I have preordered the Base3. I currently use a Base2, Cab2 and several Cab 1l's to control my layout. I have several TMMC locos, but mostly MTH proto1s, Williams and Lionel conventional (a couple from my childhood!). I use Powermasters and TPCs connected to my Base2 to control track voltage when running my conventional locos.
I have noticed many times that the Lionel Base 3 info given out by Lionel broadly states you can run all of the Lionel locos ever made with the Base 3 and Cab3 app. This is often repeated at various places on the internet. For most of us using Lionel remote control devices since the beginning we all KNOW that you need a Powermaster or TPC in addition to the Cab(whatever) to control track voltage with your handheld device. The need for this to control conventional locos was mentioned routinely in Base2/Legacy descriptions by Lionel. I don't see that in their description for the Base 3.
I was excited when the Base 3 was announced that they seemed to be saying the Base 3 would have track voltage control built in. I don't remember Dave even addressing that issue on a facebook presentation about Base3/Cab3. I asked. It is OK that Base3 won't directly control track voltage but not noting that you need some add on device could be misleading.
BTW, I think I bought my TPC's from the basement of one of the 'inventors' of TPC when I was in grad school in Detroit around 1974-76. At least, that is what I am gonna let myself believe!
Peace to all and have fun with your trains!
