The CC would only stop at Gilroy, San Martin, Morgan Hill to replace Caltrain service there; cross-platform transfers can be made at the existing SJ Diridon station. (The CC would be better off terminating at Hollister, but that's a topic for another thread.)Caelestornoreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-3807983244860483232016-06-22T15:37:35.946-07:002016-06-22T15:37:35.946-07:00As for eliminating the CEMOF double reverse curves...As for eliminating the CEMOF double reverse curves, Caltrain seems to be more keen on taking out two warehouses and the Arena parking lot to fix the curve.

I think stations with through tracks, a small storage yard/tail track south of Blossom Hill, would be needed. Also, as Capitol Corridor would be extended to Salinas by 2020, would some kind of transfer station needed at one of these stations?

In Nerima Ward in Japan, they are tunneling a portion of the Seibu Shinjuku Line to eliminate grade crossings, this on a line that carries much, much more passenger traffic than Caltrain. Of course, property rights are extremely strong in Japan, and tunneling is cheaper than in California.Andrew in Ezonoreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-38862666266232558812016-06-15T08:51:53.041-07:002016-06-15T08:51:53.041-07:00Yeah, just to add to that, structures are almost a...Yeah, just to add to that, structures are almost always the biggest part of construction costs, with land acquisition being only a small portion.

It's a very emotional issue, but once you get past the emotion it's a straightforward matter of a time, money and expropriation lawsuits. The eventual outcome is rarely in question.Clemhttps://www.blogger.com/profile/01374282217135682245noreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-48312202040356184942016-06-14T20:10:01.931-07:002016-06-14T20:10:01.931-07:00No it doesn't.

The peninsula corridor right-of-way is so generously sized that building new two-track-only infrastructure is short-sighted and potentially wasteful. Even if grade separations are initially built for two tracks, the EIR should study full-sized bridge abutments and retaining walls as needed to support future expansion, even if such expansion is not part of the project scope."<br /><br />The right of way is so Generous sized....<br /><br />Really!
