Within Center City, where there is a higher concentration of destinations, the stops were spaced closer together as hammer mentioned. Outside of Center City, they're farther apart. Older systems tend to have much tighter spacing (the Paris Metro has some short station distances). Newer systems - DC Metro, BART - which were built as more regional systems have longer spacing.

Thanks for the information. But In all honesty, is there really a need to have an 11th street and 13street? You can walk there.
