Heritage Units

 For reasons still unknown to me, I have acquired yet another Norfolk Southern heritage unit. This one is a duplicate, sort of; an SD70Ace in Erie paint. This one, however, is a Kato where my other is made by Fox Valley Models. It was a good price, and I just couldn't resist the urge.

I haven't taken any pictures to show the comparisons, but the differences between the two brands are well known. The Kato has molded in details where the FVM has a bag of yet uninstalled detail parts, the Kato locomotive colors are a lot brighter than the FVM unit, (a comparison of pictures online suggests the FVM is closer to prototype) and the Kato is capable of the expected rocket ship-like top speed while the FVM had a more reasonable top speed from the factory. 

Other than the excessively high top speed, the Kato runs with the quietness and precision otherwise expected from the brand. Installing DCC allows for the top speed to be reduced to a more reasonable level, and it has been speed-matched on the Digitrax system to the others. 

I have decided that, given the troubles I had with obtaining parts for my FVM locomotive, the Kato will replace the FVM unit on the show circuit and the FVM model will go on display. I will likewise replace any other FVM locos that I can find Kato substitutes for, but I don't expect that will be any time soon.

The Trouble with Digitrax, Part 2

The used Digitrax DT402D that I ordered came in, and it works. Sometimes. When it wants to.

As long as it is connected, it works like a champ. When it is disconnected it acts like it is still connected, but if you make a control input the white LED on the front flashes, which is saying it couldn't communicate with the command station. Every once in a while, if the stars align and all is right, it works wirelessly. Those times, unfortunately, are few and far between.

I sent a tech request to Digitrax and their answer was to buy a brand-new UR-93. I resisted for a while, but finally bit the bullet and made the purchase.* Results? Same thing. It works when it wants to. Another tech request to Digitrax asking for a test-and-check on the DT402D was DENIED!!! because it's obsolete and Digitrax doesn't have parts for it any more.

So the upshot is I have an expensive tethered throttle. Two of them in fact, since the 400R needs an UR-91 for simplex operation that I don't have. Once upon a time I could have sent it in to be upgraded to a DT402D, but it, too, is obsolete and there are no parts for the upgrade. That one does work by IR though, so it's not a total loss. The 402D supposedly has IR capability, too, so I might be able to use it that way as well.

I had played around with the idea of going with Digitrax with my new layout since it is going to be bigger than the old one. I still might, but for the time being my Digitrax experience is not all it could be.

It's my own fault for buying used equipment. I was trying to go cheap and it bit me in the rear. I can either suck it up and buy a new DT602D (or UT6D) that is supported or I can stay with tethered throttles. That's the price of buying someone elses problems, I guess.

*I also bit the bullet and bought the LNWI, so I could go WiFi if I wanted to, I guess. That, at least, works fine.

Whyyyyyyyy?!?!?!?!?!

 Why do I do this to myself?

So for my new-to-me Kato locomotives that I finally got all put together*, I decided to go with the good old XL Systems sound decoder. Why? Because I decided for some reason I wanted sound, the XL Systems decoders are about as low priced as you can get for sound decoders, and since I picked a pair of custom painted shells they weren't going to match up with any other railroad, so it didn't really matter if they would run with anything else.

I have written about XL systems decoders before, but to recap, they are a horrible decoder with  fantastic packaging arrangements. They used to make MRC decoders (and maybe they still do, MRC only has 3 and they all look very similar to the XL systems decoders with the same numbers), and to date MRC/XL Systems decoders are the only functional decoders I have ever thrown away.

The fantastic packaging arrangement is the inclusion of the speakers on the board, so they are true drop-in decoders. The new Kato decoder (1960B) has a cubic speaker that really sounds good, but the round speakers on the plain 1960 board is more than acceptable. They come pre-programmed with different horns, bells and prime movers to choose from, but unfortunately they have not seen fit to publish a table that tells you what setting is for what sounds. But that's not what makes them horrible. What makes them horrible is their speed table programming.

