Beautiful picture with the Royal Hudson and the FPA-4. We actually had these just as shown for 8-9 years in service and could be seen frequently on trains and rails that are also now long gone. ( It may not have been a FPA-4, likely just an FA1 or FA2)
Beautiful in the CNR green and gold and side by side with steam that thankfully never saw the noodle or CP's multimark.
Business was very brisk across the land in Canada throughout the fifities. Diesels came fast and furious but steam was needed and kept in service to handle the sheer volumes.
In Penny's picture it is very pleasing to see they kept the distinctive bell on the roof.
I am so grateful I got to actually see scenes in real frequent service involving these locomotives ..and for quite some time, although looking back now, all too short a period of time.
