Today, Canadian Pacific Kansas City owns the line.

The Boston, Hoosac Tunnel and Western Railway was incorporated in 1877 to build a new railway line linking western New York with Boston, Massachusetts, via the Hoosac Tunnel.

The D&H's remaining passenger trains, including the Laurentian, were re-routed over the freight bypass.
