This image was taken at one of the events I used to go to at the Bodmin and Wenford Railway in Cornwall. The original post the photograph is taken from can be found here: https://steemit.com/hive-185836/@daverobe/the-world-of-xpilar-b-and-w-photography-and-art-contest-week-064-steaming-off.

In the picture I have submitted here, you can see a soldier loading his gun on the train preparing for the (mock) battle ahead.
