Platform 9 3/4 is probably the most famous train platform in the world. This decal is a single colour vinyl cut out that is very easy to apply and will last up to 5 years in both hot and cold climates. The platform was mentioned in the first movie, when Harry, the Weasel family and lots of other wizard kids had to travel to Hogwarts by train. The train could only be accessed from a platform that couldn’t be seen from the normal platform so the kids needed to run through the wall with their trolleys. These stickers will adhere to any smooth surface.
