Para 135 emphasized that the trillion damages are out of the citizen's pocket, and stressed that the wrong tenders jeopardized human life as well as the loss of money.
WHAT IS SIGNALIZATION?
Each rail vehicle has its own safety type. Since the trams enter the traffic, they are driving with sight and the tunnel metros are provided with an interlocking system for driving. The control center collects all line-length equipment information and decides whether a train is allowed to enter a rail zone according to this information. When any train enters a scissor or rail zone, the zone is locked until the train leaves that rail zone and no operation is allowed. In this way, trains are not allowed to enter the other block from the block, thus preventing collisions.
