The Montreal, Maine and Atlantic Railway (reporting mark MMA) was a Class II freight railroad that operated in the U.S. states of Maine and Vermont and the Canadian province of Quebec between 2002 and 2014. It was headquartered in Hermon, Maine.
Its Canadian subsidiary was named the Montreal, Maine and Atlantic Canada Company with offices in Farnham, Quebec. With the exception of an independently owned low-speed tourist train (the Orford Express) on one small segment between Magog and Sherbrooke, there was no passenger service on the MMA system.
MMA and its Canadian subsidiary entered Chapter 11/CCAA bankruptcy protection in August 2013 as a direct result of the Lac-Mégantic derailment, a runaway train incident in July 2013 which resulted in an estimated $200 million in damage and the deaths of 47 people.
MMA's assets were sold at auction to Railroad Acquisition Holdings, LLC, a subsidiary of Fortress Investment Group, LLC on January 21, 2014. Fifteen locomotives worth $1.6 million were excluded from the deal and will be sold separately. The sale was approved by bankruptcy judges on January 23, with the transfer of assets expected to occur on or before March 31, 2014. Railroad Acquisition Holdings, LLC has established a new railroad named Central Maine and Quebec Railway (reporting mark CMQ) to operate the former MMA rail lines.
