I don't know if this has been mentioned before, but if a train seems somewhat incongruous for a team named "Astros," it's because when they built the new park the owners seriously considered changing the name. Apparently "Astros" was too dated.
"South Texas Railmen" was the reported winner, and the ballpark reflects that Old West theme. Fortunately (IMHO), ownership came to its senses before actually making the switch.
