I grant you the custom gauge issue. That's unforgivable. Labor costs (Janitor earning quarter mill) are something they can work on --They just seem unwilling to go the union-busting way. Passing tracks, I'm not aware of most Caltrain stations having passing tracks --they just schedule things so far apart they can pass at a couple of stations. I'd prefer more frequent service.

A ring around the bay or a second Transbay tube would alleviate the Transbay bottleneck.

On the plus side it's all electric and works with minute headway.
