Leverage modern technology, ffs! Magic free capacity everywhere, lower operating costs, and overall minimized latencies for all passengers at all times.<br />The only hard part is that we would need better track switches (with redundancy), but I am pretty sure we can get good ones from Japan.Andrewnoreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-7563073050642770952017-08-20T23:15:00.948-07:002017-08-20T23:15:00.948-07:00The travel demand could evaporate in an instant.

Cultural tides around the bay area shift every few years, and if everyone suddenly decides that SF is over, you could see ridership declined steadily until 2022.

Expanding beyond 2 tracks through this neighborhood is going to be met with as much pleasure as with PAMPA area. However, unlike the PAMPA area where there aren't viable alternatives, the aerial alternative runs over highway, so has less impacts, has roughly same speed/distance since it's essentially doing same S curve as current alignment, and given that CHSR's private ROW begins South of Diridon, it's not negatively impacting Caltrain.<br /><br />The cost of that segment will roughly equal the cost of expanding that section to 4-tracks after you factor in years of lawsuits and delays.<br /><br />To me, the only downside is that it requires greater expense north of SJ to bring the tracks up to that level.Martinnoreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-44389200239877110912017-08-15T16:42:08.197-07:002017-08-15T16:42:08.197-07:00Not happening.

It was mostly explaining to the CWG why the tunnel options they prefer are not going to happen. SJ City's main input is spending some money on tunnel consultants who will most likely agree with this conclusion. SJ must know this as already as they proposed the aerial alignment themselves back in 2010.<br />The HSR people were basically saying that you either need to do the aerial option or work around the operational limitations of the 3-track blended at-grade solution (including the wildest dreams of Amtrak and ACE), which I guess means doing things like what @Clem proposes. If you want the operational capacity of the aerial option at-grade, you need more tracks and that results in massive impacts. (The west option looks even worse than the east one from a brief glimpse...) Based on the gentleman at 1:57, this got the reaction they expected from Gardner residents. HSR say they are not going forward with these 5-track at-grade alignments.jpk122shttps://www.blogger.com/profile/15793230015467656460noreply@blogger.comtag:blogger.com,1999:blog-8419444332771213285.post-82511839803267105132017-08-14T17:55:17.934-07:002017-08-14T17:55:17.934-07:00Eventually, he found out that hovercraft are never...Eventually, he found out that hovercraft are never going to be more than a niche application. last I heard they are reinventing things proposed back in the 50s and 60s with the maglev PRT in tubes.

Here is a <a href="http://www.hsr.ca.gov/docs/programs/statewide_rail/proj_sections/SanJose_Merced/San_Jose_CWG_PPT_080217.pdf" rel="nofollow">direct link</a>. Slide 33 is the key slide, although it's barely legible and the original full-resolution map does not seem to have been made available. <br /><br />The at-grade alternative is clearly being sand bagged here. Do not cross two train flows as they approach SJ from the North; keep ACE and Amtrak on the east side, and Caltrain HSR on the west side, and never the two shall conflict. Make Caltrain and HSR share platforms just like at SF Transbay. Make UPRR blend under the wire; there is no technical reason they can't do <a href="http://www.railpictures.net/photo/239947/" rel="nofollow">what CSX does every day</a>, even with double stack container freight. Three tracks through Gardner, all of them electrified, are probably sufficient. UPRR may hem and haw, but money talks in Omaha. I have other thoughts that will probably be worth another post at some point. One thing is exceedingly clear: nobody is even trying to make the at-grade option work properly. Where is the City of San Jose to knock some sense into this circus?Clemhttps://www.blogger.com/profile/01374282217135682245noreply@blogger.com
