TMCC/DCS Lash up

According to Barry's DCS Companion, you can run a TMCC Lash-up with the DCS remote.  I haven't tried it, but it looks fairly simple.

This same question appeared both here and in the TMCC/Legacy forum submitted by different folks.  I responded that it should work and, I believe that Barry mentioned it in his book, but I have never tried it.  At just about the same time GRJ responded in pretty much the same way.

Today I had nothing to do so I tried it out.  I used the Premier app on my iPad.  First, make sure that both locomotives are present in the app and that both are active.  At the top click Choose or add and engine .  At the bottom under ADD click on Build Lash Up.   You have three choices, DCS, TMCC or Legacy.  If you are pairing a TMCC and a LEGACY select TMCC.   Mine were 2 Legacy engines.  Click on Build Legacy Lash Up.  Give your lash up a name and select the TIU by just touching the appropriate one.  Now click Next at the top right.  Now select one of the engines from the list and select whether it will be the Head, Middle or Tail engine.  Now select which direction it is running.  Repeat the process for the next engine and any additional engines.  Finally, click Done.  Both locomotives should start and the horn/whistle of the lead engine will blow once.  You're done.

I left the locomotives uncoupled just to be sure everything was working correctly.

I hope this helps.

So I got this right, I have one TMCC and one Legacy. Having both engines already on my engine list, I should select Lash up for TMCC. 

Yes.  As I did, don't couple them together until you are sure that they are doing what you want.  The great hand from the sky can couple them, if everything is okay.

Thanks Dan.

Here is my note to Dean Brasseur at Lionel Customer Service, to better explain the problem as I followed the above suggested tips with no success.

Hi Dean,

ALCOSRUULE, if they work individually, I really don’t understand why they won’t cooperate as a lash up.  You should have only had a single blast from the horn, not several.  There is something that it doesn’t like.  Maybe Dean has a good answer for you.  In the meantime, were you able to create a lash up using you Legacy remote?

Dan, I agree. I’ve not heard back from Dean as yet.  I do not have a Legacy system/remote, just using a DCS /TMCC set-up.

I’ve had instances where I’ve gotten 4,5,6 horn blasts which is really odd. Sometimes, both engines are in sync and repeat the same sequence, other times not.

As an aside, I pre-ordered both engines, upon receiving them, neither engine would log in to the DCS remote. Both had to be returned to Lionel where they flashed each engine and tested them before returning. Upon receiving them, they both logged in with no problem. But, the problem remains that they will not sync up as a lash-up, yet.

Thanks Dan and John, I won’t get another chance to mess with them until this weekend. I’ll try what you suggested. If things get to troublesome with the DCS WiFi, I’ll just run them off of my Cab 1.

It will work.  If you are using CAB1, use the TMCC lash up, even if both locomotives are Legacy.  Let us know how you make out.

DANR, so far things worked as describe by you.
