| 摘要： | At approximately 1:46 PM EDST June 21, 2007, Metro North Railroad northward commuter train Number 1926 derailed Control Car 1697, three additional coaches and Engine 842 (pushing) on the Waterbury Branch in Milford, CT. The train derailed at the south end of the hand operated switch to the Ballast Track at Mile Post 0.6. Train 1926 was operating at 47 MPH. A total of 38 passengers and crew were onboard the train when it derailed. Two crew members and two passengers experienced minor injuries. The weather was clear, temperature 72 degrees and it was daylight. The Rail Traffic Controller in Grand Central Terminal, New York City had previously instructed the driver on an on- track Track Patrol vehicle to leave the hand switch to the Ballast Track in the reverse position for a following movement of a Ballast Regulator to clear in that track. The Ballast Regulator instead cleared the Single Track at a hand switch known as Track 5 at Mile Post 0.3. The Rail Traffic Controller mistakenly thought Track 5 and the south end of the Ballast Track were the same location and recorded the Single Track as clear. A southward train, Number 1963, then trailed through the misaligned switch and damaged it. The engineer of the southward train did not observe the switch in the reverse position as his attention was diverted away from the track by activity at the Gulf Oil Highway Crossing just beyond the hand switch in the reverse position. Train 1926 later approached the switch and observed it in the reverse position but was unable to stop in time. The train entered the side track and derailed. Probable cause: The cause of the derailment was a misaligned switch. |
