Always test the system when there's an issue like this. The layout might be a problem. So just connect it to a short piece of track with nothing else connected. 

Just because it says it's been updated, doesn't mean much to me. What version is the TIU?

#1 is the TIU light on? sounds like it is if the remote is finding the TIU OK, if not tether it.

#2 is the track powered? If no power is getting to the track nothing will work.

#3 it's used. So yes, do a reset of both items to clear them.

#4 see exactly which DCS version is in each piece. They both should say DCS 6.1 and both need to match DCS versions.

Press read once all this is ready and report exactly what you get. If it says "no DCS active engines" or similar statement, like I believe you're seeing, and you have power going thru to the track, the TIU may need testing for signal. Does an engine stay dark and silent when power is applied? or do engines fire right up?

If they are silent it might be because they're not getting power? Reading your statement above still leaves me with many questions to guess at what's happening.

You might consider telling us EXACTLY what model locomotives you have.

Thank you guys. I am totally new at Command Control stuff. Please be patient with me. I have a couple of TMCC engines and I have them working fine with the Lionel version. I got this because I wanted to run both with a single remote.

ANSWERS BELOW:

 I have this on a test track. I have tried 3 engines. 1)Subway 30-4122-1, 2) Subway 30-2211-1, 3) 2380 Southern Pacific (model unknown)

Always test the system when there's an issue like this. The layout might be a problem. So just connect it to a short piece of track with nothing else connected. I have not put this on the layout yet. It is on a test track.

Just because it says it's been updated, doesn't mean much to me. What version is the TIU? Rev 13

#1 is the TIU light on? YES sounds like it is if the remote is finding the TIU OK, if not tether it. What cable do I need for that? Looks like a RJ11 phone jack, but it is not.

#2 is the track powered? YES If no power is getting to the track nothing will work.

#3 it's used. So yes, do a reset of both items to clear them. How do I reset them? I cannot reset the engine because it doesn’t see it.

#4 see exactly which DCS version is in each piece. They both should say DCS 6.1 and both need to match DCS versions. Where do I find the version number?

Press read once all this is ready and report exactly what you get. If it says "no DCS active engines" or similar statement, like I believe you're seeing, and you have power going thru to the track, the TIU may need testing for signal. You are right, it says “no engine to add”. How do I test the signal? Does an engine stay dark and silent when power is applied? or do engines fire right up? The engine lights up. That’s it. No sound except for the Southern Pacific which does fire up.

If they are silent it might be because they're not getting power? Reading your statement above still leaves me with many questions to guess at what's happening.

All your engines sound very old? Are the batteries charged?

Put them on powered track and start them up. Kill the power. How long do they keep making sounds?

The tether cord is a 4 wire handset cord from phones.

Reset the TIU and the remote.

Start with the engines, connect just a transformer and verify they run in conventional mode.

Next, let's do a simple setup.

• Connect the transformer to the TIU FIXED #1 inputs.
• Connect the test track to the TIU FIXED #1 outputs, red to center rail.
• Place one of the engines you tested in conventional mode on the track.
• Apply power.

Do you hear a click as the relay in the engine energizes?

Does the engine start up in conventional mode with sound, etc., or does it remain silent?

OK Guys: I tested my 3 engines. One lights up but will not move and no sounds. One lights up and has sound, the third is actual a Lionel and I will address that after the first two. Right now, I am guessing there is something totally wrong with the one that just sits there Yes? It is the Subway 30-2211-1 (R-21 Subway). The one that works and emits sound is very similar (NY Yankees 30-2211-1). There is no click.

1-2-3 you're out! 

Please understand, we have no way of knowing what's really happening. We get a brief description and then usually have to guess at where to go to fix things.

So!,... forget the DCS system for right now. You have nothing to run with it yet.

The Lionel will only run in command, if it has it?, if you connect the TIU to the TMCC base. Otherwise it maybe conventional only (just a transformer).

The one that does nothing, needs something fixed first.

 So the one that has sounds, probably has a dead battery. We don't know with what you have told us so far.

What power are you using to run it? Do you know how to run it? 

If the battery is dead don't do anything until you replace it!

Turn power down and back up to get out of neutral. There is a track to it as you can't have the power too high at first to shift out.

You really need to get the basics going. You need to read the instructions on operation of it on the MTH website.

That subway is from 2001! The battery should be replaced and the new one fully charged first.

Here's your instruction manual:

Your stuck in a position to not know if both trains and DCS are issues.  I would take to a LHS to have trains tested on known working system. Then with known working train you could test DCS system on a small test track as Joe mentioned.  G

Thank you. These days, impossible to find anything open. Frustrating but you are right, I am stuck with two unknown engines.
