Is it a #switch or a set of #points ? Depends on where you live for one thing.
The design of a system to merge two sets of tracks so that a train can go on either has not really changed much in the past 150 years, at least in the overall design.
I love these old Victorian diagrams with the letters (call-outs as they say in tech publishing) that tie in to the descriptions.
