Union Pacific 4-6-6-4 3802 leads a 15 car Gold Coast Express (UP 2nd 24) near Hermosa Wyoming in 1952. Otto Conrad Perry photo, from my collection.

UP 3802 leads the LUE50 or LUE51 local on a Sunday afternoon at Stauffer, Utah.

That lead SD40-2 may be 'foreign', but it is a much more common sight in these parts than the home road unit behind it - one of CSX's much-loved BQ23-7s.

The daily Newark- Roseville manifest has been routed over the Cal-P line (usually goes over Altamont Pass) and strolls through Jack London Square on a beautiful May afternoon.