At speed step 1 the sounds notch up but the locomotive does not run. Well, one of the decoders I ordered for the Katos was defective, so when I sent it back for repair I asked about it. It turns out that CV2 (start speed for you non-DCC folks) has to be programmed at an insanely high level. XL says to start at 100 (which is at or above where you would normally program CV5 for top speed in any other decoder) and go from there.

There is also a kick function in CV65 (this is supposed to spike the voltage to get the loco to move slowly) that doesn't seem to have any effect. They also do not creep like Katos are capable of. With a TCS decoder, for example, the Kato diesels will crawl at 0.1 scale MPH, but with the XL decoder the slowest I could get the loco to consistently move was about 5 scale MPH. 

Setting the start speed so high also makes setting the top speed impossible. Try as I might, I couldn't get CV5 to slow the top speed down below about 175 or so; with the TCS (or Digitrax, or NCE) decoder the speeds can be scaled down to more reasonable prototypical speeds (I normally program mine to 50 in the middle and 100 at the top so that they roughly correspond with throttle percentage settings). At CV5=255 the loco zips along at a scale 350 MPH, but even if CV5 is set to zero (normally this doesn't work, with any other decoder brand the minimum CV5 setting has to be above CV2) the loco still runs exceptionally fast.

So I now have two Kato sound equipped locomotives with custom paint that run exceptionally fast that I can run together at the train shows. They should work out well there because train show trains at actual prototypical speeds of 65 scale MPH bores the onlookers, they really do look way too slow on the large layouts.

*I actually swapped out one of the new chassis for one that I had because the trucks and tank were black on one and UP gray on the other. I put the Chicago & Northwestern shell on the black trucked frame and used the chassis from one of my Union Pacific dash 9's (which I have more than plenty of) for the second custom painted locomotive. I used the UP's non-sound decoder on the CNW loco so it will run with the rest of them and put the XL sound decoder in the ex-UP chassis with the custom painted shell. That way my custom locomotives match, and I have a really cool CNW locomotive.

These Are Not The Same

 Last month the train club had a display at New Bern for the Coastal Carolina Model Railroad Club's annual event. It's always a good show, and as always we had a great time there.

While I was there I happened to find a pair of Kato locomotives for a very attractive price. Attractive meaning $25 each for one C44-9W that appears to have started life as an undecorated model and one AC4400CW that appeared to have started life as a Canadian Pacific unit. 

Both of these units had been rather horribly redecorated with red paint and some sort of turtle decals, but a bit of work with some IPA and a short-bristled brush cleared that away in short order. The dash-9 unit was also missing a sill piece, creating a space between the tank and the body.

These sill pieces were apparently made of unobtainium, because I was not able to find them on the Kato website. In fact, the handrail sets for the C44-9W listed on the Kato website looked nothing like the pieces that I had installed on this locomotive.

At first I went to the mailing lists and there were some folks that had complete body shells that they were willing to part with. I made some purchases and found that, although they fit the mechanisms, they were different in that they not only did not have that sill piece, they didn't even have provisions for it.

I was finally able to find it as a part of the handrail set for the AC4400CW, so all was well. However, it did spark my curiosity, so I looked at the other Kato dash-9's that I have in my collection, and as far as I have been able to tell there was a change in the model. 

Which one came first? I don't know, but the shells that came with the $25 units were the type that had a sill plate and the ditch lights are mounted on top of the porch, as on the BNSF locomotive pictured above. In the other model the ditch lights are below the porch and there is no sill plate, as on the UP locomotive. The gap in the second version is filled by the fuel tank, in the first version the sill sits behind the protrusions in the fuel tank.

 

Note the tank protrusions and the sill plate on the BNSF model. In my opinion this is the better looking version of the two. Unfortunately I didn't notice the difference in the ditch lights until after I had taken these pictures, so I haven't illustrated that difference. The dash-9 shell that came with the $25 mechanism is this type.

Note the lack of sill plate on the UP locomotive and the extension on the top of the fuel tank. The bottom of the walkway has protrusions that fill the gaps between the loco shell and the trucks, and the gap between the tank and body shell is filled with the tank extension. All the dash-9 shells that I purchased separately are this type.

Also notice the protrusions on the front and back bottoms of the mechanisms. The ones on the UP version are longer than the BNSF model. They are also thicker at the extreme ends, and they are stepped, where on the BNSF model they are not. The two $25 mechanisms are identical, and are the same as the BNSF version.

