The Portland Terminal Company (reporting mark PTM) was a terminal railroad notable for its control of switching activity for the Maine Central Railroad (MEC) and Boston & Maine (B&M) railroads in the Maine cities of Portland, South Portland, and Westbrook.
The Maine Central Railroad (MEC) came under the control of the Boston & Maine Railroad (B&M) in 1884. The New Haven Railroad secured control of the B&M in 1907, and the Portland Terminal Company was formed in 1911 as part of the New Haven's consolidation of New England transportation facilities. Portland Terminal Company became a subsidiary of MEC while B&M was in financial difficulty in 1914.
PTM's activities were vital to Portland's role as a winter seaport receiving Canadian products from the Grand Trunk Railway for export to Europe. Shipping from Portland declined sharply as Canadian exports were routed via the Maritime ports of St. John, New Brunswick and Halifax, Nova Scotia following nationalization of the Grand Trunk in 1923. Exports from Portland declined from 600,000 short tons (536,000 long tons; 544,000 t) per year in the early 1920s to 21,000 short tons (18,700 long tons; 19,100 t) per year during the worst year of the following depression. In the decade following World War II, PTM operated on 40 miles (64��km) of main lines and branch tracks, 84 miles (135 km) of yard tracks, and 18 miles (29 km) of industry-owned tracks. PTM was acquired by Guilford Transportation Industries in 1981, and continues as a subsidiary of Pan Am Railways.
Portland occupies an Atlantic coast peninsula between Back Cove to the north and the Fore River estuary to the south. The peninsula is protected from North Atlantic swells by the islands of Casco Bay. Back Cove was too shallow for 20th century ocean commerce. Portland Harbor is the seaward portion of the Fore River estuary.
Grand Trunk Railway from Montreal entered Portland from the north via a long trestle over the mouth of Back Cove. The Grand Trunk yard and wharves occupied the seaward end of the Portland Harbor waterfront along the north shore of the Fore River estuary. This line became the Berlin Subdivision of the Canadian National Railway when the Grand Trunk was nationalized in 1923. Access to the Portland waterfront ended when the Back Cove trestle burned in 1984; and the line to Montreal was sold to a short line operator in 1989.
Maine Central Railroad Mountain Division from St. Johnsbury, Vermont entered Westbrook from the northwest paralleling the old canal along the Presumpscot River. The Mountain Division was abandoned in 1983.
Boston and Maine Railroad Worcester, Nashua and Portland Division from Rochester, New Hampshire entered Westbrook from the west. The Boston & Maine discontinued passenger service in 1932 and through-freight service in 1934. The line operated as the Sanford and Eastern Railroad from 1949 until abandonment in 1961.
Union Station had eastern and western yards along the Boston to Bangor main line between Rigby Yard and Yard 11. The PTM assembled trains in these yards and added mail and express cars to through trains. Following a 1933 joint operating agreement between the Maine Central and the Boston & Maine, passenger trains from Bangor and points east to Boston or Worcester, Massachusetts and points south ran through Union Station with pooled equipment like the Gull and the Flying Yankee. Other Maine Central and Boston & Maine passenger trains originated or terminated at Union Station. Grand Trunk trains originated or terminated about 2 miles (3.2 km) east of Union Station without using Union Station. Union Station was razed in 1961.
Yard 1 served PTM Wharf 1 on the Portland Harbor waterfront along the north shore of the Fore River estuary upstream of Yard 2 and downstream of yard 8. Wharf 1 had water frontage of 1,000 feet (300 m) and included a 100,000-square-foot (9,300 m2) warehouse for handling package cargo interchanged with ships of up to 30-foot (9.1 m) draught.
Yard 2 served Portland Harbor waterfront wharves along the north shore of the Fore River estuary upstream of the Grand Trunk wharves and downstream of Wharf 1. Yard 2 became the local interchange with the Grand Trunk Railway after 1947.
Yard 3 along the original Boston & Maine eastern route served the South Portland waterfront of the Fore River estuary including PTM Wharf 4, the New England Shipbuilding Corporation and the Portland-Montreal Pipe Line terminal.
Yard 5 car storage inland of Yard 8.
Yard 7 served distribution warehouses and light industries along the south shore of Back Cove. Yard 7 was the interchange with the Grand Trunk Railway until the Portland Junction connection was severed during construction of a highway bridge over the mouth of Back Cove in 1947.
Yard 8 served PTM Wharf 3 on the Portland Harbor waterfront along the north shore of the Fore River estuary upstream of Yard 1. Wharf 3 had water frontage of 1,500 feet (460 m) designed for handling bulk commodities from ships and barges of up to 30-foot (9.1 m) draught. PTM #1601-1800 30-foot USRA hopper cars carried coal from this wharf to local industries. The wharf included a storage shed for 4000 tons of china clay transported to the Westbrook paper mill in PTM box cars. Maine Central 35000-series USRA 50-ton, 40-foot (12 m), single-sheathed box cars were repainted PTM #2001-2150 in 1956. Maine Central 4000-series 40-foot (12 m) steel box cars were repainted PTM #50-54 in 1966. Wharf 3 was closed about 1970. Yard 8 included the first piggyback ramp served by the Maine Central Railroad.
Yard 9 was the old Fore River Yard on the Mountain Division adjacent to the north shore of the Fore River estuary upstream of the dredged channel. Rigby Yard was enlarged to eliminate most activity in Yard 9.
Yard 10 served PTM's Thompson Point shops adjacent to the Mountain Division upstream of Yard 9. Thompson Point shops built 49 flat cars, 40 box cars, 3 cabooses, a baggage-RPO and a RPO-smoking car for the 2-foot (0.61 m) gauge Bridgton and Saco River Railroad and Sandy River and Rangeley Lakes Railroad between 1912 and 1917.
Yard 11 served large grocery distribution warehouses at Deering Junction where the Boston & Maine WN&P division joined the Maine Central main line to Bangor.
Rigby Yard (Yard 13) was built in 1922 at the South Portland junction of the eastern and western routes of Boston & Maine's Portland division. Rigby became the busiest New England rail yard north of Boston as car storage and locomotive servicing facilities were eliminated from older yards in Portland. Maine Central and Boston & Maine freight trains originated or terminated in Rigby Yard. Yard 12 became the interchange point for Sanford and Eastern trains.
Blue Rock Quarry was on the Mountain Division between Westbrook and Portland. Bethlehem Steel delivered 70-ton, 40-foot PTM hopper cars #101-150 in 1956 to replace the old USRA hoppers for coal loading. These cars were used for ballast service as heating oil minimized coal demand. Cars #101-122 were fitted with side extensions for off-line wood-chip loading on the Maine Central Railroad.
