Back to trains!

I thought it was about time to get back to talking about important stuff....model trains! The topic of the day is Direct Command Control, or DCC.

DCC is cool because you can independantly control several locomotices on the same track. This means that if I want to recreate the model train wreck from the Adams Family show, I can.

The controller puts a steady voltage (around 14 volts) to the track, and lays a digital signal on top of that. Each locomotive has a decoder chip installed, which is programmed with an address. The chip, and hence the locomotive, will only respond to signals addressed to it.

The system I am using is a fairly simple and inexpensive controller, put out by Bachmann, called the EZ DCC controller.

This controller will control ten locos, including one analog (DC) engine. While this system isn't sufficient for a basement empire, it works very well for small layouts where you're only runnning a few trains at a time anyway. The EZ DCC controller costs about $100 retail, but is easily available for half that, especially from some of the EBay model railroad stores.

Bachmann also markets the decoders for the locos. They are available for about $20 each, and come with either a standard NMRA 8 pin plug or pigtail ends for soldering the connections yourself.

Of course, if you want to spend more money, and you will, there are other manufacturers and systems available. There have been plenty of reviews, so I won't bother doing it here, but will mention that Lenz, MRC, and others all make good products.

Don't forget that moving to DCC brings you into the realm of onboard sound! That will be a topic for another entry.

Welcome to the wonder world of DCC, Bliss! I like my little B-mann unit. It is a good starter unit.

My Porter bash likes it, and so do I with the sounds. It really is a nice new dimension to the hobby.