In all other aspects the mechanisms are the same except for this bit of casting in the front and rear. The part numbers molded in the side frames are the same as well, even though those castings have that minor difference. Note also that this is the exact same mechanism as is found on the AC4400CW and also on the Kato ES44AC (those models have the non-stepped versions of the chassis).

The upshot is that now I have two fully functional Kato locomotives for around $30 each (I only needed one sill plate and it was found in that $6 handrail set mentioned earlier) including parts and the paint for the undecorated unit. They are in matching red livery, but they are now decal-less. I could just order some Canadian Pacific decals, but I think I will have to come up with something special for them.

I also have some body shells that need the extended gas tanks. Fortunately Kato has them on their website, so I have ordered a few. One of the shells was the Chicago and Northwestern 8727 in Operation Lifesaver paint, so that may find its way on one of the two mechanisms instead of a red shell.

Either way, my diesel fleet continues to grow.

Something New

 I am playing around with airbrushing.

And by playing, I mean that in the most literal sense. I am using a really cheap Testors external mix airbrush kit that I picked up really cheap several years ago from somewhere I don't even remember, it's been that long. I have been meaning to give it a try for a while yet, and so I decided that now is the time.

The impetus for the project was a complete non-running Atlas/Kato RS3 frame that I got on the auction site for parts. When it arrived, just out of curiosity, I pulled the motor and tested it. It was completely dead, but when I pulled the brush caps off of it I found a broken brush. I installed new brushes and it ran.

I reinstalled the motor and found the wheels to be so gunked up that it wouldn't pick up power, so of course I had to clean them thoroughly and apply some Conduct A Lube on the axles and truck contacts. After that I had a perfectly running mechanism.

I have a couple of RS3 bodies, complete with handrails and Micro Trains coupler conversion kits, that had been repainted rather badly, but some time in the ultrasonic took the paint right off. I wanted a better paint job than brushing would produce, so out came the airbrush kit.

So far, I have to say I'm happy with the results. I only have the light color (very light gray/green) base coat on it. I need to mask it off and put on the second color, which will be much darker (Brunswick green), but I don't have the proper size of masking tape. It's on order and should be here tomorrow. Gotta love Amazon next-day delivery.

I'm hoping for a final result of a Brunswick green locomotive with a pale gray/green stripe running the length of the body side. If it turns out as good as I hope, I will also try putting some diagonal yellow or gray/green lines on the front and rear. I will then print out some black decals for the light color stripe to complete the body shell. 

If it works out, this will give me the first locomotives for the standard-gauge portion of the Path Valley Railroad. And, if they end up looking the way I want, I have some GP7 shells to paint in the same scheme.

I also have a bit more expensive (but still relatively cheap) Harbor Freight internal mix airbrush kit that I haven't unpacked yet. The internal mix is supposed to produce a much finer coat than the external, so that is probably a better way to go anyway.

From everything I have read about it, and from the review videos I have seen, the Harbor Freight kit is actually not bad (although I think a compressor with a tank would give more consistent results). It might be time to finally break it out.

And if I like it, there is a tank kit for it on Amazon.

Apropos of nothing I suppose, ten years ago yesterday my lovely missus agreed to go out with me for the first time, thus sealing her fate.

UPDATE: And the results are:

Appearance-wise, I think it looks very Erie-ish although that wasn't really my goal. Otherwise I really like the way it turned out. Now I have to find my clear decal paper and print some decals.

The Trouble with Digitrax

A couple of weeks ago the club had a show. The setup went fine and everything was looking good... until it came time to run some trains. Unfortunately something had happened with the command station setup (Digitrax booster connected to a laptop with Java Model Railroad Interface connected to a wireless modem) and we weren't able to connect with our cell phones. This made me very sad since that meant I couldn't run trains. However, those club members who had radio throttles were able to connect, via a Digitrax UR93 duplex-only transceiver which is connected to the booster's LocoNet, and run trains with no problems.

