Skip-stop
From Biocrawler, the free encyclopedia.
Skip-stop is a public transit service pattern. Some stations along the line are designated as minor stops. Half the trains in one direction stop at every other one of these stations, and the other half stop at the others.
In some systems, like the New York City Subway, these are considered as two separate services (J/Z and the former 1/9). On other systems, like the Southeastern Pennsylvania Transportation Authority's lines, they are distinguished by lights on the train, and stations skipped by half the trains are designated "A" and "B" stations depending on which trains stop there.
