SP line-up for El Paso Nov 16, 1979
The holy grail for railroad photographers would be a document that showed what trains were running, and when to expect them.
This document actually exists. It’s called a line-up. Railroads create them so crews, maintenance-of-way and operations can have an idea what to expect in the next 24 hours or so.
An SP crewman gave me this line-up one day as I was hanging out near the El Paso passenger depot. By my count, there are 21 trains showing, 13 from the east through 6:30 PM, and 8 from the west through 6:30 A.M. the next day.
My ballpark guess for train count through El Paso in 2010 would be 60.
