At street level the trains drew their power from the trolley wire overhead -- on the "L" structure from a third rail. This is the last station before this eastbound train mounts the "L" structure. Above the old station, up on the embankment, is the nearly completed new station.
The elimination of trolley pole running on the western end of the Lake Street "L" allowed the CTA to modernize its fleet without the cost of trolley poles. See the CTA cars in Photo 1.
