lighting used for the first time in any subway
provides excellent illumination. Escalators of re-
versible type connect the mezzanine floors with
the train platforms. Extra wide train platforms
assure freedom of movement. In the downtown
area the center platform is 3500 feet long, ex-
tending across the entire loop from north to
south. Entrances to stores and shops from the
Mezzanine floors will be greatly appreciated by
patrons of the subway and prove a great time
saver.
