Well, I was wondering about RR disasters around the world, let's share them. I'll put mine first On 29th november 1986, 6 UM12C No 4006, 4010, 4029, 4042, 4043 and 4044 ran away from Bang Sue Locomotive Depot and slammed into Hua Lampong Station. mg: Results, 4 people were dead. Investigation found that it was an operator and mechanical error. After that, SRT had to install dead man device to prevent this from happening again.
