Night service (public transport)

Night service, sometimes also known as owl service, is a mode of public transport service operated during the night hours. As an intermediate approach – between providing full service around the clock and stopping services altogether – it provides more limited service during times of lower passenger volume, saving resources and allowing for maintenance on primary transportation systems. They typically offer fewer routes and less frequent service. Night-based services may be differently branded compared to daytime services. Examples are London and Chicago, where overnight buses are prefixed with an "N" for "night". Another common way to distinguish night services from their daytime counterparts is dark-colored line numbers. Some cities apply a different fare structure for night services from their daytime services.

Characteristics
24-hour, continuous rapid transit operation is practiced in some cities, most notably the subway in New York City, which essentially renders night services unneeded. Many of New York City's buses also have 24-hour operation; and around the world, night services may be provided by virtue of 24-hour services on daytime routes, as does Berlin on its "Metrotram" routes.

Where it exists, night service is generally much more limited in geographic coverage than daytime services, with fewer lines and perhaps routes over different paths from daytime services; routes serving more stops than during the daytime; or the night terminus may be in a different place. Networks may run longer routes than daytime services, sometimes combining two or more daytime routes, which may use interchanges to reach the same outlying districts. Night services usually also run less frequently. For example, according to the New York City Transit Authority's Service Guidelines Manual, New York City buses are required to operate at least every 30 minutes all times except late nights. Local bus frequencies during late night times (defined as 1a.m. – 5a.m.) are required to operate at least every 60 minutes.

Because of much longer intervals between services than during the day, night routes often offer guaranteed transfers to other lines or transit modes (such as regional and intercity rail). To ease planning, many cities use a central hub where all lines converge at a specific time. This makes the line map of many night services look like a wheel with radial lines to the center and some additional lines connecting the outer ends (or running along a ring road outside of the city center). For example, many London night bus routes converge on Trafalgar Square.

Local services are operated in most part by Transports Metropolitans de Barcelona (TMB), although other bus services are operated by several private companies under common names. Nitbus (es) is the name of Barcelona's night metropolitan bus network. As of June 2024 there are 21 lines in the network (numbered N0-N9, N11-N20 and N28), operated by two different companies: Tusgsal (es) and Mohn. The buses that are part of the Nitbus fleet operate between 22:20 and 06:00 (depending on the line; each is governed by different schedules), with a frequency of 3/4 buses per hour (that is, a frequency of 15/20 minutes). All Nitbus lines (except N0 and N19 routes) stop at the central square of Plaça de Catalunya, so it is possible to change lines.
 * Madrid:
 * Urban transport, i.e. journeys that take place within the municipal territory of Madrid, are operated by the Empresa Municipal de Transportes de Madrid (also known as EMT Madrid). There is a dense network of bus routes which operates 24 hours a day. Special services called the "N lines" are operated during nighttime. The buses in Madrid are the only public transport system available around the clock as the metro network closes down between 02:00 and 06:00 am. Night buses began in Madrid in October 1974 with 11 lines. From 2006 to 2013 while the Madrid Metro was being upgraded, a night bus named Búho Metro (es), or Metro Owl, also existed in Madrid whose network simulated the lines of the Metro, but above ground. This service only operated on Friday, Saturday, and holiday eves and line numbers were denoted by an 'L' prefix. As of November 2023, EMT Madrid operates a network of 30 night lines (es) (popularly called 'owls', or búhos in Spanish) which operate from 23:45 to 06:00 (approx.). These routes are numbered N1 to N28 + NC1 and NC2. Their frequency is every 35 minutes on weekdays and every 15–20 minutes on weekends. Most night lines in the network depart from Plaza de Cibeles in the centre of Madrid, except the N25 and N26 which depart from Alonso Martínez. The buses departure times coincide with those of other lines to allow transfers. Night lines have the same fares as daytime lines, and the same tickets can be used.
 * Intercity transport, i.e. journeys that go between different municipalities in the Madrid region, are operated by CRTM. The inter-urban buses (autobuses interurbanos), commonly known as Green Owls (Búhos verdes), travel further afield than the regular owl buses and connect Madrid with the cities of the periphery. As of June 2022 there are 40 such routes (but only the N101-N102 and N202 have at least one departure every hour, seven days). Green Owl buses are identified by the letter N followed by three numbers (e.g. N101). It has been noted that real-time indicators at bus stops usually display only the number of a route, and not the "N" at the beginning, which can be a cause of confusion for visitors, as the route 101 can have a completely different destination to the route N101 (for example).

Most night buses operate Mon-Sun (with an increased frequency on Sat, Sun nights and nights before Public Holidays) between approximately 01:00 and 05:00/06:00. Some routes operate as frequently as every 20–30 minutes, such as route 96 (01:18 - 05:53) whereas others such as route 396 operate every hour (02:17-04:18). Many night routes have irregular timetables. Tickets cost the same day and night.

Since 2007, some S-Bahn night train lines provide a continuous 24-hour service from Friday morning until Sunday evening. A regular daytime ticket is sufficient for the use of the ZVV night network. All night buses and night S-Bahn trains are marked specially with the letter «N». The night services operate on Friday and Saturday nights, general holidays and some special occasions.
 * Rest of Switzerland: At weekends, passengers can travel by train at night in many regions and urban areas throughout Switzerland. These services are known by different names in different areas of the country, but include Nachtexpress, Moonliner, Noctambus, Mobinight, Pyjama Bus and Afterbus.

The night service on weekends was extended to the ferry lines in February 2020. Apart from the Metrobüs, which has the same night fare as daytime, all night lines cost two ticket price.
