Here is the plan for a nonsensical Steampunk style locomotive for the background of  azraelseraph 's commission (I'm getting through all these, slowly but surely I swear)

Based on the principle that he wanted his steam-punk self standing at a station with a musket I immediately thought of the favourite past-time of Victorian gentlemen: hunting dangerous and rare animals to extinction wantonly with heavy ordnance. This piece of kit doesn't come much heavier at about 4 times the size of what should be technically possible.
