No worries I understand can can be confusing and overwhelming. What you’ve come across is my one gripe with the LionChief line. You still have to use their remote/ Bluetooth or the universal remote. In your case no cab-1, Cab-1L, or Cab-2 will run a plain LionChief locomotive. The newer LC + 2.0 locomotives close this gap with TMCC already installed also giving you that option. If you do have TMCC or legacy locomotives then #2 and #7 are the keys for crew talk and tower com respectively.
I would only get a Cab-1 (grey remote) if you get it for a steal. I’d highly recommend a Cab-1L set (blue remote). Either way you MUST have a base. If you come across a old cab-1 set be sure it has a base and not a original PowerMaster (PM-1) that will not help you in your situation.
