• What is the (expected future?) train frequency on Caltrain?

• If only two platforms are for departing trains, that means that just to support 8 tph, maximum platform waiting time is 15, not 30 minutes. (For 12 tph, just 10 minutes.)

• (Sidenote: a 15 minute period at each departure platform allows for a 40-45-minute train turnaround with uniform 15-minute cycles at each of two arrival, tail, and departure tracks. A 10 minute period at departure platforms would require four tail tracks operating in a - perhaps more realistic - 20-minute cycle.)

• I must ask, what is the planned curve radius? For, curved platforms even where you have cars is not at all unheard of, so I am not sure why they require straight platforms. (Below: Cologne main station, and my own photo at Le Mans)

* Those tail tracks must be pretty long already to accomodate 400m trains. Has no genius considered a loop-back through station, at least for the Caltrain part?
