Level 0 is used on lines with conventional trackside signalling. Train drivers follow trackside signals primarily, with cab signals as back-up. UCS receives train fixed block occupation signals from track circuits and is shown as cab signals using digital signal processes. TOSU/LKJ is used to supervise speed limits and can only advise train ...
Kavach incorporates several key characteristics of the European Train Control System (ETCS) as well as the Indian Anti-Collision Device (ACD); however, it is considerably more cost-effective in comparison to ETCS. [7] Furthermore, unlike ETCS, Kavach is not intended to function as a replacement to traditional Lineside signals. While ETCS ...
Traffic cones, also called pylons, witches' hats, [1] [2] road cones, highway cones, safety cones, caution cones, channelizing devices, [3] construction cones, roadworks cones, or just cones, are usually cone-shaped markers that are placed on roads or footpaths to temporarily redirect traffic in a safe manner.

Most interlockings only have one controlled signal on each track.
