Armored Rail Cruiser "The Angry Dragon"

 Known as The Angry Dragon to the locals and the common soldiery, and the Armored Cruiser to most military commanders in the province, this train is a coveted and feared weapon, often fought over by all sides. At one point or another the train has steamed alongside all the major powers in the province, from the Japanese, to the Warlords, the Nationalists and even the White Russians. Shifting sides when captured or overran, no commander is willing to scuttle her, they rather squabble than take her out of play. She may be ours this week, theirs the next, the Bolsheviks the following, but by next month, she'll be ours again! 6 weeks at most..  

Under Japanese Command, patrolling somewhere deep in the countryside.

Being an armored rail cruiser, and not a traditional armored train, the Angry Dragon doesn't require a dedicated engine and tender. Instead two fiat diesel engines power the front and rear trucks, or was it rear and front trucks? Either way, the train is entirely self propelled, but its smaller size limits it's capabilities and cruising range, effectively stranding it in the rural province. Despite it's shortcomings, no commander would complain having it's fearsome firepower available to his men, twelve water-cooled machine guns, and two 57mm quickfire guns can turn any battle in your favor, especially when your enemy are armed with rifles and the odd mountain gun.
