[9] That tunnel, and the railroad itself, is now owned by the Canadian Pacific Railway, whose Soo Line subsidiary purchased the rail assets of the Milwaukee Road in February 1985.

The CP also hosts Amtrak’s Empire Builder passenger train, though rail traffic is dominated by freight as the Tomah Subdivision.

The Soo Line had raised the bore of the tunnel 14 inches (36 cm) completed in 1993 to accommodate double stack traffic.

[10] The Soo Line considered excavating the hill or "daylighting" the tunnel bore.

[12] The CNW route, to Onalaska and Winona, is now mostly abandoned between Tunnel City and Medary.
