Hybrid PF/9V Systems

Following up on my previous article introducing LEGO’s 9V system and their Power Functions (PF) system, I’m going to go a little more in depth about building hybrid systems that utilize both PF battery packs and 9V train track. I’ve developed and iterated through several different systems that combine the best of both and have come up with several easy to implement systems.  Anyone with a few dollars, a volt meter and a soldering iron can hack together one of these hybrids in a matter of hours.

Piggy Back Ride

Video back then wasn’t what it is today, but even this short clip shows what an ingenious build this was.

Understanding LEGO® track geometry, and best track layout practices, can be a little tricky for fans new to the hobby. And even veteran builders can learn new things about how the various LEGO track pieces can be used to create new layouts. Fortunately Hungarian LEGO train builder Ashi Valkoinen has written an excellent PDF on LEGO track Geometry, which we are happy to share with our readers here on Brick Model Railroader. It’s a great resource for any one who wants to understand better how to work with LEGO track.

You can read the PDF here, or you can download Ashi’s original PDF on LEGO 9v Train Track Geometry from the link bellow.
