This is something that also hasbearing for many of you folks, so I’ll revisit it here. When I wastroubleshooting the first system with an old HP oscilloscope,I discovered that my US Hobbies-vintage steam, scratchbuiltstuff, and lit passenger cars created some very high-amplitudeshort-duration amperage spikes that spelled eventual doom forthe then-current crop of decoders. The problem was in thepickup paths. Every little arc over oiled journals, truck bolsters,and iron wheels would cause one of these spikes.I’m still not convinced (yet) that the newer crop of decodershas addressed this robustness issue, or if they ever can.There is salvation for me, however, in two approaches. Sincemy mainline is wired and blocked for conventional cabcontrol, I simply wired them to be switchable between theoriginal Controlmaster 20 conventional throttles and DCC.Each set of track leads is dropped to the center taps of apretty beefy double-pole rotary switch. Then, the track leadsfrom the Power Station 8 booster are wired into the first pairof contacts (label that position “DCC”). The track leads fromthe conventional throttles are wired into the second set ofcontacts (label that position “CAB”). Pay very close attentionto matching polarity as you wire each rotary. I used rotaryswitches because I still have to test products equipped withsome of the proprietary control systems, each wired intosubsequent pairs of contacts. For your purposes, though,a healthy double-pole double-throw toggle switch will getyou there if you’re sticking with the two options. After finishingthis little exercise, I could run one of mymyriad old sleds (and I have a lot of ‘em!) withimpunity on conventional cab-control on onemainline track, a pair of DCC-equipped P&D F2s on the other,and switch the industrial areas with our boxcab. Manipulatea few switches, and any <strong>com</strong>bination is possible. If you pullthis stunt, though, make sure that the gaps between sectionsof railroad are mechanically re-enforced with insulated joiners,epoxy fill, or styrene to avoid that expensive acrid odor resultingfrom crossed systems.The second approach, of course, is to do the work on thosepieces of rolling stock and motive power to minimize the numberof mechanical connections (especially oily ones) in theelectrical path, such as adding phosphor-bronze pickups toend-run the through-the-journals/ through-the kingpins path ofconventional practice. Anything earmarked for DCC operationwill eventually cross the workbench for this treatment at thesame time the decoders go in.Some Conclusions, and the Future:It is nice to see that MRC has done quite a bit of work in adirection that benefits folks like me. Rather than give the geeksamong us new nifty features, MRC is making what is probablythe current top-end norm in capabilities much more friendlyfor the rest of us to use and enjoy.By the way, I’m not saying that this is the only system outthere. Check them all out as you design your system for yourtastes. I will say that Frank and MRC were the first to have the,uh… confidence (…yeah, “confidence” is the word I’m lookingfor here) to take on Scace the Ludite with their product line,and the price point is worth paying attention to. As anotherthing I consider, I’ll also mention that MRC has always supportedmy gear over the years. I’ve had to send in a coupleControlmasters that I roached (not a warranty issue, but myown stupidity), for example, and they cheerfully fixed me upwith a very quick turn-around time. They’ve been aroundfor many years, and their support of their product line, in myexperiences, has always been excellent.With the Prodigy system, I have to appreciate the effort incatching “user-friendly” up to the technology. They got megood, and so did Peterson.Send $2 forPrice Info andCatalogR•BISHOPP.O.
