Because they have 3+2 seating. Nobody likes 3+2 seating except the purchasing agents.
I'm sure we could come up with something more innovative after all these years?
Well the multi-levels and BBD cars require two trips of the conductor through each car, which is not easy during frequent stops. They also place the engineer much closer to street level in case of grade crossing accidents. There is a solid argument to be made that the gallery car is more innovative than the following series of cars.

Also sometimes innovation hits a dead end and that's not a bad thing. Do we really need a lot of new ideas? Or do we need a fleet of cars that will last for 40 years without rusting or causing problems?
The AK-47 is also incredibly durable, simple, and easy to repair, but somehow I don't see the US Military using them.
If you study your history, there is a lot of controversy about the M16 procurement process. I would not use the M16 v AK47 as a benchmark for best practices in government procurement. In fact the M16 procurement has all sort of documentaries written about the problems and hiccups.
Siemens cars (and Amtrak does a poor job maintaining them)


I love the completely unnecessary and irrelevant dig at Amtrak though.
Amtrak's failure to maintain their equipment and the Siemens equipment's failure to perform in cold weather is cold hard documented fact. You are welcome to your own opinion but not your own facts.
screech machines

IS this a technical term? It's really hard to have a discussion with people who use terms like "screech machines" and deny the documented evidence and facts.

Trains News Wire is reporting the full section between SF and San Jose has been energized.

Fair Use:
Caltrain’s entire 51-mile electrification corridor between San Francisco and San Jose, Calif., has been successfully energized and tested for the first time, the commuter rail agency has announced. The milestone in the project by Caltrain, power company Pacific Gas & Electric and contractor Balfour Beatty enables full-speed testing of the electric trainsets along the entire corridor in preparation for electrified revenue service in September.

Wonder who will try to steal the live wire? It will be interesting to find out how much the base load with no cars operating or connected to live wire. I would think that Caltrain will keep data on each train set connected to CAT to find any stealing of electricity?

That's 25 thousand volts ac they would be stealing. You would need a step down transformer to lower the voltage to a usable level, and transformers are relatively easy to see.
