I think this is the reason why TexRail feels more like a novelty as opposed to true commuter rail. No one has the time to wait an hour between trains.
Really???
Real commuter rail in many places throughout the USA run morning and evening trains in one direction only, for the day shift to or from downtown.
What TexRail and TRE provide is better titled regional rail, with trains going in both direction all day long and into the night. Yes, it would be nice if the trains ran twice an hour all day, but is that convivence to passengers worth the cost of seeing mostly empty trains all day twice as much?
I'm pretty sure if the hourly trains were overflowing with standing room passengers all day long TexRail would run trains more often. What we have here is a chicken and egg what comes first scenario problem.
I lived in SF Bay Area and the CalTrain system ran more frequently than once an hour; it was more like 15 mins. The stations were around commercial and residential areas and the trains are double decker and full most of the day. To me, that is what commuter rail is supposed to be. I want to see if happen but I don't see how our will get better tbh. The stations are not near anything except the most used ones (T&P, Central, Grapevine and Teriminal and the connection to the airport is convoluted and shortsighted.
Believe me when I say this but I do want a successful commuter train and airport connection. I have lived in several cities with good to decent public transportation and I have actually rode TexRail for no reason other that to pay the fare even when I wasn't planning on using it because I want it to stay around. However the only way for it to be successful is that it has to have a purpose of getting people somewhere and that purpose has to be as easy to use as possible. In regards to your Chicken vs the Egg comparison I believe what we have in our current scenario is a chicken who can't connect to the hen house to lay eggs on time.
