台鐵地下化留幾軌
這個問題請先去做點功課好嗎?
地下化留幾軌都是要站站停的
有必要嗎?
台鐵 南港-松山-台北-板橋
都是站站都停的
台鐵之所以要排待避是因為每班列車停靠站不同, 導致不待避會讓後方直達車被堵住
可是松山跟台北是全停站, 也就是說南下列車通過南港之後都會停松山跟台北
那麼不管後面的自強號還是前面的區間車都會在松山減速停靠
理論上在加減速與極速不要差異太大的情況下, 不會有待避的問題
區間車的性能其實也不輸自強號, 要這樣排當然沒問題
所以台鐵才要不斷更新列車, 減少性能劣化的莒光號跟復興號
只要讓列車性能都可以達到高水平, 那麼南港 - 松山 - 台北間就沒有待避問題
一小時內塞個十班車都只是小意思, 也能達成台鐵捷運化的目標了
相對於這個區間, 南港到七堵間就只有汐止停靠對號列車, 汐科五堵百福都不停
所以前面的區間車一停汐科, 後面的自強號就慢下來
區間車一到汐止就要待避等自強號通過後才開
很明顯這一段做好三軌化就能有效舒解待避造成的問題
