[[London]] has multiple commuter rail routes:
* The [[Elizabeth line]] runs on a {{convert|22|km|abbr=off|adj=on}} east–west twin tunnel under central London ([[Crossrail]] project) as its central core section.
* [[Thameslink]] brings together several branches from northern and southern suburbs and satellite towns in to a high frequency central tunnel underneath London.
* The [[London Overground]], by contrast, skirts through the inner suburbs with lines mostly independent of each other, although there are several branches. The [[Watford DC line]], partly shared with underground trains, uses third rail, but parallels a main line using overhead wires. The [[East London line]] and [[North London line]] run at metro-like frequencies in inner London, which make them nearly indistinguishable from metro systems apart from the fact that the tracks are shared with freight trains.
* The [[Metropolitan line]], despite being part of the [[London Underground]], is a commuter rail route as it links the [[City of London]] to commuter towns outside [[Greater London]] such as [[Rickmansworth]], [[Amersham]] and [[Chesham]], where it runs to a timetable, being the only [[London Underground]] line with a public timetable published. It also shares tracks with [[Chiltern Railways]] main line services between London and [[Aylesbury]].

The [[Merseyrail]] network in [[Liverpool]] consists of two commuter rail routes powered by third rail, both of which branch out at one end. At the other, the [[Northern line (Merseyrail)|Northern line]] continues out of the city centre to a mainline rail interchange, while the [[Wirral line]] has a city-centre loop.

[[Birmingham]] has four suburban routes which operate out of [[Birmingham New Street]] & [[Birmingham Moor Street]] stations, one of which is operated using diesel trains.

The [[Tyneside Electrics]] system in [[Newcastle upon Tyne]] existed from 1904 to 1967 using DC third rail. [[British Rail]] did not have the budget to maintain the ageing electrification system. The [[Riverside Branch]] was closed, while the remaining lines were de-electrified. 13 years later, they were re-electrified using DC overhead wires, and now form the [[Tyne & Wear Metro]] Yellow Line.

Many of the rail services around [[Glasgow]] are branded as [[Strathclyde Partnership for Transport]]. The network includes most electrified Scottish rail routes.

The [[West Yorkshire Passenger Transport Executive]] run eleven services which feed into Leeds, connecting the city with commuter areas and neighbouring urban centres in the [[West Yorkshire Built-up Area]].

[[MetroWest (Bristol)|MetroWest]] is a proposed network in [[Bristol]], northern [[Somerset]] & southern [[Gloucestershire]]. The four-tracking of the line between [[Bristol Temple Meads railway station|Bristol Temple Meads]] and [[Bristol Parkway railway station|Bristol Parkway]] stations will enable local rail services to be separated from long-distance trains.

The [[Réseau Express Régional|Réseau express régional d'Île-de-France]] (RER) is a commuter rail network in the agglomeration of [[Paris]]. In the centre the RER has high frequency underground corridors where several suburban branches feed similar to a [[rapid transit]] system.

Commuter rail systems in [[German language|German-speaking regions]] are called [[S-Bahn]]. While in some major cities S-Bahn services run on separate lines exclusively other systems use the existing regional rail tracks.

[[Randstadspoor]] is a network of [[Nederlandse Spoorwegen#Types of train service|Sprinter]] train services in and around the city of [[Utrecht]] in the Netherlands. For the realisation of this network, new stations were opened. Separate tracks have been built for these trains, so they can call frequently without disturbing high-frequent Intercity services parallel to these routes.<ref>{{cite web|url=https://www.provincie-utrecht.nl/onderwerpen/mobiliteit/spoorprojecten#randstadspoor|title=Spoorprojecten|publisher=Provincie Utrecht|access-date=2021-02-09}}</ref> Similar systems are planned for [[The Hague]] and [[Rotterdam]].
