This doesn't make sense... You build 99.999999999999% reliable systems but only some made it to the 20+ year mark and are still working...??

Some have been in the field less time.  Given 'em a chance.  They'll get there.

I have an 18 year TIU that is still working perfectly, and through software updates, I  receive all operating features as newest TIU built today. it has never been serviced, and it's reliability is well... 100%.

You're a rarity.  Good for you.

Really??? so every time Ford came out with a new version of the F-150, they were really saying the old ones were bad and should be recalled??? Why didn't MTH "recall" the older TIU's to be repaired or destroyed?? How many different Hardware versions are there of the Postwar ZW, are you saying that every ZW before the type R were also terrible and should be recalled?

I didn't say that.  You got that from what I wrote.    Somehow.

Think of new h/w as a RECALL.

New an improved designs are coming out all of the time by everyone. Look at how many h/w releases there have been of railsounds and how many more there will be. That doesn't mean that all the older ones are "recalls". I mean even the latest  Legacy Mogul was a new h/w release of the older tmcc version made years ago..... What an improvement that was...

When Ford builds a new h/w version of the F-150, they don't "recall" the older ones. There is nothing wrong them, they just took an existing design and improved on it.

For me personally, I hope that Atlas continues to provide pure DCC for their 2 rail locomotives.  DCS in 2 rail is a compromise when using a DCC system.

It never entered my mind that they would. Man, I hope they don't drop DCC ... would be kind of a stab in the back to all their long time 2-rail customers ... having to buy a DCS system to run their engines going forward. I'm well invested in DCC components and knowledge ...from both O and HO.

I was kinda hoping their MTH Premier engines would be offered with a DCC option. Wishful thinking.

....Five TIU versions and dozens of software upgrades in 20 years - doesn't look like a reliable system to me (and I built reliable systems for a living).  Over on the DCS sub-forum you have a legitimate rocket scientist (PhD EE from NASA Jet Propulsion Laboratory) who's had to diagnose and fix a number of DCS issues.  Doesn't sound like a case of simple user error or reliability, does it?



So what did you say about the upgrades and the system?

Let me preface this by saying I am a huge MTH fan.

H1000, you are lucky. Back when I was a 3 Railer I pre-ordered the first gen DCS system. It cost $300 at the time. I also ordered the AIU. I forget how much that was. I had a small layout at the time and the system worked okay. Unfortunately, one day I had somewhat of a short. It must have been pulling about 7-9 amps (just guessing) and the circuit breaker never tripped on my transformer which was a postwar ZW. Well, that let the smoke out of the TIU. I guess it was my fault for not using a more modern transformer but I felt the TIU should have been designed with circuit protection from the get go. Looking back maybe the CB in the transformer was faulty. If it was I didn’t realize it was faulty so it may have just been bad luck that the TIU got fried. The original remote also broke and this was not my fault. The wire going to the antenna board broke. I tried to fix it but a couple of traces came off the circuit board. Years later I sold the set for $15 to fellow forum member who wanted to mount it on a display board for some kind of presentation. The remote still worked but only if tethered. I still got the AIU and it still works perfectly.

I did buy another DCS set years later when the added the USB port. I still have it and have used it sparingly over the years for both the occasional 3 rail train or a PS3 upgrade I did. Even after all of this I am still a huge MTH fan. Hey, no train company is perfect.

About 16 years ago I spent double what I spent on my first DCS system to buy the NCE DCC system (and eventually had to spend more money on a power supply—initially I used the same ZW) but it hasn’t been upgraded, hardware or software in all the years I have had it and it still works perfectly.

Since Atlas will be using PS3 it can be controlled by DCC as Matt mentioned. I am not sure about the diesel side but a lot of my MTH steam engines have the same exact whistle. I like the sounds but I hope that whoever does the sounds for PS3 in the future will continue to upgrade and create a higher variety of the whistles and horns.

I also hope that PS3 upgrade kits will continue to be produced. I haven’t seen anything mentioned about the upgrade kits.

Actually, since Proto3 includes DCC, you still have a DCC locomotive.

While this is mostly correct, there is more flexibility and functionality to assign CVs to a true DCC decoder and there are more options for controllers.  Proto-3 also intentionally limited some of the DCS functions to DCC users as a way to sell more DCS systems.  Just an opinion on my part.  I prefer open architecture systems over proprietary ones.

Well am I lucky or am I good?

I got my first REV G. TIU in 03 and I didn't just plop it on the layout right away. I did some studying on the internals and critical thinking about how my KW transformer could kill this thing.  Long before MTH issued a news flash about placing a fast blow fuse between the TIU and Transformer I decided to put a 7 Amp circuit breaker between my KW and TIU from the get go.  This old TIU has seen many shorts and derailments and while it is not on the main layout anymore it still sees regular use on one of the portable layouts.  The PSX-AC replaced the 7 amp circuit breaker for better protection as soon as I heard about it.

I'll fault MTH for lack documentation due to not putting the early model through some real world situations. But with proper Circuit & TVS protection, that TIU should last a very long time.
