You can park here quickly, or just take the stairs. Coordinates are not exact. Cache is within 5 meters of the center point. To find cache, find hints in this really bad poem (oh, and in the pictures):
High above the level of man,
One can smell herbs of the land,
Twice you must ascend,
To find the hidden gem.
There is a sight you must take in,
Trains convey us to destinations,
Or our origin?
Only sky above,
Metal below,
Numbers rule the cosmos,
Follow them to the point,
And you will find what you seek,
Maybe even a train you can peek.
