Sense: noun/1
Commuter train is the most general term for a train that runs regularly between the suburbs and a city centre, used especially by people going to work. Suburban train is largely interchangeable but slightly more common in British English — it focuses on the geography (the suburbs) rather than the activity of commuting. Commuter rail refers to the whole system or network rather than an individual train: for example, 'the city is expanding its commuter rail network'. Local train is a broader term that can mean any train that stops at all or most stations along a route, not only suburban commuter services; it may also include urban metro trains. In everyday speech, people are most likely to say 'I caught the commuter train' or 'I caught the 7:15 commuter train', specifying the time for clarity.

Etymology
Commuter train is a compound noun formed from commuter (a person who travels regularly between home and work) and train. The word commuter itself comes from commute, which was borrowed from Latin commutare (com- 'together, completely' + mutare 'to change'), originally meaning 'to change or exchange'. By the mid-1800s, commute had developed the sense of 'to travel regularly between home and work', especially via a season ticket that allowed daily travel at a reduced fare. The compound commuter train emerged in the late 19th century as cities expanded and rail networks began offering dedicated services for daily travellers.
