It's grim up north (London)
Plus there was the tragedy at Bethnal Green during the war, but that's more to do with people using the station as a shelter than the line itself.
Balham had a nasty one in 1940
Wikipedia said:During the Second World War, Balham was one of many deep tube stations designated for use as a civilian air raid shelter. At 20:02 on October 14, 1940, a 1400 kg semi-armour piercing fragmentation bomb fell on the road above the northern end of the platform tunnels, causing a large crater into which a bus then crashed. The northbound platform tunnel partially collapsed and was filled with earth and water from the fractured water mains and sewers above, which also flowed through the cross-passages into the southbound platform tunnel, with the flooding and debris reaching to within 100 yards of Clapham South. Sixty-five civilians in the station were killed, according to the Commonwealth War Graves Commission (CWGC)[5] - although other sources report 68 - and more than seventy injured. The damage at track level closed the line to traffic between Tooting Bec and Clapham Common, but was repaired rapidly with the closed section and station being reopened on 12 January 1941[6]. There is a memorial plaque in the station ticket hall commemorating this event, although it incorrectly states that 64 lives were lost, as do some other sources.
e2a: the London Transport Museum claim 111 died.
