After about a 9 hour MOW work window in the morning, to replace tie plates from Caliente up to tunnel 2, traffic was back underway once again at about 230pm. With such long work windows rail traffic can get backed up and once released there tends to be a fair amount of congestion on the hill. Here, overlooking the canyons west of Caliente, there is a southbound UP intermodal holding in Caliente for a northbound manifest to come off the hill. While waiting, another southbound UP manifest would climb up behind the intermodal and for some unknown reason, blow through a red signal and stop right before a MOW road crossing. All while this was happening the UP manifest, with a red Canadian Pacific locomotive, would drift down and come to a stop just before the signals seen at the bottom left of this image. Momentarily plugging the hill. They would hold this manifest to let two northbound intermodals coming off the hill eventually overtake it. So, while this scene here has 3 trains in it, there are 2 other northbound intermodals just up the hill at Bealville and Cliff, being put into sidings to hold for the two south bounds here to pass by. Also there are 4 other south bounds down the hill waiting to come up, including a short work train that was only a few hundred feet up behind the manifest that blew passed the red signal. It was an interesting afternoon to say the least. Those long 9 hours of waiting finally paid off in the end.
