This beautiful model train layout is built in N Scale. And, it's called "Grumpy Valley Mining". The name suggests a large model railway or a large industrial plant, but this model railroad was built on less than 1 square meter. It's a small world in N scale presenting a US coal mine and many lovingly crafted scenes.
Actually, there are more than 250 videos about model railroading and railway modelling, for example, on Dailymotion and YouTube. Please, visit also Pilentum's Facebook site.
