Los Angeles Times, 10/20:
 

State rail authority reduces size of future bullet train stations

 

The California bullet train authority has told its design engineers that the future system would have shorter trains and smaller station platforms, reducing the capacity of individual trains by roughly 50% and potentially the capacity of the entire Los Angeles-to-San Francisco route.

 

It is the second time that operating parameters have been reduced this year.

 

In May, the authority’s managers decided to cut the maximum operating speed of trains inside tunnels from 220 mph to 200 mph, a result of building tunnels with smaller cross-sections. The authority also cut in half the speed of trains as they merge from station tracks onto the system’s main line, a move that would reduce the very long lengths of transition tracks in and around major cities.

The switch to shorter trains was disclosed in a Sept. 7 memo that outlined reductions in the size of future passenger platforms, based on a decision that the high-speed rail system would operate trains of only 10 cars. The previous plan was to operate a “double” train set, which could have up to 20 cars.

High-Speed Rail Route to L.A. Coming Into View You wouldn’t know it by the scant media coverage, but construction of the state’s bullet train is in full swing around Fresno and the Central Valley. The California High-Speed Rail Authority will likely next build out the northern stretch—to Silicon Valley and San Francisco—but its narrowing in on how to get to Los Angeles and what that route will look like.
