Superior Court, a group of 14 neighbors is asking a judge to overturn a zoning variance allowing a 40,000-square-foot depot in a zone with a 20,000-square-foot maximum.

The group says a train layover and maintenance facility would increase noise, hurt air quality and reduce the market value of their homes.

Northern New England Passenger Rail Authority Executive Director Patricia Quinn tells The Times Record her agency intends to work with neighbors and has hired a firm to determine the impacts of the facility.

Amtrak’s Downeaster track extension from Portland to Brunswick is expected to be completed by the fall of 2012.
