When running multiple units together aka L--h- up, which is better or preferred? Odyssey on or off?

 

I have a #4979 UP SD-70-the flag one and #4980 UP SD-70-the one from the overland set and want to run them together as a TR. They are both TMCC engines running on a flat layout surface and using Legacy to control them. Seems to me that both almost start out at the same speed with odyssey on but do run together with it turned off.

Which is better to do? Should I set the momentum higher on each individual unit, then put them together? You would think that since these engines are really alike, they would operate together but Lionel's first odyssey system is subpar in comparison to MTH's system.

These engines are quite similar and I will try to operate them at 1=2 inches apart and observe them. Yes, Legacy odyssey 2 engines do run well together. It is the TMCC odyssey engines that do not always perform together. You would figure that 2 Union Pacific SD-70's that were made in the same year will have similar odyssey versions and would run  together well. I have tried setting the momentum to a higher level to help them start out at the same speed.

Tried running these similar engines about an inch apart with odyssey on and one starts at slightly faster so their distance between them differs about 6 feet down the track. In other words, it is a no go as one of the engines when coupled together, the motor gets a little hot on the rooftop. When running it by itself, there is no extra heat coming from it.

Like I said in past posts about odyssey, it is a crapshoot to "MU" Lionel engines together. Really wanted to "MU" these 2 Union Pacific SD-70 engines together but as usual, odyssey is subpar when compared to other speed control systems. Lionel might have corrected it with Legacy or with Vision but their first version of odyssey is disappointing.

Ted,

 

  I ordered two NS SD-60's  from the 2002 catalog. I was wanting to "MU" them. It will never happen as these units don't have a Odyssey On & Off switch and fight each other. 

If a motor driver or motor encoder ever goes bad in one or the other, they will both be upgraded to a ERR Cruise "M". Them I will "MU" them. I will say they each are excellent runners using a Cab2.
