York's National Railways Museum is exactly what it says, a treasure trove of all things railway since their invention, right down to the Stephenson's Rocket.
The main hall contains a variety of the big steam engines, coaches (there's a royal coach), and it includes the Hogwarts train and platform 9 3/4 from the Harry Potter films.
But there's so much more, covering all the things that support a rail system. Signals and switching, signs, artwork, luggage trolleys, uniforms, lighting, furniture, it's all there. I'm told the museum has 1,000,000 items in its possession
You can even look in a workshop where engines are maintained. The Flying Scotsman was being worked on during my trip.
Admission is free, but you can contribute a voluntary nominal amount, to support the upkeep. Normally, something as large and comprehensive as this is only found in London, but York is the perfect place for it, and it's worth the upkeep.
Speaking of large, you can easily spend two to three hours here, so the centrally located cafeteria is a welcome part of the experience.
Naturally, there's a museum shop, but there's also a separate research area where you can look up or enquire on little known facts, publications and so on.
Group bookings are available, which include discounts at the shop, and other benefits.
