SamTrans Dumbarton Rail Corridor Bridge - from Redwood City to Facebook (Menlo Park) to East Bay

you're not seriously suggesting that nimbys would prefer an elevated viaduct?

Only if it is a monorail!

Yes in fact.

If done well, elevated viaduct gives new parkland and rejoins sections of cities that are divided.

You'd prefer grade level? Diesel smoke, horns, suicides, traffic backups? Or a Berlin-wall-style berm?

Where is that from? Is this a proposed image of the corridor?

Answer, click to the third slide here: https://www.railway-technology.com/proj ... -victoria/
Google Images reverse search found it, after I used a Tineye match and cropped it down to the result since the actual link was expired! Joys of stale facebook/instgram image drops.

Victoria appears to be really excited about Level Crossings Removal. The original of the photo is probably in here somewhere. It's an infinite scroll page, and there are scores of projects if you wait for the delay. https://levelcrossings.vic.gov.au/media/image-gallery

Example only:

what are we even talking about anymore?

the nimbys in Atherton want the tracks to be buried below the ground, and there won't be any diesel smoke on any of these corridors in another decade.

Yep, having delivered pizzas in Palo Alto, and briefly lived in East P.A., long ago, I can say with whatever expertise that the tracks are considered a fact of life in the South Bay. If they'd originally been built closer to the 101 freeway, along the Bay, rather than inland towards El Camino Real, it might be possible today to imagine an elevated structure, opening up waterfront vistas with parkland underneath. But the immense size of the 101 would forgo even that possibility.

The tracks are through residential and commercial areas that are highly resistant to change and every square meter is valuable land.

It's easier to imagine a grade-separated rail corridor much further inland, along the World's Most Beautiful Freeway, the I-280 Junipero Serra. Or at a higher cost, coasting on pylons above the 101.

LOL, Lensovet thinks a viaduct is impractical but he will float the tunnel idea!?!

@kitchin A viaduct along 280 would indeed be a beautiful ride, but it would miss all the Peninsula population and work centers whose riders will justify such an expense. A viaduct over 101 would be more practical and may be the easiest to construct. And if freight is routed over a rebuilt Dumbarton (as was the point of my first post) then you benefit with a lighter, steeper, cheaper viaduct whereever it is built.

Neither idea is practical. The viaduct was floated as a way to placate nimbys, which it won’t do. A tunnel is what they want, and anything else is just a waste of time and money. The tunnel, too, is a waste of time and money.

I am not “floating” anything myself.
