If you are into semaphores and wigwags, or just enjoy the former SP's Siskiyou and Coos Bay Lines, this is the list for you. The Central Oregon and Pacific Railroad has more in service semaphores than any other line in the U.S. The CORP is made up of mostly GP38's, a handful of SD40-3's, a pair of SW-1500's and a couple of GP40's mated to their two slugs. UP power is used to run the big train between Roseburg and Eugene. Enjoy! And if there is any way of improving, let the list owner know.
