Lionel used to offer a TMCC module (6-14185) for controlling an operating track section. So far, they haven't offered an LCS version. Of course, the TMCC module could be used together with a 6-81326 LCS Serial Converter (SER2). But does it seem that it would work to use the relays of an ASC2 or a BPC2 to control an operating track section?
The Lionel LCS Accessory Switch Controller ASC2 6-81639 will control operating tracks.

Page 25 of the manual shows an example of wiring the ASC2 to an operating track
