BN train AA241 is westbound near Thompson Falls, MT pulling a long string of PGEX gondolas in September 1991. In 1987 the Montana Rail Link took over operation of the former Northern Pacific mainline between Sandpoint , ID and Jones Jct. east of Billings, MT. Along with the track, the MRL also inherited the old NP upper quadrant semaphore signals. Photo by Nick Krantz.
