But that would have required an existing rail authority (like Amtrak) to participate. With Amtrak out of the picture, the coalition doesn't have enough time to come up with another proposal to meet LaHood's April 4 deadline. In most countries, such as the United Kingdom, the distinction between a tramway and a railway is precise and defined in law. In the US and Canada such street railways are mostly referred to as trolleys. The key difference between a railroad and a trolley system is the latter running primarily on public streets, whereas trains have a right of way separated from the public. Often the US style interurban and modern light rail are confused with a trolley system, as it too may run onto the street for short or medium long sections. In some languages the word tram also refers to interurban and light rail -style networks, in particular Dutch. B-double In the United Kingdom Section 83(1) of the Railways Act 1993 defines "train" as follows: The Northwest Territories allows LCVs of up to 31 m (100 ft) in length. These vehicles are restricted to specific destinations in Hay River and Yellowknife. LCVs do not operate north of Yellowknife.
