在2008年全台鐵路（不含捷運）地下化全線完工後，也象徵台灣鐵路跨越到另一個時代，該鐵路隧道也成為全台最長鐵路隧道，汐止到板橋端全長共22.7公里，不過這樣的鐵路隧道長度在世界排名上，卻連前10名都排不上。深耕鐵路研究的YouTube頻道「鐵道事務所」，近日介紹前5名世界最長鐵路隧道（計算不含捷運、地鐵），包含從倒序排名開始的中國莞惠城際軌道交通的松山湖隧道、南韓栗峴隧道、西歐英法海底隧道、日本青函隧道、瑞士聖哥達基線隧道 ，其中日本青函隧道，不僅是世界最長海底隧道，且一直到2016年，都還是蟬聯世界最長鐵路隧道，令人印象深刻。
YouTube頻道「鐵道事務所」的所長介紹，日本青函隧道全線共53.85公里，雖然海底隧道段僅有23.2公里，沒有西歐英法海底隧道的海底段多，但算總長來說，它仍然是世界最長的海底隧道，而青函隧道跨越了津輕海峽，連接日本本州青森縣和北海道，對於兩地之間有相當大的意義，因為在1988年青函隧道建成之前，旅客透過火車或是渡輪來往兩地，耗時超過4小時，若是遇上惡劣的天氣容易出現事故，他指出在1954年，就曾經發生「洞爺丸事故」，當時有5艘渡輪翻覆，造成1430人死亡，如今青函隧道的建成，便利性和安全性都增加不少。
