The idea of these guns being workers could install track torpedoes without having to dismount to do it. So there was an explosive charge in the gun to propel the explosive torpedo to its desired location. Unless it bounced off a rail or some ballast and went amiss.
If you watch any of the rest of this video, you can see that working the railroad in those days was for real men. Especially track work.
