The Boston and Lowell Railroad was established in 1830 as one of the first rail lines in North America. The first track was completed in 1835, and freight service began immediately connecting Boston to the newly established town of Lowell, which had just 6,400 residents at the time (compared to Boston which had 10x that). The original Boston depot was a modest structure, but after the Civil War, it was decided that a new station connecting two of the most important industrial cities in Massachusetts, should be built. Architect Edgar Allen Poe Newcomb and his father’s firm, L. Newcomb & Son, was selected to design a new station on Causeway Street. The French Second Empire masterpiece was built between 1871-1878. Inside, the concourse was lined with oak walls and marble flooring. The depot was added onto in 1893 and incorporated into a Union Station of multiple former lines, and ultimately demolished in 1927 for the first North Station.
