Pronunciation: [pˈɔ͡ɪntsmən] (IPA) 
The word "pointsman" is spelled with an "s" instead of a "z" despite the fact that the sound it represents is typically spelled with a "z" in British English. This is because the word originated in South Africa where the spelling with an "s" is more common. The IPA phonetic transcription of the word is "ˈpɔɪntsˌmən" with stress on the first syllable and the "t" pronounced as a distinct sound at the end of the first syllable.
Pointsman is a noun referring to an individual who works as a signalman, typically stationed at a railway junction or at any point where tracks diverge, intersect, or connect. The role of a pointsman is crucial in ensuring the safe and efficient movement of trains through the network.
A pointsman is responsible for operating the mechanical or electrical switches known as points, which control the direction that trains take at junctions. They ensure that these switches are correctly aligned to guide trains along the appropriate tracks. To do this, they use a variety of signaling equipment, including flags, lamps, and control panels, to communicate with train drivers and other railway staff.
Apart from their signaling duties, a pointsman also has an important safety role. They inspect and maintain the points and associated equipment, ensuring that everything is in proper working order. They are trained to identify faults or abnormalities that may hinder the smooth functioning of the rail network, and they promptly report any issues to maintenance teams or supervisors.
Working outdoors in all weather conditions, a pointsman must also be vigilant at all times to prevent accidents or clashes between trains using the same junction. They must closely monitor approaching trains, signaling for them to stop, slow down, or proceed according to the established railway regulations. Overall, their expertise and diligence contribute to the overall efficiency and safety of rail operations.
On a railway, a workman who has the charge of the switches or movable guiding-rails at or near a junction or station, to open or shut them on the approach of trains, as may be required.

The word "pointsman" originated in the late 19th century as a compound noun composed of two elements - "points" and "man".
The term "points" refers to the movable sections of a set of railroad tracks, which can be adjusted to guide trains onto different routes or tracks. These points are also known as switches or turnouts.
The term "man" refers to a person who performs a specific role or job. In this case, the pointsman is a person who operates and manages the points on a railway, ensuring that trains are directed correctly onto the desired tracks.
Therefore, the etymology of the word "pointsman" is a combination of the term "points", referring to the tracks, and "man", indicating a person who performs a particular task.
