SD10 557 was caught on the wrong end of derailment and couldnt return to Janesville. It was shut down and Gratiot and became a 150 ton ice cube. A week after the derailment, the track was repaired and the 506 hauled the 557 back to Janesville to thaw out. Later in the year, the 506 would be leased to and painted for the Wisconsin & Southern |
