Unless Lionel is going to make sensors available for the multitude of other hobbyists that use different track systems I can't see being interested in the LCS system, so far the catalog only shows a piece of fastrack with the sensors and a lot of proprietary cabling. The sensor track also looks like it has it's own power source that needs to be plugged into a wall outlet or perhaps that is for the WiFi module I didn't get a close enough look at that item.
Expected that Lionel would lead with it's own track system, and perhaps something to follow for other big-name track companies. I just don't know enough about LCS yet to see if it's a "good match" for exotic layouts that are typically built with the likes of Gargraves, MTH ScaleTrax, Ross, and Atlas-O track systems. LCS may be more appropriate for modest layouts built with FasTrack. Worth watching this space closely... that's for sure.
