Houston streetcar line
The author failed to mention the line Houston has had in place since 2002, or before. It is very effective, comfortable and has a large amount of people who use it. It connects all the downtown business with the Medical Center and is being expanded Southward to the Reliant Center / 610 Loop regions. Although I no longer live in Houston, I have friends and my grown children who use it several times a week. It is great to have in times when gas prices are on the rise, wind power is being expanded and anything to reduce greenhouse gases is needed.
Without a solid, affordable electric car with the necessary power stations emplemented, the streetcar, and use of interurbans also, is a very logical form of transportation. And, streetcars are not so rigid as one thinks. They are very viable and they do not eliminate the use of the streets for other traffic. The Siemens system used in Houston is very efficient and blends well with other means of transportation.
