Hello DEEDON68
Thanks for your nostalgia history -- I figured you likely lived along, grew up along that line. Glad to find someone who has a more personal interest in the old Myrt.
OK, if you look at the 1940's photos of the BOTH SIDES of the Vanderbilt Station I previously provided, as it was originally built in the 1880's. the both sides of the station house proper had FOUR windows, and ONE window in the top of stairs "vestibule room" outside the station house proper.
As part of a late 1950's upgrade on the Myrtle El, and arrival of overhauled Q-Type EL (MUDC class) cars to replace the older open end platform 1300 series gate motor cars, the station houses were "modernized" in the upgrade with new simplified exterior sheathing - eliminating the more intricate woodwork details.
As far as Vanderbilt Station goes,
---the Downtown side wall of the "house" had only THREE of the 4 windows retained --- the 4th one closest to the stairway entry end - was removed and sheathed over. That was the side the station token agent was on, and he had one of the windows for his booth.
---the Uptown side wall of the "house" had TWO of the 4 windows retained --- the other two closest to the stairway entry end, were removed and sheathed over.
The station stairway top-vestibule enclosure still retained its original ONE window on both sides.
I have attached 1 photo of the UPTOWN and two of the DOWNTOWN side of that station per 9-1969
Also one more photo looking downtown to the El and a downtown train having just left the Vanderbilt Ave Station, Sept. 1969
