Lego Trains, like Lego itself, have long had a history of being modified. Lego was made to be modified, and many people do it as a hobby, kids and adults. Often, these builds reflect local real railways, like the UK in this example. I am personally very partial to these model railways, as I am to British railways as a whole, and they both look amazing and are often accurate. My favorite part of the model British trains is being able to see them roll through the intracate brick-built landscapes of the scenic countryside or built-up city.
