If any of you are into legos and have a 3D printer this website has some awesome things to print https://www.4dbrix.com/

Also you can buy full train sets (that are bigger than the lego sets) from https://www.bluebrixx.com/en/bluebrixxspecials/trains

Im not saying you need to cover your whole house in lego trains. but thats what im going to do :D
