出發之鐘 喺函館本線函館車站用。『出發之鐘』喺1990年左右開始，喺日頭嘅特急「北斗」號、「超級北斗」號、「初雁」號、快速「海峽」號出車嗰陣用。不過1997～2002年嘅3～10月嗰陣快速「海峽」號曾經改做「叮噹海底列車」，當時嘅出車音樂也改咗做『叮噹之歌』。
The departure bell is used at Hakodate Station on the Hakodate Main Line. The "Departure Bell" began around 1990 and was used during the daytime for the limited express "Hokuto", "Super Hokuto", "Hatsugeun", and Rapid "Strait". However, in March ~ October 1997~2002, the "Strait" was changed to "Jingle Submarine Train", and the music of the train at that time was also changed to "Jingle Song".
