Howdy,

 

I have a few quick questions for ya and I don't mind a long winded answer, in fact it is encouraged:

Will a TMCC controlled steam loco run at the same speed in a consist as a TMCC diesel? 

I don't have a lot of TMCC operating experience, all of my Lionel stuff is Legacy based.  I have one TMCC diesel and it wouldn't run in a consist with my legacy diesels.  I didn't try changing the control format in the remote, I just figured that was the way it is  I have a lot of step grades on my layout and a single steam loco won't pull more than a dozen cars up the hills so, I convert a small diesel loco into a powered box car and run it as a consist.  I am considering an older Lionel TMCC PRR T-1 to pull my GGD fleet of modernism cars.  I have a TMCC RS-11 that would get the "box car treatment" to help pull it up the hills.

 

Thanks!

From my experience, and what others have told me, TMCC or Legacy steam and diesels do not mate up in a lash-up. The gearing is totally different. I played around with a Legacy UP E7 and my Legacy 4-8-4. Never got them to sync. 

What I do when building a lash-up, I place the engines on the track about 1 to 2 feet apart. Once the lash-up is made, I then run them to insure that both are in sync, and that one does not move faster or slower than the other. 

If they all run in sync, then I know I can couple them up and run 'em.

First off, if you have similar engines, there's a couple of rules.

You MUST run the consist in TMCC mode as it can't be configured with a Legacy as the lead.

You'll likely have to turn cruise off of at least the TMCC engine, that gives it a lot of "slop" to deal with speed differences.

Although GRJ's answer is not "Long-winded", it answers your question in a Nut Shell.  GRJ always comes from a reference of Vast Knowledge of our Hobby.
