In the station at the Alberta Railway Museum is a permanent display of telegrapher's equipment, in an office set up as it would have been in the 1920s and 1930s. The Museum also has the most extensive collection of telegraphy equipment in Canada, donated by APRA member Ab Krauter. Ab was also a member of the Morse Telegraph Club, Edmonton Chapter.
The video below, while unrelated to telegraphic activities at the Museum, illustrates very well how a telegraph key is operated.
