Edge dismisses critics as "people who want to see Hidalgo County and the Valley just remain as it is." He cites "lack of vision" as the biggest obstacle to bringing rail to the region.
"If you combine the Valley as a region, we're the fourth-largest metropolitan area in the state of Texas," he said. "We're larger than Austin. Austin has a train system."
Hidalgo County officials have yet to meaningfully endorse the rail system, perhaps seeing it as a faraway goal.
"Right now, my understanding is they're not looking for anything for implementation anytime soon," said budget director Sergio Cruz. But he added that planning for infrastructure far in advance is a "good idea."
"If you don't plan for them, then you're really going to be left out in the cold," he said. "If we already know what we're planning, 10 to 15 years from now, we'll be better off."
Cruz has yet to analyze the numbers to determine if the rail system is something the county will need or be able to afford in the future. Likewise, Hidalgo County Judge Ramon Garcia has yet to jump on board, but hasn't discarded his ticket, either.
"I'm maintaining an open mind and waiting to hear from them before making any conclusions," he said.
