In light of the recent increased interest in armoured trains (particularly
their use in Egypt in 1882) I have a photograph of an
armoured train built and crewed by the Royal Navy. The caption for the photo
states that it was named H.M.S. Invincible, was commanded by Captain
Fitzroy, and was armed with a 40 pdr. gun and several Gatling machine-guns.
The locomotive appears to be an 0-6-0 outside frame tender engine, and its
boiler is "armoured" with spare track rails and boiler plate. The 40 pdr.
gun is fixed behind an armoured breastwork, and mounted on a standard
4-wheeled flat car. There appear to be two field guns (ships' landing guns?)
on a flat car further to the rear of the train.
