This handbook briefly describes how growth of railroads and highways resulted in a proliferation of grade crossings and then discusses the variety of methods developed to warn pedestrians and vehicles of approaching trains. It is aimed primarily at providing railroad, state and municipal personnel with information which can help in cooperative efforts to improve grade crossing safety and efficiency. The book describes conditions and requirements at crossing; facilitates understanding of the elements of crossing systems; provides a compendium of existing grade crossing technology; serves as a guideline to aid in implementing improvements to grade crossings; aids in understanding and applying new technology; and serves as a basic text for training programs.
