Number 90 posted:I see by the train number in the indicator of the steam engine, that you are interested in UPRR Trains 5 and 6. These were UP's mail trains to and from Los Angeles, and carried a rider coach. I used to ride No.6 on a ticket. Like Santa Fe Trains 7 and 8, the passengers were mostly deadheading employees, but they would accept paying riders to and from regular stops.
Santa Fe's 7 & 8 usually carried the rider coach or combine on the rear. In my version of 7 & 8 there's a baggage car on the rear, only because it has red lights on the back and I haven't put them on the combine car yet, so the combine rides just in front of the baggage car. I'm guessing UP followed a similar practice with their mail trains.
