I called London Transport Info Line and they told me that last train
from Oxford Circus will leave for Brixton at 10.17pm, for Walthamstow
at 10.23pm. The posters are vague. No information about a rail
replacement bus (!) either.

Information about Engineering Works is appallingly vague and causes a
lot of frustration for staff.
