Train Crash

• Tram
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 on on 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.
The length of a tram or trolley may be determined by national regulations. Germany has the so-called Bo-Strab standard, restricting the length of a tram to 75 meters, while in the US, vehicle length is normally restricted by local authorities, often allowing only a single type of vehicle to operate on the network.
