The Batavia Air Line is a paper railroad that the D&H spun off to maintain trackage rights on the Groveland Secondary & Industrial Track (Attica to Retsof/Greigsville, plus a spur up to Batavia) when Conrail decided to abandon the line in 1988.
In 2023, the Batavia industrial track, which had been seeing slow but steady traffic gains, was electrified, leaving the Groveland Secondary to be operated by one of the D&H’s dual power locomotives in diesel mode.
The Retsof salt traffic was never the greatest (when G&W management did their own go big or go home moment, they started preferentially routing salt trains on their own collection of railroads. The D&H managed to hang onto some of the salt traffic to Buffalo for a long time) and by 2026 the Groveland Secondary to Retsof was out of service and up for abandonment.
