Multiple Unit Consists with Pullmor Motors: Best way?

Hi  Bill,

 

 If these are ERR upgraded make sure both units are set for 32 speed steps or 100 speeds steps. Stall is not available in 100 step mode.

Looks like the B unit already have Lionel TMCC Bill, so I can't imagine they went with the ERR AC Commander.  I don't know what that number for the A unit is, doesn't come up with anything for me.

 

Hi Bill and John, thanks. The B may have ERR, because the original LCRU in it would not take a sound addition. I will check with my invoice for sound upgrade. I suspect you did add ERR to it.

 

John: number on instruction sheet for A unit is 71-8130-250. A unit I am sure does not have ERR.

 

It would make sense if A was in 32 and B was in 100, that would explain why A starts so much more quickly. Will investigate tonight.

 

 

The "hidden" information was the ERR upgrade for the B-unit.

 

It's easy to program the B in 32 step mode if it has the ERR.

Problem solved!  As soon as I got home from work, I went down and set B unit for 32 speed steps, then reset stall speed. Now both units respond and start virtually simultaneously.  Thank you both very much! 

 

How about that! Bill got his problem solved and we never used the dreaded lashup word!

 

My mission is slowly succeeding. Congratulations to you all. 

No question about it, this forum has some great folks.  Now, Boxcar Bill, I have this coach I've been working on, you wouldn't happen to have O-gauge carrier springs, would you?

 

You can also set the stall speed for the consist together.  Just as you do for a single engine.

You can do them together, but if the stall power setting was considerably different, I think you'd get better results setting them individually.

 

You are supposed to set the individual ones first AND THEN set the stall for the TRAIN.

Thanks for the continuing comments.  I now see three possibilities:

 

1) Have each locomotive unit with the same TMCC number, but set their stall speeds individually, one at a time on the track.

 

2) Have each locomotive unit with the same TMCC number, but set stall speed on both at the same time with both on the track.

 

3) Give them different TMCC numbers, and set them up as a lash--er, multiple unit consist, and set a stall speed for the TRAIN of units.

 

Currently I am operating as #1, but this weekend I'll experiment with the other two options and see if it is even better.

Oops I think Bill slipped up...

I would have them be unique addresses, set the stall speed individually for them, then configure the MU and see how they run.

 

I don't have two Pulmore motored units to test, or I'd try Chuck's technique.

 

All methods tested. I got the best results from setting both with same TMCC engine number, and setting the stall speeds individually on the line operated by Legacy.  I may have to expand Legacy to the entire railroad. It really does run TMCC locomotives better.

 

So, that's the way they will stay. thanks, everyone for the advice.

Bill,

 

  Sorry, I sent the last ones I had to the curve.
