The lack of Sunday Service on TRE is important for FTW, but with DART running from Union Station in Dallas to DFW 7 days a week, there is no need for Amtrak to stop @ Center Point Station ! The fare on #22 is the same to FTW or DAL from SAS and Stations North,so Northbound Eagle pax could just book to DAL and ride DART to DFW to catch flights!
What Jim said. Plus, in a few years, the same will be true from the south end:
http://www.texrail.com/ It looks like the stars are aligned for TexRail. The federal government has issued the Record of Decision; there is enough funding to complete design and purchase land; agreement has been obtained from the track owners; complete funding is expected from the FTA in early 2016. They're targeting 2018, though 2019 is probably more likely. At that point, there will be no good reason for Amtrak to stop at Centreport.
One stop rides have always been an important aspect of ridership. If you are travelling from Marshall, Longview, or Mineola, then would YOU want to get out at Dallas with your bags, switch to the Red/Blue line for one stop, transfer to the orange line, with all your bags, ride 50 minutes on a crowded train to the Northern terminal of DFW where you need to transfer to a shuttle to take you to the Remote South parking area, where you hop on a shuttle that takes you to your terminal.Or, you could just stay on your nice comfortable long distance train for an additional 30 minutes, then switch to a shuttle that will drop you off at your airline.Situation (until TexRail) is worse from McGregor and Cleburne from the West. You get to Fort Worth. Ride 30 minutes past Centreport. Then add the transfers mentioned above.The more I think about it, Amtrak should be paying TRE to expand Centreport with full Amtrak ticketing and baggage service. THIS is what a National long distance railroad should be all about. Connecting communities to other transporation modes. In fact, the only downside that I can think of is that it could be so popular that they would either have to add a coach or risk medium-distance travellers blocking space from full run passengers.
