Now I know where you're going

The River Line veers to the right and follows the Hudson River down towards Bergen Yard and Croxton Yard. (This was the route of Amtrak's 2017 Autumn Express in the reverse direction.)

The Castleton Subdivision is straight ahead. The track on the left continues to the Berkshire Division to Boston and the track on the right goes to the Schodack Subdivison and Metro North's Hudson Line. The tracks meet at CP125.
