That train has to be the lowest tech airport transportation between terminals on the planet as it is like 1950's Lionel train sophistication. As a Houstonian it truly is embarrassing compared to basically every other airport in the world.

Hardly anyone knows it is there. It was made back in the day when you left security to change terminals.

There's another much newer train you can take. But, the damn thing still works and has been great dealing with all of the construction.

It's throwback vibe is what makes it fantastic.

If you ever get stuck at IAH and get tired of sweating and smelling other people in genpop, take that inter terminal train to the Marriott hotel and work from the upstairs lobby. It's quiet, they got the A/C cranked, clean restrooms and restaurant downstairs.

Same technology as the WEDway People Mover at Walt Disney World.

From Wiki:

The Subway is notable as the only WEDway people mover built by the Walt Disney Company outside of a Disney property. It uses much of the mechanical technology used by the Tomorrowland Transit Authority PeopleMover, an attraction in the Magic Kingdom's Tomorrowland. The design permits the trains to make tight corners that are necessary along portions of the basement route. Like their Disney counterparts, the trains are completely unpowered, relying on linear induction motors in the track for propulsion
