A simple modern cantilever style bus shelter with timetable board for your modern image railway layout. This is a longer shelter, such as you might find at busier stops. 2.5m tall, 2m deep, 5m long.
The middle pole is longer than the others, drill a hole to fix it to the baseboard. After painting you'll want to glue some acetate to the back as glazing. There are tabs on the poles to make this easier.
