Overview
The Middlesex Railroad was an early American street railway company serving the Boston, Massachusetts, area during the middle and late nineteenth century. Created by an act of the Massachusetts legislature on April 29, 1854, it was intended to connect communities in or near Middlesex County with Charlestown and central Boston. Its proposed system called for a route from one or more points in Somerville to Charlestown Square, now known as City Square, followed by a continuation over Warren Bridge into Boston and as far as Haymarket Square, with a return to Charlestown over Charles River Bridge. The Somerville portion was not built by the Middlesex Railroad; its construction rights were eventually conveyed to the Somerville Horse Railroad. Construction of the Charlestown and Boston portions began in October 1856. The first car operated on March 6, 1857, traveling between Charlestown Neck and the vicinity of Stillman and Charlestown streets in Boston, an area now associated with North Washington Street. In its early operating period the company did not directly carry or manage passenger traffic. Instead, its road was leased to the Malden and Melrose Railroad, which supplied equipment and handled operations. The Middlesex later acquired a controlling interest in the Malden and Melrose, strengthening its position within the region's developing network of horse-drawn street railways. At the end of March 1862, the Malden and Melrose agreed to provide the Middlesex with a forty-two-year grant for exclusive use of its tracks. Through related leases, the Middlesex also gained control of lines associated with the Medford and Charlestown Railroad, the Somerville Horse Railroad, and the Boston and Chelsea Railroad. These arrangements were not all permanent or exclusive: use of the Boston and Chelsea line was soon transferred to the Lynn and Boston Railroad, while operation of the Somerville Horse was later divided with the Union Railroad. Nevertheless, the leases and consolidations made Middlesex one of the principal street railway companies in the Boston area. Passenger traffic expanded substantially as Boston's urban and suburban population grew. The company reported approximately 2.8 million passengers in 1865, excluding passengers counted by lessor lines. That figure rose to about 4.4 million in 1875 and 7.6 million in 1885. These figures illustrate the importance of horsecar railways as an everyday urban transportation system before the widespread adoption of electric streetcars. The company broadened its corporate structure through consolidation. In 1870, Middlesex consolidated with the Suburban Railroad Company. In 1880, it consolidated with the Medford and Charlestown Railroad. The lease of the Somerville Horse Railroad was assigned to the Union Railroad in 1876, reflecting the continuing redistribution of operating rights among Boston-area street railway companies. In August 1886, Middlesex and the Highland Street Railway agreed to consolidate and form the Boston Consolidated Street Railway. Charles Edward Powers of Middlesex became president of the new company, while Moody Merrill of Highland became vice president. The resulting system was the second-largest street railway operation in Boston, behind the Metropolitan Street Railway, and its Highland lines extended service southward into the South End and Dorchester. In 1887, the West End Street Railway acquired a controlling interest in Boston Consolidated as part of a broader effort to unite Boston's street railway companies under one organization. The Middlesex enterprise was formally merged into West End on November 12, 1887, ending its independent corporate existence.
History
The Middlesex Railroad was established by Massachusetts legislative act on April 29, 1854. Its original corporators were Asa Fisk, Richard Downing, and David Kimball. The proposed route was designed to connect Somerville or nearby points with Charlestown Square, cross Warren Bridge into Boston, reach Haymarket Square, and return toward Charlestown via Charles River Bridge. The Somerville segment was not built by Middlesex and its construction rights later passed to the Somerville Horse Railroad. Work on the Charlestown and Boston portions began in October 1856. On March 6, 1857, the first car ran from Charlestown Neck to the corner of Stillman and Charlestown streets in Boston, now associated with North Washington Street. During its early years, the company leased its road to the Malden and Melrose Railroad, which supplied vehicles and managed service. Middlesex subsequently obtained control of Malden and Melrose. In March 1862, Malden and Melrose granted Middlesex exclusive use of its tracks for forty-two years. Related leases also brought the Medford and Charlestown, Somerville Horse, and Boston and Chelsea railways within the company's sphere, although the Boston and Chelsea operation was soon transferred to Lynn and Boston and the Somerville Horse operation was later divided with Union Railroad. By the 1860s, Middlesex was one of four major street railway companies in the Boston area, alongside the Metropolitan, Union or Cambridge, and South Boston systems. Its reported annual passenger totals increased from approximately 2.8 million in 1865 to 4.4 million in 1875 and 7.6 million in 1885, excluding passengers recorded by lessor lines. The growth reflected the increasing role of horsecar railways in connecting Boston with surrounding neighborhoods and municipalities. Corporate consolidation became central to the company's later history. Middlesex consolidated with the Suburban Railroad Company in 1870 and with the Medford and Charlestown Railroad in 1880. In 1876, the lease of the Somerville Horse Railroad was assigned to Union Railroad. In August 1886, Middlesex and Highland Street Railway agreed to consolidate as Boston Consolidated Street Railway. Charles Edward Powers of Middlesex became president and Moody Merrill of Highland became vice president. The new company ranked second among Boston's street railway operators after Metropolitan and gained routes extending south into the South End and Dorchester. In 1887, West End Street Railway acquired control of Boston Consolidated while pursuing a wider consolidation of Boston's streetcar companies. Middlesex was formally merged into West End on November 12, 1887, ending its independent existence.

Middlesex horsecar service
The company's principal offering was horse-drawn street railway transportation. Its own route connected Charlestown with Boston, while leases and corporate relationships extended its reach toward communities in Middlesex County and other parts of the Boston metropolitan area. The service was designed for regular passenger movement between outlying communities, Charlestown, and central Boston rather than for long-distance intercity travel.
