Track upgrades on Surfliner route?

This recent photo shows two tracks with concrete ties through Irvine, CA (I believe this is a 90 mph stretch for the Surfliners). Has Amtrak been upgrading the track recently? Who actually owns the tracks, and are all upgrades financed by California? And last but not least, do they use track laying equipment similar to what Amtrak uses on the Northeast Corridor?

i am sure they do, i mean all RR equipment that lays down track and ties are the same. most of the line in Mass. is double track, concrete ties. Mp 194.5 - 205 is where Acela can hit 150 mph

The track the Surfliner's on is actually wooden ties, while the one next to it is concrete. The wooden trackbed is from the Santa Fe days, where the concrete is just a couple years old.

There is TONS of upgrading work getting done on the Surfline route, here's a photo from up front somewhere near Oceanside, CA in recent weeks.

Looks to me like the BNSF sees economic advantage in doubletracking the San Diegan route. Seeing advantage, and having either sufficient capital in hand or on loan, means it's time to lay track.

Is BNSF paying for it , or the state of Califionia ?

When did BNSF (or predecessor ATSF) dump the line, or did some political subdivision of the Peeple's Republik of Kalifornia come in and exercise Eminent Domain???
