At one time did UP have to equip their locomotives with ATS inductor pickups in order to transverse ATSF trackage from the LA area up and over Cajon out to Daggett?
Here is a photo of the Aerotrain at Las Vegas with the pickup on the front truck.

Also, a eastbound UP publicity shot near Kyle Nevada where the ATS pickup is also visible.

PLEASE NOTE - Neither of these photos are mine, just found them around the net through the years

If anyone has any further info on the UP photo, as in what train this is (perhaps the "Pony Express") please post.
