Guagemaster

I recommend Gaugemaster because it has shelves full of products from: metcalfe, hornby, skalectrics, airfix, and also corgi. As you come in you'll find a small layout with a selection of tunnels. You press a button and a train darts from one tunnel to another. They even sell magazines including my favourite, hornby magazine. There is even a layout with moving cars and trains.
It has tons of inspiration and the shopkeeper is shore to give you advise if needed. Okay are you ready for this, the shop is literally next to a station! This means that you can get on the train at wherever ( preferably in west sussex but there's probably more in England and maybe even other country's, I'm 99% shore there isn't though) and stop somewhere for lunch. Then you can ride to the shop ands buy or look around! If you want to go to gaugemaster website, click the link (the blue gaugemaster). I'm really do you recommend you go to gaugemaster great place to learn about new model railway and I think I  have told you, GO THERE SOON!
