Since us in z scale as well as other scale's may be facing very few new offerings over the next year or so. How well does the SD75 locomotives run with the newer SD70 ACe and ES44ac locomotives. Thinking it might be smart to buy a few stand ins until everything in the future becomes clearer... Thanks for your input...

If you dismiss DCC decoders to allow speed matching, I think you'll find the following to be true: 1. The SD70ACe's and ES44AC's won't match up as well with the older SD70M/SD75I locos with the 8V Faulhaber motors. This includes the following list of locos: - 6101 - NS
- 6102 - UP
- 6103 - CN
- 6104 - UP Flared & Flagged
- 6105 - BNSF Warbonnet
- 6106 - BNSF Heritage II
Read more: azlforum.com/thread/1032/maximum-locomotive-voltage#ixzz5Ol5jhelH2. The SD70ACe's and ES44AC's should run well with the newer SD70/70M/75M locos. (ie Every SD7x series loco not explicitly named above) |

Thank you that answers the question which units to purchase to run as a trailing unit for stack train. Occasionally i still see a war bonnet or H2 SD75 running as a trailing unit on the BNSF. But if they don't run well with the newer stuff forget it...

There are still two options...AZL's later runs included an ATSF Warbonnet (so "ATSF" on the side instead of "BNSF", but otherwise the same scheme) and also another run of BNSF Heritage-II. Both of these are still widely available. (in fact, I have one of the newer Heritage-II locos for sale at the moment.)

Will do some more research into it. Hate to spend a couple hundred dollars on a locomotive that will not run with others... Especially when there are options out there...

I pretty well just explained everything out with regards to the SD70 series locos. Not sure that any more research is going to yield a different answer for you, but good luck.

They run just fine together...after a few modifications of course. The very best thing you can do is use DCC and get yourself TCS AZL4 decoders when you start lashing_up units together, paired with an NCE Power_Cab. Not only will you be getting 100% smoother control, momentum, and better operation, you now can access independent + multiple lighting functions per unit; nothing against DC but...it's 2018...at this point, DC should only be used for breaking in units on test loops setup on the kitchen table imo. 
The most annoying problem I see often is when you start running AZL units back_to_back, or in any consist arrangement, with* the proto-plow-pilot installed, is how stiff the couplers are. You don't want a giant gaping wound-like_hole in the front of your engine...put on the pilot you paid for! otherwise, don't even bother mentioning "prototypical"  ; this will cause derailments into easements & curves between the trailing unit and first few freight cars. With minimal sway/forgiveness, it will literally pull and lift wheel sets just over the rail-head into a curve. To fix this, open-up the couplers on the pilots and freight cars and exacto the whiskers back on the couplers by 3/4. [you can always swap em' out to an mtl 905 and suffer the slinky-bounce effect...and/or change them out on freight cars to full throttle-bowser bucklers].
