tramrail

noun tramrails · tram rail

1. An overhead rail forming a track on which a trolley runs to convey a load, as in a shop.
2. A street railway laid in the streets of a town or city, or an interurban railway for local traffic, on which cable cars, or trolley cars, etc., are used, in distinction from an extended railway line for trains.
3. A grooved rail (one of at least two) laid in a street for trams to run on. Ordinary rails are used on off-street (reserved track) sections of tramways. The line from Nyon to La Cure (17½ miles) was opened in 1916, and is on independent track throughout, leaving the road immediately after passing under the Swiss Federal line from Lausanne to Geneva, where grooved tramrails with tie-bars give place to steel-sleepered track.
