I just installed my first TPC400 on one of my two lines. Before having it I used one Cab1 remote to control both mainlines simultaneously by keying in the engine number that I wanted to control. I find that with the TPC400, when it is set in conventional mode, requires a dedicated Cab1, which I have.
So my question is: When the TPC400 is set to conventional mode and my other mainline is command mode that two Cab1s are required if I want to control a train on each simultaneously?
Thank you!

No, you can just address the command engine i.e. eng24 and get it going. When you want to return to your conventional loco, address the TPC unit, i.e. TR1. Its the same concept as operating two command locos with one remote, you have to
"toggle" back and forth via the adresses.
I've set the TPC to conventional, started a MTH locomotive conventional and got it running consistantly. Then I brought a command engine on the same track behind the one running conventional. Noting that speed control of the conventional effects the command locomotive, I would adjust the command locomotive accordingly. A lot of button pushing on a Cab1. 
There is a low voltage point where the command locomotive will drop out.

You can just reprogram the TPC as an engine and then you will be able to toggle back and fourth.
Thank you for the information! I'll practice my new button sequences.