One of the club members had an extra throttle that he graciously loaned to me, so I was also able to run some trains, and that got me to thinking that I needed options. So onto the E-pray I went where I found an inexpensive used Digitrax DT400R, which looked like the DT402 throttle that is in my new-to-me Digitrax Empire Builder set (those who know Digitrax are shaking their heads right now). I don't have a receiver for it yet, but I was able to operate it tethered and with the IR, and it works great.

Unfortunately though, it looks like I screwed up with that purchase (those who know Digitrax are nodding their heads right now) because the 400R can't do duplex operations, which is what my club's UR93's are, and I compounded that error by ordering a Digitrax UR92 interface panel for use on my Empire Builder set, which is also duplex-only. Bottom line, the throttle I have won't work with the club's DCC setups, and the interface panel I ordered won't work with the throttle I have, either.

That means I need to order a DT402D if I want to stay vintage and get the proper type radio throttle to work with my club, and either sell the 400R or get a simplex UR91 panel to go with it. I've put an offer in for a 402D since that's what I really need, so we will see what happens.*

To say I'm a wee bit disappointed with my Digitrax experience so far is overstating things a bit, but not by much. It's my own fault, though, so I can't really blame Digitrax as much as I want to.

The problem is that Digitrax has so many different versions of everything, and not everything works with everything else (especially the older stuff), and Digitrax has a bad habit of making their newer stuff not backwards-compatible, so you really have to be careful when buying Digitrax equipment (and plan on buying a bunch of new stuff when you upgrade, apparently). Word to the wise, people, do your homework and refer to this guide from Digitrax that I really wish I had seen a lot earlier than I did.

To go radio with the NCE requires an RB02 radio base station and either an NCE radio throttle or a modification to my current PowerCab to add a radio transceiver to it. I have no plans to do so because it was a whole lot easier (and cheaper!) to go wireless by installing a WiFiTrax WFD-31 panel and use the old cell phone throttle. That doesn't help me out with my desire to go radio in case of issues with the club setup though. 

For what it's worth, going the cell phone route with Digitrax only requires the purchase of a Loco Net WiFi Interface (LNWI) module which hooks up to your existing LocoNet, but since my Digitrax is not currently part of a permanent setup I don't need it, and it's more than I want to deal with right now. (The club doesn't use them because of their limited connectivity; four devices per LNWI and eight maximum LNWI modules per setup, and we have more than 32 devices wanting to connect on some of our big NTRAK layouts.)

*Simplex means the radio traffic only goes one way (between the throttle and transceiver) at a time, duplex means the radio traffic can go both ways at the same time.

Blunami! Pt II

 In a couple of previous posts I told the tale of the new Soundtraxx Blunami decoders and showed how to install one in an N scale Bachmann 4-8-4 Northern locomotive. I believe the N scale Bachmann J class also has a large enough tender to install a Blunami, so I might try that since I have one of the older versions (but not white-box older; it's one of the 2006 and up releases) that I had to put my own decoder in. I equipped that one with a Soundtraxx TSU-1100 decoder, so there should be enough room... maybe...

But I digress.

In those posts I touched upon the operation of the locos using both the Blunami app and the DCC system, and I was also able to test it using my cell phone as a throttle on the club's DCC system. I have yet to try operating the loco(s) on straight DC, perhaps I will one day but since you can control the loco through the cell phone app on DC it's not really important. The only quibble I had with the Blunami app was there wasn't any way to consist locomotives, not on the Android app at least. 

Well, I'm happy to say that there has been an update to the Android app, and now it is completely possible to consist your Blunami equipped locos on the Blunami Android app. You can't consist non-Blunami locomotives, of course, but I was able to consist both of my Blunami equipped Northerns and run them around my test track using my new-to-me Digitrax Empire Builder DCC set that some sweet lady got me for Christmas. 

And even though I programmed these locos on my NCE set, as I had done with my previous locos, they ran perfectly together... probably because they were identical locomotives (I had a third with a newer type can motor that I matched to the Blunami that was in my installation post; the older motored version got a Digitrax equipped tender) with identical decoders. It's probably a fair bet they won't run with differently branded locos and differently branded decoders until I match them on the Digitrax set, but that's an issue for another day... maybe.
