Suffice it to say that any extension of
HF that is expected to be a daytime trip between FTW and NEW, would of necessity break the connection between the
Eagle and the
HF at FTW too.
Using the schedule of the old
Lone Star just as a rough guide, a train leaving KCY at 6am could make it to FTW at around 7pm, and roughly the same vice-versa. This is likely a good yardstick since the scheduled running time of the
HF between FTW and OKC is not that different from that of the
Lone Star. BTW, the
Lone Star used to make the same stops between FTW and OKC as the
HF.
Just to give you all a short recap of the
Lone Star, between OKC and KCY it used to stop at: Guthrie, Perry and Ponca City in OK and Arkansas City, Wichita, Newton, Emporia, Topeka and Lawrence in KS. It used to leave KCY southbound at 2:20am pass through OKC at 8:20am and arrive in FTW at 12:50pm, from where it continued on to HOU arriving at 7:55pm. In the reverse direction it departed HOU at 7:40am, FTW at 2:30pm, OKC at 6:45pm and then on to KCY at 2:55am. Southbound it passed NEW at 4:15am, northbound at 11:15pm. It was a train that was more convenient for Oklahomans (Ponca City at 6:35am southbound and 8:45pm northbound) and Texans and not that convenient for Kansans and Missourians.
If
HF were merely extended keeping its current schedule then the northbound would not be a convenient train even for the north end of OK. If the old
Lone Star schedule were used then it would be more convenient to the north end of OK. Due to the reality of time keeping or lack thereof by the Eagle, the FTW departure would of necessity have to be shifted by at least to two hours later than the
Lone Star schedule, which will make it arrive into Ponca at 10:45pm, not too bad, but NEW would then be at 1:15am. Potentially this makes it feasible to need only one consist for the service, but cutting it close at both ends, so realistically it will still need two consists. Going to KCY will in all cases need a second consist, no matter which schedule one uses.
The flip side of this is that if the Eagle connection is broken then a future extension to HOU becomes unfeasible. In all cases an extension to HOU requires an additional consist.
So the bottom line then is, if KS is shelling out the money then the full daytime schedule would probably take precedence breaking all connections. OTOH if TX is chipping in more the
Lone Star-like schedule would make more sense. No matter what you do there will be some winners and some losers. OK seems to be a winner no matter what
