Farewell to the Mighty Z

DCS50 Zephyr
This Digitrax DCS50 Zephyr has served me faithfully for more than a decade on two layouts

***Update Oct 22, 2022. The Zephyr is not yet gone, and I may just keep it. I’ve figured out that I can still use it to turn track power on and off, even in booster mode, and the odd scrolling LEDs that come with placing the unit in booster mode aren’t quite as annoying as I remember. It also seems kinda handy to be able to quickly punch in a loco address and run a locomotive with the Z when doing things like speed matching… so, even though it’s no longer my command station, it may just stay right there on the fascia.***

This past Wednesday marked a milestone on the layout–it was the last time my layout was controlled by my venerable and dependable Digitrax DCS50 Zephyr! The “Z” is known as an entry level system, but it’s historically been my favorite to use as a command station because it’s very easy to operate and made a great stationary controller for creating consists and programming decoders. On both my previous layout and this one, I used a specially made box created just to mount the Z on the fascia in a convenient spot. The Zephyr’s 2.5A were never enough to power my entire layout, so there’s been an old DCS100 command station/booster serving as the booster behind the scenes, but the Z has always been the command station, and I’ve always had fewer than 10 locomotives on the layout at once, so the “slot” limitation has never been an issue.

Two things have happened recently that precipitated a change away from the Zephyr. First, thanks to my adoption of sound decoders and their braking features in all locomotives, I switched from “universal consisting” (command-station consisting) to “advanced consisting” (decoder consisting) to be able to control functions in all decoders simultaneously, so I can do all my consisting in JMRI instead of in the command station. While this method takes up even fewer slots in a command station, it also eliminated the need to create consists using the Z, one of its greatest strengths. Secondly, my old DCS100 has been getting more and more finicky over the years, often being disagreeable and “forgetting” its a booster. This never created any operational problems, but it was a constant source of angry beeps from the DCS100. I had a few options. First, I could just revert to using the DCS100 and upgrading to a newer advanced throttle (it came with an ancient DT100), but the DCS100 was starting to show its age. I also played around with a new generation Zephyr Express (DCS52), but I found the screen and buttons too bright (I want to run night operations), and the DCS100 REALLY didn’t appreciate working with the new Z, and it was more difficult than I’d hoped to get them to play nice together. Ultimately, I decided that the best answer would be to just upgrade the whole command station/booster combo.

I ended up going with the Digitrax Evolution Express (EVOX) which includes a 5A DCS210+ booster, 100-slot command station, a USB interface, and an a DT602 advanced throttle to control everything. It’s plenty of power for the layout, and I’ll never need the additional capacity of the top end command station. I splurged on the duplex radio version because I figured it would be worth it to upgrade my 2-way radio system to the newest receiver (UR93), and I wanted to preserve the ability to use the DT602 wirelessly, even if right now it’s serving as a glorified power button. Installation of the new system was easy, and everything works like a champ! I’ve also now got a spare command station, spare 5A power supply, and spare duplex radio receiver if I need them. I’ve also got a backup method for connecting my Digitrax to JMRI, even though for now I’m sticking with my old PR3 rather than using the DCS210+ USB port… it’s working well, don’t mess with it!

Anyway, I didn’t want to let this moment pass without giving a big shout-out and thanks to my Zephyr for the many years of faithful service on the layout. I don’t know many who use a Z as the command station for a good-sized, serious layout, so I was happy to be a long-time advocate! I already miss one simple thing: the ability to just push a button on the Z to turn the track power on and off. I’ll say farewell, though I have no plans to actually get rid of my Z any time soon… maybe I need a stand-alone programming station… hmm…

One final thing. If you’re trying to turn the track power on or off using a DT602 super throttle, and you can’t get the soft keys for track power to stay there long enough for you to actually push them, you need to press on the LEFT side of the power button and not in the middle. Might just save you a help-desk ticket with Digitrax… not that this happened to me.
