This post fits neatly into the "old news" category as the events I am noting took place something like 4+ years ago, but it will provide some closure for anyone else who has not been paying attention. The West in general is known for its general lack of towers compared to the East and Midwest. Certain area of California had more towers than most of the west, but the number was still rather low and from that level there was been a high level of attrition as those, largely wooden, towers were closed and demolished. Most of So Cal's surviving towers were in the general vicinity of Union Station with TERMINAL TOWER and MISSION Tower being the most well known.
However a bit to the south were two attitudinal towers on the former ATSF Chief route, HOBART and REDONDO. Each governed a single track diamond crossing of the busy AFST main line.
Built in 1906, REDONDO was located at the ATSF crossing of the Los Angeles and Salt Lake Railroad, that became Union Pacific's primary route into the Port of Los Angeles. The redwood frame tower was ultimately equipped with a GRS Model 2 pistol grip interlocking machine and the junction controlled the southern end of the LA passenger rain engine and car facilities. The tower was closed in 2001 when a passenger flyover was built over what would become the Alameda Rail Corridor route to the port of Long Beach that converted the sleepy UP main into a 3-track intermodal superway.
Located in a fairly isolated area the tower was generally left along for the next 15 years until some time after December 2016 the tower either caught fire or was tagged for demolition. By June 2017 the tower was a husk and by Octover 2017 it was gone. In 2001 the Alameda Corridor Transportation Authority was nice enough to commission an historical pamphlet with a selection of interior photos.
HOBART interlocking is located about a mile east of REDONDO at the west end of Hobart Yard where the UP San Pedro Branch crossed the former ATSF main line. Also equipped with a GRS Model 2 pistol grip power frame, the tower was a bit more modern than REDONDO being made of concrete. Closed in 2002, its location at a major yard and non-flammable construction gave HOBART a fighting chance of survival.
Unfortunately between May and December 2017, a fire started by homeless persons gutted the tower. Although the concrete structure was still generally sound, the tower was now on the glidepath to demolition, a fate that was ultimately carried out in May of 2019.
Of course the fates can occasionally smile on old interlocking tower. DAYTON AVE tower, located at the southern end of the Southern Pacific Taylor Yards north of Union Station, was saved by relocation not once, but TWICE.
When Metrolink was building a new maintenance facility in the 1990's, DAYTON AVE tower was relocated from its initial site on the LA River to a site adjacent to the Metrolink Facility entrance on San Fernando Rd.
Later in ~2013 when this site was tagged for a new development, DAYTON AVE tower was moved again to a new location 3 blocks to the southwest on part of Metrolink's rail storage lot.
At the start of this article I mentioned TERMINAL TOWER and MISSION tower. TERMINAL TOWER is currently used as some sort of MoW or signaling support base part of the greater LAUPT complex. The long closed MISSION tower is less critical to operations, but is likely owned by a government entity and has been generally protected by local preservation groups and general governmental paralysis. I recently found a 1980 vintage film on Youtube documenting ATSF operations at MISSION tower with its GRS Model 2 pistol grip type interlocking machine.
Enjoy.
