The Advantages of an Overhead Monorail
for Marin and Sonoma Counties

The problems with rail in Marin.  A rail system has been proposed for Marin and Sonoma counties as part of a solution to our serious current and future transportation woes.  Such a system, along with minimal highway 101 improvements, has been voted down once [twice as of March 7].  I believe this is at least in part due to some inherent flaws:

Due to the above points, it is highly unlikely that rail in Marin could ever provide convenient service to anyone except a select set of commuters: those going to and from just the right places and who can adhere to very limited daily schedules.

Marin/Sonoma monorail.  I would like to re-introduce the concept of a monorail for Marin and Sonoma counties.   A monorail system can address all the rail issues listed above and more.   There are so many potential advantages to a Marin-Sonoma overhead monorail system that I believe it is well worth investigating existing and near-term monorail technologies and their economics before limiting solutions to auto, bus, ferry, and rail.

Before continuing, I wish to admit that though I am a technologist and former electric car engineer, I am not a mass transit expert, and have only done a brief internet study of monorail systems.  Instead, I am mainly addressing broad strokes that are clear from the basic monorail concept and a few implementations.

Monorail advantages.  Below are a series of specific advantages.  Taken together, they add up to something quite remarkable: the possibility of an affordable, convenient regional public transportation system that could some day not only relieve the traffic on highway 101, but also on arteries like Sir Francis Drake Blvd, East Blithesdale, Miller Avenue, and similar arteries in Northern Marin and Sonoma.

  1. Overhead monorail can be beautiful, futuristic-looking, and fun to ride¾ with a panoramic view.  These factors can enhance Marin’s beauty, help increase ridership, and even attract tourists.  See appendix for images of existing systems.

  2. Because monorail can be overhead without added expense, objectionable noise, or obscuring light or views:

  3. A whole monorail system can be much less expensive to build and run than heavy or light rail.

  4. Stations need be little more than a platform serviced by escalators.  Station requirements are simple enough to allow innovative and varied solutions such as stations within buildings, stations combined with multi-level parking lots, etc.

  5. Like rail, monorail would work toward grouping new development within walking distance of stations, though many stations will still need integral parking lots.

  6. The Marin rail right-of-way can be immediately paved for busses, for immediate alleviation of current traffic woes, without preventing or delaying monorail construction.  Or they can be used for bicycles and pedestrians, as in another proposal.

    An earlier objection to the bus proposal was that it would preclude rail, as the bus system would have to be dismantled before rail construction could begin, causing a major transportation bottleneck until the rail came on-line.   With monorail, however, the busses could continue operating while the monorail system is built above, with construction occurring during non-commute hours.

  7. A monorail may be light enough to eventually be extended over the Golden Gate Bridge under the roadway, and into San Francisco over or near Doyle Drive.

    Good public transportation between Marin and San Francisco was once avoided at all costs due to fears of overdevelopment.   However:

  8. Judging from international monorail experience and the lack of ground-level right-of-way requirements, local unidirectional monorail loops¾ connecting to the regional service¾ may be inexpensive and attractive enough to eventually add around major Marin and Sonoma population and retail areas, lessening local dependence on the automobile and reducing air pollution.  An example would be a Southern Marin loop through San Rafael, San Anselmo, Mill Valley, and towns in between¾ to relieve bottlenecked Sir Francis Drake Blvd, the Miracle Mile, Miller Ave, Bridgeway, etc.  Towns like Santa Rosa, Sonoma, Novato, Tiburon, and Sausalito may be able to support their own tiny loops.
