New Cab 1L and the old support equipment

[dougdagrump]

Yes you will need the new Command Base to go with the Cab1L unless you have a Legacey base. As far as being compatable with the TPC-400 and SC-1, I can't say with 100% certainty that it will be compatable but my guess is that it will be since the Cab-1L and Command Base are compatable with TMCC. You have some minor entry differences but fully functional operation. 

Edit: From the owner's manual for the Cab1L & command base.　

The TR button on your CAB-1L can control two very different things—"TRains," or remotely controlled "TRack" power accessories. You can run both from the same CAB-1L, as long as every one has a unique ID#.

Let’s talk TRACK power for a moment. Lionel offers a variety of accessories which provide remote control over track power. These enable you to remotely turn on and off power to all or some of your layout. In addition, some of these accessories allow you to vary the AC voltage applied to the track so you can run conventional (non-command controlled) locomotives on a command layout. You may also use variable track voltage to fine-tune performance of your accessories and command-controlled locomotives.

 

To operate these track power control devices (for example, a LEGACY PowerMaster), you’d assign them a unique TR ID#. Then they’d be addressed in the same way you’ve learned to operate a locomotive: by pressing

 

TR

and the ID# of the track power accessory you want to control. Refer to your track power accessory manual for specific information on setting these IDs and other operating instructions.

 

[overall]

Will the new Cab 1L run the older equipment like the TPC-400 and the older SC-1's? I have both of those things now.

I am thinking about getting the new Cab 1L because my Cab 1 is getting to where some of the buttons don't always work. I just want to make sure it will work with the stuff I already have. I understand that I will need to get a new command base to go with the Cab 1L, is that right?

Thanks,
