The Lakeside and Marblehead Railroad was a approximately 7-mile long line that was constructed in the 1880s to transport limestone from the quarries of Marblehead to the Lake Shore & Michigan Southern Railway (later New York Central System) mainline at Danbury. The railroad provided passenger service until 1930. In the 1950s, trucks began to take over the job of hauling limestone, signaling the death of the already financially-strained railroad. In 1964, the railroad ceased operations as a common carrier, and subsequently came under ownership of the Standard Slag Company. From 1974 to 1977, the line had fell into disuse, until an order came to haul by rail in 1978. It turns out, this would be the last order ever carried by the railroad. The final load of limestone was carried in 1980, the line abandoned, and the remaining locomotive stored.
After the Lafarge Corporation took over the quarry in 1989, renovations took place almost immediately. Tracks were pulled up beginning in 1991, and completed in 1997. The remaining diesel locomotive was also pulled from storage and scrapped on-site in 1995. A small engine house at Marblehead was razed in 1992, and the depot in 2002.
Today, a portion of the railroad is now in use as a walking path. The depot at Lakeside was restored in 1995, and still stands today. Apparently, some rail still exists on company property.
