The two comm lines (formally the communication lines) have been installed on Lenawee Express. These lines extend from tower to tower between the heavy and light sides of the lift. They contain phone lines and they also contain intra-lift communication avenues. All chairlifts are loaded with lots of safeties and all of these safeties talk to the control system at the drive station. In case of LenX, the drive station is at the bottom of the lift.
