Building models is fun. Playing trains is fun too. With LEGO Railways you do both, so that’s double fun. And you can build LEGO people inside the carriages, just like they ought 10 be. You can have everything from an Electric inter-city express to a Battery train or even a push-along one. The new LEGO transformer/controller gives all the excitement of remote controlled points and signal lights. And the whole system is designed so that you can convert locomotives and rails from battery to electric whenever you want.
