Houston-North Shore Railway

Reporting mark: HNS
"The last interurban railway to be built in the United States, the Houston North Shore Railway Company, built twenty-six miles from Houston through Baytown to Goose Creek in 1927. It operated until 1948. The line, no longer electric, is now an important industrial branch of the Union Pacific between Houston and Baytown and is virtually the only vestige of the Texas interurban network that remains."
