There are two main types of signaling aspect systems found in North America, speed signaling and weak route signaling. [citation needed] Speed signaling transmits information regarding how fast the train is permitted to be going in the upcoming segment of track; weak route signaling transmits information related to the route a train will be taking through a junction, and it is incumbent upon ...
Timetable and train order was not used widely outside North America and has been phased out in favor of radio dispatching on many light-traffic lines and electronic signals on higher-traffic lines. The only railroads currently still using authentic train order operations is the South Shore line in Indiana and the LIRR in New York.
Guadalajara's light rail system, despite being only about 15.5-miles long, transported an average of approximately 268,500 passengers per day in the Fourth Quarter (Q4) of 2013, [40] translating into over 18,000 daily boardings per mile, which was the highest per mile boarding rate of any North American light rail system. The Xochimilco Light ...
Railway signalling (BE), or railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails , making them uniquely susceptible to collision . This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle.
The first such systems were installed on an experimental basis in the 1910s in the United Kingdom, in the 1920s in the United States, and in the Netherlands in the 1940s. . Modern high-speed rail systems such as those in Japan, France, and Germany were all designed from the start to use in-cab signalling due to the impracticality of sighting wayside signals at the new higher train spee

The following is a list of all light rail systems in North America, ranked by ridership.Daily figures for American and Canadian light rail systems are "average weekday unlinked passenger trips" (where transfers between lines are counted as two separate passenger "boardings" or "trips"), unless otherwise indicated.
