Skip-stop
Skip-stop is a public transit service pattern which reduces travel times and increases capacity by having vehicles ''skip'' certain ''stops'' along a route. Originating in rapid transit systems, skip-stop may be also used in light rail and bus systems. "Skip-stop" is also used to describe elevators that stop at alternating floors and hence also used to describe building designs that exploit this design and avoid corridors on alternating floors. Rationale Skip-stop service is one solution to increasing train speed at minimal cost. In rapid transit systems in the United States, stations tend to be close together (approximately in 1976), and so trains struggle to reach high speeds. The New York City Subway for example, the slowest in the United States, travels at an average speed of . Trains on the same track cannot pass each other like buses can, and so to increase speed, changes can only be made in terms of headway, or in which stations are served. Skipping stations incre ...

Chicago "L"
The Chicago "L" (short for "elevated") is the rapid transit system serving the city of Chicago and some of its surrounding suburbs in the U.S. state of Illinois. Operated by the Chicago Transit Authority (CTA), it is the fourth-largest rapid transit system in the United States in terms of total route length, at long as of 2014, and the second-busiest rail mass transit system in the United States, after the New York City Subway. In 2016, the "L" had 1,492 rail cars, eight different routes, and 145 train stations. In , the system had rides, or about per weekday in . The "L" provides 24-hour service on the Red and Blue Lines and is one of only five rapid transit systems in the United States to do so.The four other rapid transit systems in the U.S. that provide 24-hour service in at least some parts of their systems are the New York City Subway, Staten Island Railway, PATH, and PATCO Speedline. The oldest sections of the "L" started operations in 1892, making it the second-olde ...

Skip-stop On The Chicago "L"
The Chicago "L" used skip-stop service, wherein certain trains would stop only at certain designated stations on a route, from 1948 to 1995. It was implemented as a way to speed up travel within a route, and was one of the Chicago Transit Authority's first reforms upon its assumption of the "L" operations. Background The main part of the Chicago "L" was built in stages between 1892 and 1900. Originally the purview of four private companies, those companies merged to form the Chicago Rapid Transit Company in 1924. There was very little spending on expanding rapid transit within the city from the 1910s to the 1930s, and by 1936 Manhattan had more miles of rapid transit than the entire city of Chicago despite having a tenth of the land area and a lower population. By the 1920s, the "L" was criticized for its mismanagement, in particular Chicago's lack of a subway system in contrast to other cities such as New York and Boston; construction of a subway was a plank of William Emmett ...

Limited-stop
In public transit, particularly bus, tram, or train transportation, a limited-stop (or sometimes referred to as semi-fast) service is a trip pattern that stops less frequently than a local service. Many limited-stop or semi-fast services are a combination of commuter rail and express train. The term is normally used on routes with a mixture of fast and slow services, and can differ in meaning, depending on how it is used by different transit agencies. The main benefits of limited-stop or semi-fast services is the ability to utilise skip-stop calling pattern to maximise capacity along the line, as opposed to a commuter service stopping at every station which slows trailing express trains down. Railways On railways, the layout of the tracks and number and length of platforms at stations normally limit the extent to which a blend of fast/semi-fast/slow services can be operated. Australia In Australia, particularly in Brisbane and Sydney, limited stop services are formed by commute ...

Chicago Transit Authority
The Chicago Transit Authority (CTA) is the operator of mass transit in Chicago, Illinois, United States, and some of its surrounding suburbs, including the trains of the Chicago 'L' and CTA bus service. In , the system had a ridership of , or about per weekday as of . The CTA is an Illinois independent governmental agency that started operations on October 1, 1947, upon the purchase and combination of the transportation assets of the Chicago Rapid Transit Company and the Chicago Surface Lines streetcar system. In 1952, CTA purchased the assets of the Chicago Motor Coach Company, which was under the control of Yellow Cab Company founder John D. Hertz, resulting in a fully unified system. Today, the CTA is one of the three service boards financially supported by the Regional Transportation Authority and CTA service connects with the commuter rail Metra, and suburban bus and paratransit service, Pace.

Central Business District
A central business district (CBD) is the commercial and business centre of a city. It contains commercial space and offices, and in larger cities will often be described as a financial district. Geographically, it often coincides with the "city centre" or " downtown". However, these concepts are not necessarily synonymous: many cities have a central ''business'' district located away from its commercial and or cultural centre and or downtown/city centre, and there may be multiple CBDs within a single urban area. The CBD will often be characterised by a high degree of accessibility as well as a large variety and concentration of specialised goods and services compared to other parts of the city. For instance, Midtown Manhattan, New York City, is the largest central business district in the city and in the United States. London's city centre is usually regarded as encompassing the historic City of London and the medieval City of Westminster, while the City of London and the trans ...

MAX Light Rail
The Metropolitan Area Express (MAX) is a light rail system serving the Portland metropolitan area in the U.S. state of Oregon. Owned and operated by TriMet, it consists of five color-designated lines that altogether connect the six sections of Portland; the communities of Beaverton, Clackamas, Gresham, Hillsboro, Milwaukie, and Oak Grove; and Portland International Airport to Portland City Center. Service runs seven days a week with headways of between 30 minutes off-peak and three minutes during rush hours. In 2019, MAX had an average daily ridership of 120,900, or 38.8 million annually. Due to the COVID-19 pandemic, which impacted public transit use globally, annual ridership plummeted, with only 14.8 million riders recorded in 2021. MAX was among the first second-generation American light rail systems to be built, conceived from freeway revolts that took place in Portland in the early 1970s. Planning for the network's inaugural eastside segment, then ...
