VARIABLE TYPE ADDITIONAL RAILWAY LINE SYSTEM

摘要

PURPOSE: A variable form additional railroad system is provided to reduce a congestion of a train by installing one additional railroad in a bottleneck section. CONSTITUTION: An additional railroad(110) is installed in a bottleneck section. The additional railroad is used as an up line in a congestion of a train. A first additional railroad crossing(120) connects the additional railroad with the up line. A second additional railroad crossing(130) connects the up line and a down line. A bidirectional signal(140) is installed on the up line. The bidirectional signal generates a signal into bidirectional for an up train or a down-train. A point machine controls a conversion of the first and the second additional railroad crossing.
