This rotary control shaft (above) was used to operate the mechanism
to lock  the  closed  swing  shaft  in  place  with  the  railway  track
properly  aligned  so that trains could  safely  cross  the bridge.
This mechanism, which must be engaged and locked before
a train can be driven across the swing span, ensures the
vertical and horizontal alignment of the running rails
at both ends of the swing span.
