Subject: mainline running line support railw. He gives two options for likely ride quality improvements, such as the introduction of "tangential" switch points in turnout upgrades that aimed to significantly reduce entry "jerk" and Welded Spring Manganese (WSM) frogs in Emerging HRS shared access corridors, which offer the ride comfort benefit of continuous mainline running line support, while avoiding the incremental signaling and control cost assosiated with moveable point frogs.не могу понять, тут речь идет о сигнальных опорных линиях или о рельефе полотна? спасибо |
