Would someone please move the train?

For those of us who were out and about in Greeley at 5:30 am, you might have been stopped by a train. The train was blocking traffic at 22nd street down by 4th avenue. I noticed this when I left my place at 5:30. I drove down by the train and found it not to be moving with no obvious reason why. I decided that it was odd and moved on. When I returned to my place an hour later and found the train exactly where it was an hour ago I got curious. I drove down to where the engines of the train were. The engines happened to be very close to where the tracks intersect at 37th St, over a mile away. I walked up to one of the engines and just stood there for a minute. After a little bit a window opened up and I saw a man's head. I notified him that he was blocking 22nd street. He didn't seem happy to be talking to me and quickly belted out that there was nothing he could do about it. I retorted that I merely wanted to let him know and went on my way. When I checked the distance on the way back to my place, it was 1.3 miles between 37th and 22nd street. Which definitely puts the train at over a mile in length. I wonder if there are restrictions on the length of trains that Union Pacific is allowed to have?
