Association of Western Railways. Circular Letters No. 494-, 1949

This series consists of two sets of circulars. One set, from the Association of Western Railways [AWR], contains updates on agreements member carriers have entered into with various labor organizations. They also contain the text of the Agreements. AWR Circulars also contain information on decisions by various boards of adjustments based on interpretations of the previously mentioned agreements. Some of the circulars have attached correspondence, discussing how these interpretations affect either the carrier or their employees.

The second set of circulars come from the CNW itself. These circulars, issued by the personnel department, inform employees about updates and changes to the Rules, Agreements, and Schedules made between the carrier and the various labor organizations that represent the employees in negotiations. The circulars also interpret the changes, and inform the different classes of employees how the changes affect them.
