Seacoast,
The guys have done a good job recommending the Books, sense you are new to Tin Plate I will give you this advise, there are some companies modern track that do not accommodate Tin Plate Trains very well, so before you set up a Tin Plate layout become familiar with the track you plan on using. The track and switches I recommend for trouble free constant running of all the different Tin Plate Trains are, Lionel Conventional Tubular with 711/072 Switches lots of power need for this set up, Original K-Line Tubular Super Snap Track and Switches, new low voltage Tubular RMT Super Snap Track & 072 Switches and FasTrack with Low Voltage 054 and larger Command Control Switches.
Welcome to the Tin Plate world and have fun!
