Glossary - V

Varnish A passenger train. Wooden passenger cars used to be given many coats of varnish. Vestibule The enclosed area at the end of a passenger car where the side doors are located. Early passenger cars had only an open platform. Around the 1880s narrow-vestibule cars came into use, with a vestibule only as wide as the passageway between the cars. The full-width vestibule followed soon after. Volt A unit of electrical pressure. Commonly, 0 to 9 volts of DC are used for Z scale model railroading, 0 to 14 volts DC for N and HO scale, and 0 to 20 volts DC for large-scale model railroading.
