Also known as the Rock-A-Bye Baby Railroad, the Rockaway Valley Railroad crossed Tingley Road on its route from Whitehouse Station to Watnong. Beginning in 1892, it stopped in the Mendhams at Ralston, Mountain Road, Pitney Farm, Brookdale, and Day's Mill. It connected farms and industry to markets in Newark and New York City and carried local residents to schools and shops in Morristown. Poor construction and bad luck ended rail service in 1913 when the company succumbed to debt.
