Guns for Patiala?

I have not had much time recently to work on anything, especially the monorail. This weekend is Father's Day weekend so I will be spending some time working on projects. Last night, I laid down a little more dirt on to the road portions of the rail sections and started thinking about further detailing. I will be using the track and trains mostly for VSF but rather just going with a reddish Martian sandscape, I decided to look at the terrain of the prototype in Patiala. Google brought up a huge number of clothing images - very strange but not much in  the way of landscape shots.  I was a little put out until I found this Wikipedia image. 

Yes it is a British WWI gun on a standard gauge railway and the only thing it has to do with the monorail is that Bhupinder Singh the Maharaja of Patiala, is looking at it. But - I am going to have to build one for the monorail - just maybe not quite so big.
