It's size and the fact it can be transported and taken to events around the country, it can even fit inside a normal house living room, it has plug in power do can be easily connected and disconnected, it has a full vintage railway theme, although its not quite finished yet.
it has opening windows which have been fitted later and new year it will have a new door with opening window, its due for a full enamel paint in April for more vintage inspired paint colours (Green and cream) my plan is that it will be fully finished in April 2023
