| Here is the inside of the front cover of a 16-page booklet published by the Pennsylvania Railroad entitled "Information for the Public and Employes." It was issued originally during September of 1924. Photo Caption: "The Call to Duty. Engineman at home signing book presented by the caller, summoning him to his run. While the telephone is extensively used for this purpose, special messengers with their 'wheels' still perform much of the work." |
