Double heading TMCC with ERR

Ralph,

I have not done double-heading with the different scenarios you mentioned.  However, I have double-headed a pair of Williams PRR K4s engines equipped with TMCC (TrainAmerica installation with EOB).  I've also used these as a lash-up with 1 locomotive pulling at the front and 1 in the rear pushing.  Worked great and looked pretty good doing it, too.

Run the two engines in lashup mode but separated by several inches. If they stay fairly close together over the speed range you plan to run them, then they should work doubleheaded/MUed.

Turning off a cruise may help smooth out differences. 

I run several doubleheaded/MU consists in TMCC lashup mode, but Like George’s they are made up of the same engine with the same electronics.

Running two dissimilar steam engines doubleheaded with each engine controlled separately might be interesting. I’d practice that first with the engines not connected.

Here is a consist of a Lionel Legacy GP30, Atlas O Trainman U23B with TMCC, MTH RS27 converted to ERR TMCC, Williams F3 converted to ERR TMCC and a        K-Line GP38 upgraded with ERR Cruise-M.  They all seem to play well together.  The key is to experiment and compare engine speeds individually before building the consist.

The ERR back-EMF cruise is a bit more forgiving than the Lionel Odyssey or MTH DCS cruise, there's some "slip" if they're not quite matched.  In addition, the ERR cruise has the "nudge" feature to match speeds.

Good advice from all.  From my experience it is best to turn off the cruise. And I agree that ERR is most forgiving .  Got'a love the  nudge feature!  

Hey Tom - Your locomotives do 'play well' together. LOL  It would seem that ERR would pair up very well with Legacy since both can start out very slowly. And it is this that makes me want to double head an ERR locomotive with a DCS locomotive for the same reason.  Just the novelty of it i guess.
