Update: After consulting with TCS, I no longer recommend the TCS Z2 decoder for this installation. Sadly, the TCS M1 is too large for this installation, and so I have selected a Lenz Silver Mini to replace the Z2. Previously, I showed how to disassemble the tamper down to the point where we can proceed with decoder installation. Let’s move forward with the decoder installation itself. 
 The Duomatic itself. Stop. (Collaborate and listen.) You just bought one of these fancy Lemke ballast tampers, and you are considering converting it to DCC. You can read a little German, maybe, or at least you can work from photos; or you found another guide on the web. It doesn’t look so hard. Don’t believe everything you read. Just an update on this project. I managed three more cars in one evening, for a total of four out of seven. It’s tedious going, but I’ve got the hang of it now. What’s slowing me down is cleaning the trucks: They’re filthy! Spent the evening with a bowl of rubbing alcohol and a [...]  Kato 10-173 651系 'Super Hitachi' So, you have just purchaed Kato 10-173 651系 (651-series) “Super Hitachi”, and want to know how to convert it to DCC. I’ve just begun this process myself; here is part one (of many!) of my report. The 651系 is factory-fitted with interior lighting, a nice touch. But, being bulbs, those lights have to go. For one, they draw a ton of current—55mA/bulb @ 9 bulbs = almost half an ampere!—which limits the number of trains that my Digitrax Zephyr can drive simultaneously from two to one. For another, bulbs get hot when powered by AC, and DCC is AC. Some people have reported that Kato’s bulb-based interior lights cause meltdowns when run on DCC. I don’t have a link, because I think this claim is largely apocryphal, but Kato nevertheless cautions against using their bulb kits with DCC. Or at least they did until they discontinued those sets. Anyway, Kato’s LED interior lighting kits aren’t compatible with the 651系. You’ll see why below. This means we’re going to have to improvise something new if we want to run out 651系 on DCC. The EF81 done, I’ve been trying to decide what DCC project to tackle next. I’ve settled on my Kato 651系 for several reasons. First, the set is being re-released next month, which means a new wave(let) of interest. It also means a new wave of spare parts if I mess up. Too, the pre-fitted [...]  It lives! Tomix EF81 with working DCC provided by a TCS CN-GP. [Update 7 July 2010: The decoder failed by February. TCS advised that the CN-GP is a very delicate decoder; consequently, I cannot recommend this installation method. Currently looking for a new method of installation. Watch for future posts.] Read Part 1. It’s done. Well, almost. [Update 10 Jan 2010: Yep, it's done.] Anyway, it works, and that’s what counts. Here then I recount the two hours I spent last night making it work, and the year of effort that culminated in those two glorious hours. (Yes, it takes me about one year to install one decoder. No, I’m not that slow: it’s just a function of how much free time I have, and how I choose to spend it.) This has been an awful week, for reasons I won’t dwell on. But as is often the case, I attempted to wrest control over my life by relaxing with my trains this weekend. And, as is increasingly the case, this attempt led me only to frustration. Before me are four models that have issues. [...] I’ve lost track of how many decoders have been fried in the name of getting my Tomix EF81 converted to DCC. I’m not at all sure what happened this time; I was very thorough in checking for shorts before I put it on the tracks. And, sure enough, when I power it up, it [...] TCS has just announced the K0D8 decoder for Kato E8A/B, F7A/B and P42 Genesis locos; it should be a drop-in replacement for nearly every Japanese outline electric locomotive Kato has produced in the last several years. I have updated the listings accordingly, and will update them when TCS releases more information |
