These photos were taken from the back of Amtrak's Empire Builder on April 2, 2007.
On each page, you will see a description such as this:
028 North Lowell
- 028 is an arbitrary number to keep the photos in order.
- North indicates the photo is looking in the northbound direction.
- Lowell is the name of the interlocking. Intermediate signals are identified by their number rather than a name.
