Subterranean Premises for a Telephone Exchange in BUDAPEST
(1951 - 1954)
1. The Underground Railway Planning Office, BUDA EST, which was asp"
cially formed for the purpose, began in 1951 to plan the construction of a
subterranean telephone exchane to adjoin the underground station "Perenc
DEAK Place" in BUDAPEST.
2. In 1952, the project, handled by Dr. Karoly SZ.ECHI, chief engineer
and director of the Underground Railway Planning Off ice had passed the plan-
ning stage, and actual work under the control and supervision of a Soviet
engineer commenced. The task was finished two years later.
3. The construction of the premises to accommodate a telephone exchange
was not easy as the shelter on its SE side was only a few metres away from
the foundations of a five-storey building, occupied by the Ministry of the
Interior; and on the NE side there was a high church. (In fact the work
caused the church to sink only 4.. mms.).
4. The underground premises, two metres below street level, had a mantle
and curling of 2.5 metres of reinforced and a reinforced concrete floor of
1.2 metres in thickness. Internal dimensions of the shelter were as
follows:
Length
approx.

staircase), and one for the telephone exchange proper, (on the floor above,
but covering only half the width of the shelter. (See Sketches 1$2,3-)
A door on either side of the escalator of the Underground Station
gave access to a covered passage, asout seven metres long, which led to the
shelter from which one door led to the telephone exchange and one to the
machinery floor.
6. Only the bare shelter was built with all necessary electrical and
plumbing leads, to enable switchboard panels, water supply, heating and
usual shelter machinery, to be installed later.
7. The shelter had one air vent loading to street level near the en-
trance to the underground station, and. one on the roof of the Ministry of
the Interior.
8. When construction of the shelter was finished, the doors on either
side of the escalator c:.,uld be seen for some months afterwards. They
were subsequently bricked up and have been so ever since.
