conventional vs new Lionel Legacy BOTH POWERED AA UNITS

Model number would help.

Are all the switches on the bottom of the engines correctly set ?

What happens if you just put one engine on at a time ?

All switches are on top & run switch is only one on,all others off. When leading A unit only is powered in neutral lights & sound work. As soon as I  push direction button cab light blinks & engine does not move. When trailing A unit is by itself it quietly moves forward or reverse. I only use MTH Z-4000 transformer. I had the same problem with Lionel's FA2 BOTH POWERED AA LEGACY ENGINES & sent them back. Literature still says they will act conventionally.

Model # 2033260

Which FA's? They did the exact same thing?

Do you know anyone with TMCC or Legacy to see if the lead unit actually works at all. Is it a freak chance you have 2 defective sets or are there more? (IIRC Lionel had issues with the PA's and RS-11's that reset to engine 1 when powered off, but they ran.)

My question was deleted because I originally posted under Lionel Three Rail.

Here's my question and I pasted the original replies from the following members:                                   WesternPacific2217,                                                                                                           Putnam Divison                                                                                                                         MartyE

And, may I ask Putnam Divine to repost the video?

Thanks again.

Page 58. http://catalogs.lionel.com/2022/BB/   I have not purchased Legacy, does anyone have experience on how well these engines are able to pull a load of train cars and are they reliable?

First Member: Reply by WesternPacific2217  To have the best experience with a Legacy Locomotive you'll need a Legacy base and Legacy Cab2 remote, or you'll be missing a lot of features. Better yet, wait for the new Base3 to start shipping, you can have it all!

I have 7 Lionel Legacy locomotives from catalogs 2008, 2009, qty 2 2010, 2011, 2012, and just recently from 2021. I run them often, and only one issue with 1 of the 7 locomotives and it was a bearing in the one of the motors. My 2008 is a WP F7 ABA set, only one A unit is powered, and it pulls 9 freight cars, or 5 aluminum passenger cars just fine. That includes a 2% grade on my layout, and it the powered F7 just cruises up the grade like it isn't there.

That said, I find my Legacy locomotives very reliable, a bunch of fun, and powerful. With 2 powered A units you should be able to power just about any consist you can make up. If Lionel had offered a F7 Southern Pacific in the Black Widow paint scheme, I would have ordered a set.

Second Member: Reply by Putnam Division: These F7s are from 2017……but with the powered B unit added in….and, very reliable….. (attached video was deleted.)

Third Member: Reply by MartyE If they are anything like the F3s, they should pull just fine.
