I was given a spreadsheet of railway data and the data is all broken down by each railway company. The request asks that they be able to turn/toggle on and off each railway.

Is there a way to configure ArcGIS Pro so that I would be able to physically turn on and off each point symbol in the TOC? Or is the only way to achieve this is to create 522 separate feature classes, add them to the TOC in APRX file, and then group them to achieve this?
The data for North America looks like this:
Currently, my TOC appears as per this segment:
