I belong to the rare species of US prototype TT scale model railroaders. However, I do not have a big layout but make small layouts and dioramas. My first US layout, I started in 2006. It's a diorama style but operational layout the design of which follows the 'long and narrow' principle. With a size of just 150 cm x 15 cm (59" x 5.9"), it's a real micro layout. It consists of two modules that can be folded into a transport box of which the backdrop plates form the sides. This way, I can carry the layout even in public transit.
