Hope you don't think I'm lazy, maybe I could try this on my own, but I was wondering from your own experience. I was thinking of building an engine combo with a Legacy engine and a PW re-issue that has TMCC. How do you feel this lash-up would work? Pretty easy? Maybe it's a no brainer. thanks.

If you're talking about the PW re-issue with an AC motor, I doubt you'll be happy with the result. If you're going to run an MU configuration with TMCC and Legacy, or even with TMCC and TMCC, the locomotives should be similar in performance. It takes a lot more to get the AC locomotive initially moving, and the speed vs. power setting curve is quite different than can motored locomotives.

Yes that is correct. I was thinking of adding the new Legacy Texas Special powered B unit to mate up with my PWC Texas Special A unit, so I could have a smoking unit. The PWC I believe is an AC motor, so if this is not a smooth transition, I think you saved me some money.
Well, I've never tried it, but knowing the characteristics of AC and DC motors under TMCC, I can't imagine it being a satisfactory match.
I know this is not what you have , I am only giving this as an example. One of our club members had the early 4-8-4 northern with TMCC he got the latest Legacy 4-8-4 northern and wanted to hook them up in a MU. the results were not what he excepted. he went out and got another Legacy 4-8-4 northern.
This issue has been talked about before with me having a Conrail Legacy U30C with a Lionel Conrail SD-80 with odyssey. Could not get them to play "nice in the sandbox" together. One starts out quicker than the other so they were running at different speeds.
I even had an issue with a MTh converted Conrail SD-80 to TMCC with ERR. Can't get it to play with the Legacy but can get it to play with TMCC one but some success but still overly satisfied with those 2 operating together. Tried the nudge feature with limited success.
I basically buy dummy units to create multi-units to operate with another diesel. this way you have no issues with which engine will operate in sync with another.
I have yet to try an MU with DCS locomotives, but I've had very good results with Legacy. I've even MU'ed a Legacy steamer and a diesel, just to see if it would work. It was an odd looking combo, but they ran well together. I've MU'ed two similar diesels equipped with ERR Cruise Commanders, that worked pretty well, but not quite as smooth as the Legacy engines.
There is a Train TV show on the RFD channel (6pm Thursday) and much of the time the steam loco has a diesel to help when needed. This was also done in the early days of diesel when they did not trust the diesels. In this case the steam was the backup. Don

Even the exact same TMCC engines don't run well together in may cases because of the Odessey system. Learned from experience
I did see some videos with that arrangement, but they were more recent. We had a discussion here about the 765 and a diesel double-headed. It turns out they bring the diesel along so that they don't have to run the steamer on the long legs to bring it to a location, but not really for reliability.
I've found that Legacy-Legacy lashups work great but Legacy-TMCC lashups usually do not.
You can test it by creating the lashup but keep the two units uncoupled with a few inches of space between them. That allows you to see how different their start-up curve/speed is without stressing any motors or gearing.
