Good day! It's great to hear that you're getting serious about HO trains—it's a rewarding and creative hobby. For learning the EZ Track system and diving into Digital Command Control (DCC), I recommend the book "DCC Guide: How to Select and Use Your Command Control System" by Don Fiehmann. It provides an excellent introduction to DCC, covering how to set up, program, and operate your system effectively. Additionally, the Bachmann EZ Command System manual is a helpful resource for understanding the basics of EZ Track and its integration with DCC.

As a fun complement, consider exploring 3D train simulation games like Trainz Railroad Simulator or Railroad Tycoon. These games let you design and operate virtual railroads, offering inspiration and creative ideas that can translate into your HO train layouts. Happy railroading!

Check Specialty Hobby Retailers
Many hobby shops carry or specialize in Bachmann On30 rolling stock, often stocking items that are out of production elsewhere. Try:
TrainWorld: Known for a wide range of model train supplies, including Bachmann On30.
MB Klein (ModelTrainStuff): Frequently carries passenger cars, including older and hard-to-find stock.
Nicholas Smith Trains: They have an extensive collection of rolling stock and accessories.
