Red line station depth

[YOLO]

Is there a list of how deep every underground Red line stations are?

Is there a list of how deep every underground Red line stations are?

To my knowledge no. The only thing close would be my list of stations with escalators over 45' 13.71m vertical rise.

A Route Red Line

Dupont Circle
3 escalators north end surface to in train hall mezzanine.
94’ 5 3/4"
28.79m
3 escalators south end surface to in train hall mezzanine.
84’ 9 1/4"
25.83m

Woodley Zoo Park
3 escalators intermediate level below surface to in train hall mezzanine.
103' 2 1/2"
31.45m

Cleveland Park
3 escalators intermediate level below surface to in train hall mezzanine.
58' 9 3/8"
17.92m

Van Ness
3 escalators intermediate level below surface to in train hall mezzanine.
56' 6 1/8"
17.30m

Tenleytown
3 escalators intermediate level below surface to in train hall mezzanine.
81' 3 1/2"
24.76m

Friendship Heights
3 escalators intermediate level below surface to in train hall mezzanine.
65' 10 3/4
20.08m

Bethesda
3 escalators intermediate level below surface to in train hall mezzanine.
107' 6 1/2"
32.77m

Medical Center
3 escalators surface toin train hall mezzanine.
100' 11 7/8"
30.78m

B Route Red Line

Wheaton
3 escalators from surface mezzanine to platform.
115' 5"
35.17m


C Route Blue Orange Lines
Rosslyn
4 escalators from surface mezzanine to platform.
97' 9 1/4"
29.80m

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 below surface to in train hall mezzanine.
48' 6 1/4"
14.76m

All Stations in deep rock except Court House and Pentagon.
* Station in cut and cover.
** Deepest station in cut and cover.

The way I compiled the list:
I visited each station with a measuring tape, measured the riser heights in the transition at the top and bottom of an out of service escalator, counted the remainder of the risers in the escalator, multiplied the number of risers by the riser height and added that to the transition riser heights.

It easier in stations with stairs, measure riser height between landings, multiply by total number of risers by the riser height[s].

Add 40" for distance from platform to top of rail.

The accuracy of the total depth measurement should be withing 18" as all stations in subway are on a grade of 0.35% for drainage, the down hill end of the station is 24 1/4" lower then the up hill end of the station.

That won't work for the deepest: Forest Glen...

The only station for sure that I know the depth of is Forest Glen, which has the tracks 196 ft (21 stories) underground. It's the only station where escalators couldn't be used due to the depth and also has a special track fire suppression system.

Besides that, I remember that Congress Heights is either the deepest or one of the deepest cut and cover stations when that opened with the Branch Ave extension.

I think Court House is deeper. Never measured the surface entrance vertical rise at Congress Heights, at Court House one descends to a level below the street before descend to the mezzanine. The combined vertical rise at Court House is greater then the vertical rise at Congress Heights.
