LCS is a modular system. The parts you need are determined by what you hold in your hand to run LCS (Lionel CAB remotes and/or WiFi devices) and the actions you want to create on your layout. There’s one LCS component that must be included: PDI Cables. You just need one per LCS module. It connects the first LCS module to your Base3, and subsequent LCS modules to one another.
Use the table below to help choose the additional LCS products that make sense for your layout. Pick an action from the first column. Then read to the right to see which LCS module that does that job.
