GN-NP Archive

This information began as a snapshot of the interlockings that existed on the Great Northern System in 1935, including GN's Canadian interests. It now includes some newer installations as well. Please recognise that this is a work in progress and incomplete. By this time there had been towers and other interlockings built, modified and closed. Some of the locations listed have no closing date known to me. Some of these may have been closed by 1935. The Canadian information is very hard to obtain and the group I am involved with this research has provided a lot of the information. Certain individuals have helped out a great deal, notably Hudson Leighton. Any additions/comments/corrections would be very much appreciated.
