What about upgrading the Orange Line to Light Rail?
Let me preface this blog post by stating I think bus service is wonderful, and I support a county-wide network of transit only lanes and busways.
However, I do not subscribe to the belief that a seat on the bus is as "good" as a seat on a train, nor do I agree with the choice of Metro to brand busways with official colors like the "Orange Line" and the "Silver Line".
The San Fernando Valley seems to be left out of mass transit planning in Southern California . Meanwhile the entire San Gabriel Valley political structure is united and is eagerly anticipating two or more Gold Line extensions eventually on the northern prong to Montclair and even Ontario Airport and on the southern prong to possibly Whittier and/or Duarte . The reason for this is obvious. With our oversized, too populous, too few legislative districts at the national, state, county and municipal level, many of the politicos who represent the southern San Fernando Valley also represent and have their power bases in the Westside. All of their attention is going toward extending the Purple Line to the Westside, which of course is the most needed and highest profile transit project in planning.
Just how did this former rail corridor end up as a busway anyway?
From Wikipedia:
The majority of the Orange Line is built on part of the formerSouthern Pacific Railroad Burbank Branch right-of-way. This had passenger service from 1904 to 1920, with stations at several locations including North Hollywood and Van Nuys. It had Pacific Electric Red Car service from North Hollywood to Van Nuys again from 1938 to 1952.
The right of way was purchased by the Los Angeles County Transportation Commission (now Metropolitan Transportation Authority) in 1991 along with several other rail road right of ways across the Southland for future use in transportation projects.
The California Legislature passed a law in 1991 introduced by Alan Robbins which prohibited the use of the corridor for any form of rail transit other than a "deep bore subway located at least 25 feet below ground". Later Los Angeles County passed Proposition A in 1998, promoted by supervisor Zev Yaroslavsky, which prohibited Metro from using its county sales tax funding to build subways anywhere in the county.
With subway and light rail now off the table the only option left to develop the transit corridor was to build a busway.
The "Orange Line" busway is already at capacity and shows the limits of BRT. The San Fernando Valley deserves an east-west rail project that connects Warner Center with the Red Line (and could potentially be extended east through Burbank and Glendale to meet up with the Gold Line in Pasadena ). Since the San Fernando Valley politicos are focused elsewhere, it is up to you and me to remind them that simply extending a busway north doesn't cut it. Perhaps some of you could lobby to get VICA (Valley Industry and Commerce Association) behind an east-west line and a north-south line for the San Fernando Valley . If the San Gabriel Valley is getting two light rail lines, the San Fernando Valley deserves no less.
In Measure R which was approved by voters in 2008, there is a project study for a north-south transit project connecting the Orange Line with Wilshire/Westwood through the Sepulveda Pass. If this were a rail project, many local transit advocates see it logically being extended south down to LAX and north up to Sylmar Metrolink. That would take care of a needed north-south rail line for the San Fernando Valley .
What about east-west rail travel? The most obvious solution is to upgrade the existing Orange Line to light rail.
I asked the incomparable Kymberleigh Richards (http://transit-insider.org), member of Metro's San Fernando Valley Governance Council, her thoughts on the issue and the possible challenges and here is what she had to say:
Here are the problems that would be faced:
1. You would need to retrofit the busway without seriously disrupting existing service, otherwise what's the point? You wouldn't want to inconvenience the existing passengers by forcing them to a slower alternative during construction. The most likely way to proceed would be to close one segment at a time, one lane at a time, then cut grooves into the pavement down to the roadbed and install the rails so that they were flush with the pavement (like a grade crossing, only along the entire alignment) then reopen the lane to bus traffic. Service would continue to run with only a minor delay by using the remaining open lane to run both directions, with flagmen. Grade crossings would require a bit more logistics, especially the major arterials like Van NuysBlvd.
2. You would have to use a low floor light rail vehicle in order to avoid having to retrofit the existing station platforms. This means the existing light rail cars would not be compatible with the Orange Line. So there would be a third fleet of LRVs at Metro; heavy rail subway (Red/Purple), high floor/high platform light rail (Blue/Green/Gold/Expo/Crenshaw) and low floor/low platform light rail ( Orange ). So forget any Orange Line extensions that would interline with something else.
3. Because of the constraints of construction, the technology will have to be something other than overhead catenary for power. Installing that would require full busway closure for longer periods of time, which puts us back to inconveniencing passengers during construction. Third rail power, like the Red/Purple Line, is also out of the question because of the open-air operation (you can't have passengers in danger of making contact with the electric source). A DMU, like the San Diego system, is going to be far too expensive for this and brings constraints of its ownto the process. So either you need a protectedthird rail(very costly; they are experimenting with this in some of the Middle Eastern countries, where cost is no object) or a self-contained, rechargeable on-board power source. Perhaps some type of storage battery that could plug in at the layovers?
4. The street running segment between Canoga Station and Warner Center would have to be negotiated with traffic engineers at LADOT. I doubt they'd give up traffic lanes for the light rail, and I don't savor the idea of running light rail in mixed-flow traffic.
And of course, you'd have to do an entire new scoping/AA/EIR/EIS and figure out where the funding is coming from. Just that last part (the $$$) pretty much means all the Measure R projects would have to be underway and near completion before you could start programming funds for an Orange Line upgrade.
No one has ever done a busway-to-light rail conversion. We'd be breaking new ground, which is why there's no hard research available on the subject.
