From a Recent tread. TMCC 101
If you can find a CAB-1/Command Base, the original TMCC offering, here is a link from the Lionel website. A 48 page manual that was part of the Cab-1 handheld/Command base offering. The complete guide to command control. Click on the underlined phrase to link.
Here is a link to the Legacy Control System V 1.5. 88 page manual
Both manuals have just about everything that is involved with the two systems. Basic wiring to multiple unit/locomotive operations.
Another important part of the system is the Track Power Controller. It allows for Conventional control using hand held remotes.
Edit/add: The TPC (Track Power Controller) has the ability to interface with QSI/MTH Proto1 and Proto2 in conventional mode. Noted in this publication. Simple commands like horn/whistle, couplers, etc. are available via the Cab1 handheld control buttons. Pages 17,18,19.
There are other control devices related to accessory and block controls, that more or less piggy-back off either of the two command systems.
Lots of infomation in those three underlined phrases.
Have fun
Mike
