I'm sure the UP passenger train was part of the local Rail Fest. I know somebody at UP in North Platte and they took me on the train with them. The cars are nothing fancy but they are rather nice. The upholstery had little UP logos in it and it just gave you the feel of what it was like in the hey day of railroading. The employees could not justify the cost of operating such a train except UP operates it with the excuse that it is for public safety education.....which it is. If you get on the train you have to listen to a railroad safety lecture while you ride. They actually give some startling statistics on how many people are killed at railroad crossings and next to the tracks. MOST railroad fatalities are not at crossings but people trespassing along the tracks on railroad property. The railroad officially calls those fatalities as trespassers on railroad property who stepped in front of the train...(suicides) A surprising number of them along the rails.
I take it that the train was some sort of a rail fan journey? The last time I saw any UPRR passenger equipment, it was on a siding in a rail museum.
