I purchased two Lionel N&S SD80MACs (which I love) with the intention of doing a lashup to pull my coal train. I then discovered (my bad) the Lionchief App does not support lashup, and the Universal Remote only for the exact same product number. Since my NS engines are 7219 and 7217 running a lashup with out Legacy control is not an option. So I only see two options at this time. One is to acquire another N&S SD80MAC and run both same road numbers together with the Universal Remote, the other is bite the bullet and get started with Legacy control.
The problem I see with option one (two of the same number while still workable) is no individual control of features like couplers or lights. The main question on Legacy lashup is, will one of the units become the primary so lights and couplers can be individually controlled on each unit? I'm looking for how does the lashup work with Legacy.
Have to note I do like the simplicity of the Bluetooth remotes which are easy for the grandkids and visitors to operate which is why most of my stuff is Lionchief except for my older transformer items and the two new LC2.0 SD80s. At the moment we're mostly carpet runners with a loop to loop and staging yard is in the TV room. Additional carpet routes get setup with routes down the hallway, into the bedrooms, under the beds, etc,.. Summertime will see the staging yard moved to the empty half of the garage with modules and bridges quickly setup in the garden and patio. Not keenly interested in the complexity of a Legacy system nor do I plan on having other lashups.
