Union Pacific 9 locomotive monster train Byers Canyon, and Bond, Colorado

The freight trains keep getting longer and longer. Caught this monster train passing through Byers Canyon. This is with out question the longest train I have ever seen pass through the Moffat Route. Train was so long it busted in half earlier in the day (probably because there was no pusher locomotives). Eight powered locomotives is the maximum allowed for normal operations (dead locomotives do not count). You can also add pusher locomotives in the rear for some steep uphill grades. Lots of ancient coal cars on this train. These cars along with the GP15 locomotive could be heading to the scrap yard.
