To go with the coaling tower, I made this water tower. As can be seen from the pictures below, the water tank is made from stained 1/16 plywood planks around a styrene core.
The 'steel' bands around the tank are made from cotton. The water hose is a piece of copper mains electrical cable with the insulation still attached.
The structures legs are stained Ramin strip wood, all attached to a styrene base which will be sand coverd to match the baseboard.
