Was trying to look up Dupont Circle's depth, but instead happened upon this article from 1998 about Metro escalator woes:
Escalator Troubles Rooted In Metro's Original Design

Definitely an interesting blast from the past, there...

Was trying to look up Dupont Circle's depth, . . .
Inventory of stations with escalators over 45' 13.71m vertical rise.
A Route Red Line
Dupont Circle
3 escalators north end surface to mezzanine
94' 5 3/4" 28.79m
3 escalators south end surface to mezzanine
84' 9 1/4" 25.83m
Woodley Zoo Park
3 escalators intermediate level to mezzanine
103' 2 1/2" 31.45m
Cleveland Park
3 escalators intermediate level to mezzanine
58' 9 3/8" 17.92m
Van Ness
3 escalators intermediate level to mezzanine
56' 6 1/8"
17.30m
Tenleytown
3 escalators intermediate level to mezzanine
81' 3 1/2" 24.76m
Friendship Heights
3 escalators intermediate level to mezzanine
65' 10 3/4" 20.08m
Bethesda

C Route Blue Yellow Lines
Pentagon *
3 escalators from Pentagon Concourse to mezzanine
59' 3/4" 18.00m
K Route Orange Line
Court House **
3 escalators intermediate level to mezzanine
48' 6 1/4" 14.76m
All Stations in deep rock except Court House and Pentagon.
* Station in cut and cover. Escalators no longer in service
** Deepest station in cut and cover
I compiled most of the data from field measurements I made in the months prior to the closing of the direct entrance into the Pentagon.
Congress Heights and Huntington may also have escalators with vertical rises greater then 45' 13.71m, one day I might do field measurements to confirm it.
