On 10/8/19 NS 25A was heading south through Hamilton OH at approximately 1:30 am. There was a dense fog in the area and it is unknown what signals awaited the train as it made its way south and then east on the NS New Castle District. What is known is that just beyond the second signal they came to on the NS (Mosler Holdout) sat the rear end of NS 143.
NS 25A failed to stop and rear ended the 143 damaging both lead locomotives from 25A and the car immediately behind them and the three rear cars of the 143 derailing them. The eastern most car was a wood chip car and was re railed.
The western pair were tankers containing Butane gas and they took the brunt of the hit. Both cars and locomotives were smashed together and could not be separated at the scene. Once the main body of the trains were pulled away from the wreckage they drug the whole pile up back west to a siding track called the Hamilton Yard Track. Here it took quiet a while to separate. This video shows the rest of 25A being taken back North to a siding in Camden, the locomotives being pulled to the siding, and the separation of the cars and locomotives. The crew is ok from both trains with one member of 25A going to the hospital with minor injuries.
