Going eastbound, Laramie is the first station above Lake Street; the line follows an elevated embankment to Harlem/Lake and transitions from an elevated structure to the embankment immediately to the west of the station.
This passage describes the route of a train line that starts at Laramie and travels eastward, passing over Lake Street before ascending an embankment to reach Harlem/Lake. The track then changes elevation again as it moves west of the station.
