The station master (or stationmaster) is the person in charge of a railway station, particularly in the United Kingdom and many other countries outside North America. In the United Kingdom, where the term originated, it is now largely historical or colloquial, with the contemporary term being station manager. However, the term station master remains current on many heritage railways, and also in many countries outside the United Kingdom, notably the extensive Indian Railways network.
Historically a male occupation, women were sometimes appointed to the position, and the gender variation station mistress was sometimes employed in such cases. In the United States the role is commonly termed station agent.
The station master is responsible for the management of other station employees and holds responsibility for safety and the efficient running of the station. The term was historically employed across stations of all sizes, leading to variation in the precise role. At a major city terminus, with potentially hundreds of employees, the station master's duties would focus on personnel management and public relations. At smaller town and country stations, with a more limited staff, the station master would have far more customer interaction with travelling passengers, and would commonly deputise for other members of staff in their absence.
On the contemporary British rail network a station manager at a major station has duties very similar to those described above. The more localised role of station master at small country stations no longer exists, with group station managers taking responsibility for two or more stations. In very rural areas a station manager may be responsible for a large number of stations, or even for all the stations on a local branch line.
Historically the station master was deputised (in his absence) by an Assistant Station Master (ASM). In large stations this might be a full-time position. In smaller local stations the ASM title was often attached to another post, such as senior booking clerk, or even head porter. On heritage railways the ASM role is often unchanged from this historic role. The ASM post also continues in many Commonwealth nations, and other countries which have experienced British influence. In contemporary British railway operations the station manager is commonly deputised by one or more shift station managers.
The number of other employees at a railway station varies according to size. A historic station master would typically manage a number of booking clerks (responsible for ticket sales and financial auditing), porters (responsible for platform safety, luggage transportation, and cleaning), and often ancillary staff in catering, left luggage, and maintenance roles. Although technically part of the engineering department, a station master might also have day-to-day management of signalmen in the station's signal box.
