Or getting off the Central Subway to get onto Caltrain and seeing this?
Perhaps you are headed downtown, and need to get across King Street to the station and you see this...
Station placement is very important for lines like the Central Subway. Otherwise you end up 20 years from now reading something like this - the answer to which would be "8 billion dollars or a time machine".
Moving the station to in front of the Caltrain station would make this line hum, and remove the tempation - succumbed to by hundreds of patrons daily - to jaywalk across King Street at 4th, which is also known as "The onramp to I-280 Southbound".
This can be coupled with eliminating the planned Brannan Street station, saving money and reducing the overall number of stations on the line. This is a lesson that was learned the hard way by Santa Clara VTA
