They are also called hi-rail -- from highway and rail, or variations such as high-rail, HiRail, Hy-rail, etc. They are often converted road vehicles, keeping their normal wheels with rubber tires, but fitted with additional flanged steel wheels for running on rails. The rail wheels are raised and lowered as needed. Purpose-built road-rail vehicles also exist.
