Jack Delano's train has stopped at Melrose to meet two eastbound trains. The caboose is near the same crossing that you saw on the previous page. Melrose is at milepost 681.
This is what the end of every freight train should look like. Just like every sentence should end with a period, a train should be punctuated with a caboose at the end.
The first eastbound train has gone by and Jack's train will move further up the siding after filling the tender with water. At this time this subdivision was operated by train orders. CTC would be installed in 1945. Note the old cantilever signal bridge with upper quadrant semaphore signals. In 1928 ATSF added a desk interlocking panel at Melrose, NM with 4 levers to control the 2 passing track switches.
The second eastbound train rolls by and Jack's train is on the move again. In the picture below, the water tank on the right stood until around 2012. It is now gone.
