Final answer:
A track connection that enables trains to move from one track to another by using two switches is called a railroad turnout or a set of points.
Step-by-step explanation:
The connection between two adjacent tracks, which allows for crossing from one track to another and consists of two switches, is known as a railroad turnout, also referred to as a "set of points". Its primary purpose is to provide flexibility in the routing of trains by connecting tracks that may not necessarily be parallel. A typical turnout includes a pair of linked tapering rails, known as point blades, that can be moved laterally to direct a train onto one of two tracks.
In physics, a track connection between two adjacent tracks which are not necessarily parallel is called a crossing. It consists of two switches that allow trains to change tracks and cross from one track to another.
When a train approaches a crossing, the switches are set in a specific configuration to guide the train onto the desired track. The switches can be manually operated or controlled electronically.
For example, in railway networks, a crossing can be used to divert a train from one track to another, allowing it to switch lines or change direction.
