What does mainliner mean?
A mainliner is a passenger train operating on a principal railway route, often between major cities and sometimes providing long-distance or overnight services. In this traditional railway sense, the word suggests a regular, important service connecting places along a main line. It is distinct from the more general term liner, which can refer to a large passenger ship or a train without necessarily identifying its route. The word also has a less common political meaning: a person who supports established or mainstream positions rather than radical or fringe policies. That sense often implies a contrast between central and peripheral politics. Although modern travel has increased the prominence of budget airlines, intercity trains, and other high-speed services, the term mainliner remains associated with the golden age of railway travel and with the idea of a dependable trunk route linking major destinations.

Where does mainliner come from?
The word is formed from main line, the principal route of a railway or transport network, with the suffix -er denoting a train that operates on such a route. Main and line entered English through separate histories: main derives through French from Latin mainus, meaning “chief” or “principal,” while line comes through Old French from Latin linea. The compound main line was established before the later formation of mainliner, which specializes the earlier expression as a name for a particular kind of train.
How mainliner is actually used
The railway sense is traditional and is especially associated with British and Commonwealth usage. The political sense is comparatively uncommon and should not be used to mean any supporter of a particular mainstream party without further context.
