Overview
Central Maine & Quebec Railway, commonly identified by the reporting mark CMQ, was a privately owned Class II freight railroad that operated a cross-border network in the northeastern United States and southeastern Canada. Its principal system connected communities and industrial customers in Maine and Quebec, with an additional route reaching Newport, Vermont. The company was headquartered in Bangor, Maine, while its U.S. corporate entity maintained offices in New York and its Canadian entity maintained offices in Sherbrooke, Quebec. CMQ was created during the restructuring of the Montreal, Maine and Atlantic Railway after that railroad entered bankruptcy protection in August 2013. The Montreal, Maine and Atlantic had been heavily affected by the Lac-Mégantic rail disaster, in which a runaway crude-oil train derailed in Lac-Mégantic, Quebec, on July 6, 2013. The disaster killed 47 people and caused extensive destruction in the town center. The resulting bankruptcy proceedings in the United States and Canada enabled the sale of the railroad’s operating assets. In December 2013, Railroad Acquisition Holdings, an affiliate of Fortress Investment Group, submitted a stalking-horse bid for the operating rail lines. The bankruptcy trustee accepted the bid in January 2014, and Fortress announced the formation of Central Maine & Quebec Railway as the new operating company in February. The transaction was completed in March 2014, although CMQ received its Canadian certificate of fitness from the Canadian Transportation Agency on June 24, 2014. The company’s U.S. and Canadian entities were registered in February 2014. At the beginning of its operation, CMQ inherited a rail system that required substantial rehabilitation. John E. Giles of Railroad Acquisition Holdings inspected the full route in March 2014 and estimated that between $10 million and $20 million would be required over three years to repair track and related infrastructure. The condition of the network was also a limiting factor in the company’s ability to handle crude oil and other dangerous goods. CMQ acquired ten GMD SD40-2F locomotives from Canadian Pacific Railway in 2014 and used them as part of its freight operation. The company’s core network covered approximately 481 route miles, including lines in Maine, Quebec, and Vermont. Its principal routes included the Searsport, Millinocket, Brownville, Moosehead, Sherbrooke, Adirondack, Newport, Stanbridge, and St-Guillaume subdivisions. The network served forest-products, manufacturing, energy, agricultural, bulk-material, and other industrial customers, and connected with larger railroads including Canadian National, Canadian Pacific, CSX Transportation, and regional railways in Maine, Vermont, and Quebec. CMQ also expanded beyond its inherited core system. In 2015, the Maine Department of Transportation selected the company to operate the state-owned Rockland Branch between Brunswick and Rockland. CMQ began operating the line on January 1, 2016, replacing Maine Eastern Railroad. The change ended the passenger excursion service that Maine Eastern had operated, because CMQ’s proposal focused on freight operations. In 2017, CMQ began operating the former Norfolk Southern Hannibal Subdivision in Ohio for Fortress-related industrial interests, although that operation was separate from the main Maine-Quebec network. CMQ considered restarting crude-oil transportation in January 2016, but the plan did not proceed, in part because of petroleum-market conditions. The company continued to operate freight services until Canadian Pacific announced an agreement to acquire it on November 20, 2019. Canadian Pacific described the transaction as a way to regain former Canadian Pacific routes, establish a more integrated coast-to-coast Canadian network, and strengthen its presence in New England. The acquisition closed on June 4, 2020, ending CMQ as an independent railway brand. Some operations associated with Fortress interests, including the Ohio industrial operation, continued under other arrangements after the acquisition.
