As you approach Fair Oaks on the Gold Line today, near this location, you parallel the UP, and the old "telltale" to warn of the "low clearance" under the "old" Fair Oaks bridge (replaced by the present bridge, I believe sometime in the 70's,is still there.

UP and ATSF shared two of the bridges across the Pasadena Freeway at the Barbara Ann Bakery, and in South Pasadena. Both of those were as a result DT bridges and are still used by the Gold Line today.

The grade was steep out of LA through the Arroyo Seco, so freight almost never went out that way eastbound. You can even find films of steam helpers pushing pulling that grade to Pasadena, that were cut off at Lamanda Park, on the name passenger trains eastbound out of LAUPT. But, CQP used to send plenty of westbound ATSF freight trains across the 2nd District to Hobart in the 80's. He grew up next to the tracks in Arcadia, and the only freight action we got as kids, were rides home on Shack's local, and chasing horse trains to Santa Anita depot.
