Caption: My view heading north on a work train and approaching the short Azouzetta tunnel at mile 598.5. The tunnel at one time had doors on the portal to help prevent icing inside. The doors were protected and opened by a watchman,he inspected the tunnel and then would authorize trains through. This was the only tunnel on the Chetwynd subdivision and after the right of way was re-surveyed the mileage was corrected to mile 597.9. Another Kodak Instamatic Moment from long ago.
