 One of the drivers killed was Thomas Kitchen, who had been driving one of the trains involved in the accident at Picnic 18 months before.On 11 May 1887 the 5.30 p.m. train from Flinders Street station to Balaclava came to a standstill just before Windsor station because the outer home signal was at danger.When the signal changed to proceed, the train would not move because the air brake hose pipe between the locomotive and the first carriage had broken, meaning that the brakes could not be released.