History
Central Maine & Quebec Railway emerged from the bankruptcy restructuring of Montreal, Maine and Atlantic Railway. That predecessor had itself developed from assets associated with Iron Road Railways, but its later history was dominated by the July 2013 Lac-Mégantic rail disaster. A runaway crude-oil train derailed in Lac-Mégantic, Quebec, killing 47 people and destroying much of the downtown area. Montreal, Maine and Atlantic subsequently sought protection under Chapter 11 in the United States and under Canada’s Companies’ Creditors Arrangement Act on August 7, 2013. The proceedings created a framework for selling the operating railway and related assets. Railroad Acquisition Holdings, LLC, an affiliate of Fortress Investment Group, submitted a stalking-horse bid in December 2013. The bankruptcy trustee accepted the bid in January 2014. Fortress then established Central Maine & Quebec Railway as the new operating entity. The U.S. company was named Central Maine and Québec Railway US Incorporated and maintained offices in New York, while the Canadian company was named Central Maine and Québec Railway Canada Incorporated and maintained offices in Sherbrooke. Both entities were registered on February 14, 2014. The transaction closed in March, and the Canadian Transportation Agency issued CMQ a certificate of fitness on June 24, 2014. The new operator inherited a large but distressed regional network. During a March 2014 inspection, John E. Giles of Railroad Acquisition Holdings traveled across the line and assessed its track, facilities, and industrial connections. He estimated that $10 million to $20 million in investment would be needed over three years to restore the railway. The condition of the line affected the company’s ability to move crude oil and other dangerous commodities. CMQ acquired ten GMD SD40-2F locomotives from Canadian Pacific Railway in 2014 as it built its operating fleet. CMQ’s principal system extended from Maine through Quebec, with a smaller Vermont component. In Maine, its routes included the Searsport, Millinocket, East Millinocket, Madawaska, K.I., and portions of the Moosehead subdivisions. In Quebec, the network included the Sherbrooke, Adirondack, Stanbridge, and St-Guillaume subdivisions. The Newport Subdivision reached Vermont. In total, the company reported approximately 481 route miles: about 221 miles in Maine, 237 miles in Quebec, and 23 miles in Vermont. Interchange relationships connected CMQ with Canadian National, Canadian Pacific, CSX Transportation, Eastern Maine Railway, Maine Northern Railway, St. Lawrence and Atlantic Railroad, and Washington County Railroad. The railway’s business centered on freight movements for industrial customers and on interchange traffic. CMQ considered restoring crude-oil service in January 2016, but the proposal did not proceed because market conditions made the business unattractive. The company also broadened its operating portfolio. In September 2015, the Maine Department of Transportation chose CMQ to operate the state-owned Rockland Branch between Brunswick and Rockland. CMQ took over on January 1, 2016, replacing Maine Eastern Railroad. Its proposal did not continue Maine Eastern’s passenger excursions, so the branch became focused on freight service. In 2017, CMQ began operating the former Norfolk Southern Hannibal Subdivision in Ohio. The line served industrial facilities associated with Fortress, including the former Long Ridge Energy Generation Facility in Clarington. Locomotives assigned to the work included CIT-owned SD40-2 units, and operating crews were sent from Maine on rotating assignments. This Ohio operation was geographically separate from CMQ’s principal Maine-Quebec system. On November 20, 2019, Canadian Pacific announced that it would acquire CMQ. Canadian Pacific chief executive Keith Creel said the acquisition would provide a more complete coast-to-coast Canadian network and increase the company’s presence in New England. The purchase also allowed Canadian Pacific to regain several routes that had previously been part of its system before being sold to predecessor railroads and later consolidated under CMQ. Canadian Pacific completed the acquisition on June 4, 2020, after which CMQ ceased to operate as an independent railroad brand. The Rockland Branch remained a separate operational issue after the acquisition. In late August 2021, Finger Lakes Railway was announced as the incoming operator, and the Surface Transportation Board approved the transfer. Dragon Cement, the branch’s largest shipper, subsequently stated that it would stop shipping cement from its Rockland facility by the end of 2021. Because cement movements formed most of the branch’s revenue, the decision threatened the economic basis of the rail shuttle service. The former CMQ network and assets therefore continued under new ownership or operating arrangements, but Central Maine & Quebec Railway itself remained a historical, defunct brand after the Canadian Pacific transaction.

Products and positioning
A privately owned regional and short-line freight railroad focused on maintaining and operating a cross-border industrial rail network in northern New England and Quebec.
Rail freight transportation · 2014
Cross-border freight rail service
CMQ’s principal offering was regional freight transportation across a network linking Maine, Quebec, and Vermont. The railway hauled traffic for industrial customers and connected with major and regional carriers at interchange points including Saint-Jean-sur-Richelieu, Sainte-Rosalie, Lennoxville, Northern Maine Junction, Brownville Junction, Millinocket, Brunswick, and Newport.
Short-line railroad operation · 2016
Rockland Branch freight operation
Under a Maine Department of Transportation contract, CMQ operated the state-owned line between Brunswick and Rockland from January 2016. The operation emphasized freight, including a cement shuttle associated with Dragon Cement, and did not continue the passenger excursion program previously offered by Maine Eastern Railroad.
Industrial rail operation · 2017
Hannibal Subdivision operation
Beginning in 2017, CMQ operated the former Norfolk Southern Hannibal Subdivision in Ohio for Fortress-related industrial customers. The assignment was separate from the company’s principal Maine and Quebec network and used locomotives and crews assigned specifically to the operation.
Controversies
2013
Lac-Mégantic rail disaster involving predecessor railway
The July 2013 runaway crude-oil train derailment in Lac-Mégantic occurred under Montreal, Maine and Atlantic Railway, before CMQ was formed. The disaster killed 47 people and contributed directly to the predecessor’s bankruptcy and the later creation of CMQ. CMQ was not the operator at the time of the accident.
