I forgot to mewntion that one of my Heroics and Ros purchases was a Russian WW2 Armoured Train! It was only £8 for the engine and loads of cars (AA, T-34 turrets, artillery as well as some flat bed trucks).
I'm hoping to run a scenario where the said train is attacked by the Wermacht in deepest Russia - with the Soviet forces despatched to defend it (with some dive bombing etc. thrown in).
After I've painted it, of course. But as its 6mm, this will take about a day!
