For high quality: http://www.youtube.com/watch?v=KcTPdCQYMeU&fmt=18 Here from my archives is a short video of the 1st OO model railway layout I built ten years ago. The base board was 8 foot by 4 foot. The track work was on 3 levels.I set out to see what I could back in on a base board of this size. If you have any questions, i'll do my best to answer them.Thank you.
