I bought a pair of BN SD40-2 powered units. After gluing back on all the parts that lionel evidently forgot to glue, they added to my legacy set just fine, and run fine individually. I tried to create a "train" with them, and followed the legacy instructions. All the audio is coming from both of them... horn, bell, towercom, etc...
The icons on the screen appear correct (lead engine has the crown, horn and mic icons above it, the trailing engine has no icons). I've tried deleting the train and re-creating it with a different number, to no avail. This is the first time I've attempted this with 2 powered units, I'm a Legacy noob, but I tried following the directions on pages 60-62 of the manual. I didnt have the engines in PGM when I did this, but it looks like they should have been in run. Directionally, they appear to work (the trailer runs backwards just fine and the marker lights illuminate correctly), which leads me to think I did at least some of it right.
Any help?
Thanks
