 On December 6, 1917, the French ammunition ship SS Mont-Blanc blew up following a collision in Halifax Harbour, a tragedy known as the Halifax Explosion which killed nearly 2000 people.Although numerous accounts of the Halifax Explosion erroneously state that the North Street Station was destroyed, it was only damaged, albeit seriously, and quickly resumed service.On the morning of the Halifax Explosion, the Ocean Limited had just departed and the local train from Truro had just arrived.
