Is Atlas PS3 and MTH PS3 one-in-the-same??

Yes, they directly licensed MTH PS3 and MTH produces the control boards for Atlas.

"Do I need to assign a TMCC address to the Atlas in order to use it with MTH?"

No, again, PS3 is PS3. TMCC is only TMCC engines. Atlas made both but completely different electronics.

Thanks Vernon, that's what I surmised. Just seems odd that my MTH DCS won't "find new engine" when I power up the tracks.

Unless Atlas doesn't like iPads.....dunno.

How many switches did Atlas stick in there?…is there a 3/2 switch?…..you’ve posted in traditional, so 3 rail I presume, …be sure it’s set to 3 if so equipped …..let’s see a pic of your engine’s switch bank if you’re unsure…

My understanding is they're supposed to be the same. One thing that happened to me with a PS3 locomotive was that even though it was a hi-rail locomotive, it had the switch in the DCC position. I'd manually set it to DCC, then back to DCS. I'm not sure if the 44-tonner had a 2-rail option, but if it does, check that switch too.

I intend this to be 3-rail. There is no 2/3 switch. Only a volume pot and the DCC/DCS switch.

The (scant) instructions said for 2-rail , remove the rollers and move the switch to DCC.

Could the DCC/DCS switch be wired wrong? Try it on DCC.

If you're trying to find this with the DCS system, regardless of 2-rail or 3-rail, the switch MUST be in DCS!  If the switch happens to be defective, the default open is DCC, so maybe it's just bad/flaky switch.

Let's go with the flakey switch. I moved it DCC and powered it. It lite right off as though it would in conventional. I did not try to move it. I powered down and put the switch back in DCS and then it could be "found" using Add New Engine, as they usually do.

Summed up....it's now working!!! I have other Atlas PS3 locos on order for late 2022 delivery. Let's see how that goes!  

Thanks to everyone who chimed in here!

If the switch continues to be a problem, you can just jumper the two wires on it and it'll always be in DCS mode.

I moved this to the Atlas forum BECAUSE it is discussing an Atlas product.  Come on...this was obviously NOT about a traditionally sized train.  Guys...help us out by reporting these instead of responding in a thread and not alerting us that it is in the wrong category.  Searching is already tough enough but it gets much harder if the topic is placed in a forum that most would not think to search.

OK and the real technical discussion was PS3.

So does this go under Atlas, or does it go under MTH control system for PS3?

Is there a new category for PS3 under Atlas?

This was directed to me by the moderator tonight.  Since the topic is about an ATLAS product, then it should have been in the Atlas forum.  If the discussion involved discussion / questions about PS3 only, then placement in the MTH category would have been fine but this was a question about a specific Atlas product and the system that it uses.

Thanks for the amplified guidance.

In conversations with the Atlas folks, former MTH products they offer are exactly as MTH made them, no changes or revisions.
