A small container is hidden near the train station. In order to
find it, you will have to find its coordinates hidden in the
station. There are four distinct groups of public pay telephones in
the station. The coordinates are hidden on one of these phones. The
hint gives the telephone number where the coordinates are hidden.
Your search will be easier if you know what a comfort station is.
After you find the coordinates, exit the station on the 29th
Street side for a short walk to the cache.
From the 30th Street Station web site:
30th Street Station, a National Register of Historic Places, is
an eight-story concrete frame building containing approximately
562,000 gross square feet. Built in 1934, this stately landmark is
the home of the corporate offices for Amtrak, the Station Market
retail space, and the largest existing and second most active
railway station in America. Located on Market Street between 29th
and 30th Streets, in Philadelphia, Pennsylvania, the site around
the Station is an entirely elevated "bridge" type structure which
includes Market, Arch, and 30th Street, and Schuylkill Avenue.
The overall building size is 700 feet long and 325 feet wide,
covering almost two city blocks.
