Hi,
I scratchbuilt a Russian armoured train for wargaming the civil war.
I used PIKO H0 Locomotive and train chassis. I made the armour from 0,5mm polystirol sheet.
The guns are from sprues frame.
I painted a unit of reilroad workers. I converted them from Strelets Crimean war figures:
You can see more photos and the phases of biulding here:
