what do they have in houston? is it a light rail or a commuter rail? from what i've heard it only runs around downtown and a few areas outside of it. please explain to me my misinformation.

Well, I doubt Capitol Metro wants it to fail, but certain people like Gerald Daugherty and others did. We had a good plan in 2000 for a true light rail start, but it was voted down. The heavy rail commuter rail that we have now is very different from light rail, and is really inconvenient to where it goes and the way it'll function. It'll help some people in North and Northwest Austin who choose to ride it. The East Side station at Plaza Saltillo is great, but there's nothing else around it and bus service there is nil. So basically it'll be a park and ride at best. The commuter rail won't go south of the river until something is done about Union Pacific in moving it to another line elsewhere, probably east of town. How can you have a good rail transportation system when only half the city is served? You can't. MIEK, are there any plans to expand the current commuter rail? Where would it go? Is there a map showing future routes?
The difference between light rail and heavy rail (commuter rail like what we have now) is that light rail trains have more frequent stops. A train might go 3 to 6 blocks and then stop at a station, and then have another station another 3 to 6 blocks away. So for a pedestrian that's a manageable walk to do to the next station and makes the train convenient. Light rail is also better suited to follow streets' routes sharing lanes with cars and is better able at making hard turns. Light rail trains have a tighter turning radius than heavy rail trains, so they can go through downtown streets and make a turn pretty much the same way a bus can.
But heavy rail is really no different than the Amtrak train that runs from Dallas to San Antonio. Our heavy rail commuter train will make less frequent stops, maybe only one every 2 or 3 miles (or farther). And it cannot follow street routes and share vehicle lanes or make tight turns. Think of our commuter trail just as you do the Union Pacific freight trains that go through Austin. They run on the same track as they do and have exactly the same turning radius. It's like asking an elephant to do the work that a horse should be doing.
The other difference is that light rail trains are silent. They make NO noise. I've seen the light rail trains in Houston and the only noise is the sound of the wheels gliding on the track. Light train trains are powered by electricity, so they're virtually silent. They also have no exhaust which is nice if they're going through downtown streets, since they wouldn't contribute to air pollution.
Heavy rail, like our commuter rail, uses diesel engines. Again, no different than a freight train really. They're noisy, lumbering and smell like anything burning diesel fuel does. Light rail trains and heavy rail trains are completely different animals.
EDIT: I knew MIEK would beat me to it.
