No one else cares for you like these hash browns do! The train night crew was treated to breakfast for dinner including (how can you ever go wrong with) bacon, scrambled eggs, hash browns and homemade bread. #hashbrowns |
Rick has almost finished his "built from scratch" GoPro flat car with head lights. This should make for some pretty cool night time videos! |
Video: Tonight we ran a train looking for track issues. It confirmed last week's fix at the south end of TwentyMile bridge district is now smooth-as-glass. |
However, tonight we had issues at the north Anchorage yard switch. Several cars derailed as they pass through the switch. Shown above is caboose 1087's front wheel set dropping down from the rail. |
After scrutinizing a long list of factors, Rick found caboose 1087 and a tank car had wheel sets with different tread widths (W). To help see this clearly, I put two whites lines at the bottom of the left wheel. I then put the same two lines at the top of the left wheel. You can see the top tread width is smaller. Once we swapped the top wheel set out for one with a wider tread width our derailments ceased. |
