I completed work on the Polish armoured train for Flames of War sometime last week. It was a massive project that took weeks of work but the end result is a fantastic piece by itself or standing amidst an army on the table top.
The most challenging aspect of painting this model is the sheer number of rivets that adorn the model. The rivets add much detail to the overall model and therefore must be emphasized. There is a great painting article for this model in Wargames Illustrated 281 and I'd recommend reviewing it if you are planning on working this model.
The locomotive and cars are massive in size. The locomotive measures 6 inches long, the artillery cars measure 7.5 inches long, and the assault car is 4.5 inches long. The sheer size of the pieces translated in some cases to a single color on a single car for one evening's painting session.
I found that wearing a rubber glove on the hand holding the model prevented the paint from wearing off due to the natural oils on my hands. In all of my years of painting, I've never known that it was body oil that caused that, simply thinking that it was a matter of being handled and rubbed off. A big thanks to Jeff for explaining that to me!
In addition to the train, I've complete a unit of tankettes to go along with my Polish forces. These models are quite small when placed next to the smallest of Flames of War tanks.
The next project I'm working towards is the painting of a number of Polish Infantry Platoons. If you are heading to Historicon, you'll be able to see the army in action at the Flames of War National tournament, including the train!
