Caldwell station opened with the construction of the Caldwell Branch of the New York and Greenwood Lake Railroad. The original proposed service through Caldwell was the Caldwell Railroad, a company founded in March 1869 for the construction of a railroad between Montclair and Caldwell. Construction began in 1872 of the railroad. However, work on this route was suspended in 1872 due to the inability to complete a tunnel through Montclair and nearby Verona. About of the tunnel was left uncompleted. The railroad was built in 1891, with the route via Great Notch station in Little Falls. As part of the construction, a depot, measured at, was built for the terminal of the new railroad. Service on the railroad began on July 4, 1891. Service, one year later, was extended to nearby Essex Fells. The station was replaced in 1904 as part of the construction of the Morristown and Caldwell Railroad. Construction of this new station cost the Erie Railroad $20,000. The new station would do the work of the Erie Railroad and the Morristown and Caldwell Railroad. This new depot was measured at. On July 4, 1904, thirteen years after the commencement of service through Caldwell, the first train of the Morristown and Caldwell crossed through the borough. The old station, built in 1891, was moved across the tracks, serving as a freight house. On January 9, 1905, the passenger station built at the nearby Verona station caught fire. The depot, along with its contents, were burned and lost. The Erie Railroad decided to take the old station at Caldwell, serving as a freight depot, to become the new passenger depot at Verona. In February 1905, the snow-covered ground served as an opportunity to move the depot. With 12 horses, the old freight depot was moved up Bloomfield Avenue on rafters to Depot Street and Personette Street. This depot burned down in the winter of 1962. In 1902, the Monomonock Inn, a local hotel and resort, opened, which helped influence the growth of Caldwell. By 1916, the inn itself had its own station on the Caldwell Branch. The Monomonock Inn, located on Bloomfield Avenue, was closed and razed in 1940, to be replaced by local housing and an A&P grocery store. Local streetcar service, which ran next to the Caldwell station on Bloomfield Avenue ended in 1952. The borough of Caldwell purchased the depot in 1965 from the cash-strapped Erie Lackawanna Railroad. The borough razed the depot on August 6, 1965. Service at Caldwell station ended on September 30, 1966, when multiplebranch lines of the Erie Lackawanna were discontinued.
