You can start your railway collection with a simple push-along train or battery operated ones, adding extra rails, points and crossings as you go. The push-along train can be converted to battery power and the battery powered trains to electrical power when you are ready for it, so you do not have to discard one system to advance to another. A special LEGO Railways Ideas Book is crammed with ideas for models and track layouts to help you get the full play value from your trains.
