The Portsmouth and Concord Railroad was formed 1845. In 1846 before construction even started the railroad was granted two branch lines, one to Manchester and the other to Hooksett. In 1847 construction started in Portsmouth and had reached the Concord Railroad in Bow, in what became Bow Junction in 1852 (Bow Junction, is now the present day location of Blue Seal). Due to financial troubles the two branch lines never materialized as the railroad struggles to make a profit.
In 1855 the Portsmouth and Concord Railroad was turned over to its creditors and a new railroad was formed called the Concord and Portsmouth Railroad (city names reversed). Financial troubles continued and in 1858 the Concord Railroad leased the Concord and Portsmouth Railroad for 5 years. In 1862 the Concord Railroad extend its lease for 99 years at which time the Concord Railroad, using the license granted to the Portsmouth and Concord Railroad in 1846, built the two branch lines, one from Candia to the Manchester and Lawrence Branch and the other between Hooksett and Suncook. Upon completion of the two branch lines the segment between Candia and Suncook was abandoned.
In 1858 the Concord and Portsmouth Railroad lease was transferred to the Concord and Montreal Railroad when the Concord Railroad merged with other Railroads to form the C&M. In 1895 the lease transferred to the Boston and Maine when the Concord and Montreal was leased to the B&M. In 1944 the B&M purchased the Concord and Portsmouth Railroad and a year later it was dissolved. After the Candia, Suncook abandonment the rail line became known as the Manchester and Portsmouth Branch of the Concord Railroad and later the B&M Railroad. Service between Manchester and Rockingham Junction ended in 1982. In the late 1980’s the rails were removed between Manchester and Rockingham Junction. Today a small segment between Rockingham Jct. and Portsmouth is still in service, owned by the B&M Railroad and operated by Springfield Terminal Railway both are subsidies of Pan Am Railways. The section between Rockingham Jct. and Manchester is owned by the state and is now a rail trail.
Back to 1863: Just as the Concord Railroad was getting ready to abandon the segment between Candia and the junction of the new feeder line from Hooksett in Suncook the state granted two charters to build a rail line from Suncook to Pittsfield and Pittsfield to Alton Bay, where it would join up with the Dover and Winnipesogee Railroad (The spelling of the lake was later changed to the present day spelling). Construction started in 1869 with service to Pittsfield, starting the same year. Due to financial troubles and the Civil War, construction between Pittsfield and Alton Bay was put on hold. The extension to Alton Bay never materialized but in 1889 the line was extended to Center Barnstead.
In 1895 the Suncook Valley was leased to the Boston & Maine the same day the Concord & Montreal Railroad was leased to the B&M. In the 1920’s the B&M petitioned to abandon the Suncook Valley and in September 1924, the Suncook Valley Railroad became New Hampshire’s, first independent short line. The Suncook Valley Railroad abandoned the track between Pittsfield and Center Barnstead in 1947 and in 1952 the B&M embargoed the interchange track do to deteriorating conditions of the Merrimack River Bridge, south of Bow Junction. After the embargo the Suncook Valley abandoned all operation.
Peter Dearness of New England Southern Railroad told me a while back that the feeder route between Hooksett and Suncook was abandoned sometime in the 1920’s or 30’s after the bridge over the Merrimack River was washed out in a flood. Since Suncook could be serviced from Bow Jct. the bridge was never rebuilt. Only the stone abutments and stone pillars of that bridge survive today. (Located by Edgewater Drive in Hooksett.)
I believed the bridge up by Bow Junction also supported a trolley line (on its own track) that ran between Suncook and Concord.
I just looked for the first time, but the ROW between Candia and Suncook (right up to what later became the “switch back” for the Pittsfield Branch [the Blueberry Express]), is still visible on Google Map’s satellite imagery.
It takes real skill to choke on air, fall up the stairs and trip over nothing. I have those skills.
