Photos - 1972 Tube Stock Drivers' Cabs
Fig. 1: Original 1972 Tube Stock Control
Desk
 Interior of 1972
Tube Stock cab showing the nearly original condition before conversion to OPO and
refurbishment. A number of Mk I trains reamined in this condition until they were
all withdrawn from the Northern Line and replaced by the 1995 Tube Stock.
The control desk is very similar to that of
the C Stock. The controls on the window pillar are for (top) Rate Switch, Overloads
and MG set and trip and Window Wiper. The microphone was added for train radio.
This photo was taken in the cab of a unit
stored at Hainault (Central Line) where some trains were stored after withdrawal from
passenger service.

Tube Stock Mk I - Original Offside Console
The original offside console of the 1972 Mk I
Stock. The only modification has been the insertion of the red Tripcock Reset push
button. Originally, tripcocks were reset manually from outside the cab but,
following a number of incidents when drivers slipped whilst climbing around the front of
the train to reset, the operation was converted to a remote action, activated by the push
button.
The red handle is the offside emergency brake
valve. This is connected to the brake pipe to apply the brakes when operated.
This was originally provided for use under automatic train operation but ATO was
never provided on this stock.
In the cabinet below the desk is the traction
control fault isolation switch, the automatic coupler controls, and main and train line
isolating cocks for emergency use. Photo by Tube Troll.

1972 Tube Stock - Refurbished Drivers Desk
The refurbished driver's desk of the 1972
Stock. The main alteration is the addition of door control buttons along the edge
of the desk. There is also a whistle lever in place of the button usually used
on LUL. Additional controls have been added to the window pillar for passenger
alarm response. Photo by Tube Troll.
