When time is very limited, I tend to reach for a quick, simple project. A building, couple figures to paint, simple layout scenic project, or a wagon. One of the nice things about modelling British O scale, is the vast array of kits available. Here's my latest build, a Caledonian Railway / LMS 12 ton Single Bolster wagon kit from Taff Vale Models. All white metal, it was a simple quick build which took 2 evenings. It awaits a trip to the paint shop for finishing. The white metal gives it good weight, very smooth running wagon.
