Update: See where the railroad terminated by the ice houses at the Iron Mountain Railroad along the South Riverfront. See more of the ice plant in this post from October of 2021.
Coming through the ice house on the Lemp Brewery’s property, a rail line came down Potomac, and curved northward to hook up to the Iron Mountain Railroad.
While the middle of the curving path is now gone due to the electrical station, you can still see the gravel and asphalt right-of-way on either side.
