National
Rail


is
warning
that
failures
affecting
computer
systems
are
disrupting
train
services
this
morning,
particularly
on
Govia
Thameslink
Railway,
although
other
operators
are
also
reporting
problems.

Passengers
are
being
warned
that
problems
in
retrieving
driver
diagrams,
which
are
the
details
of
duties,
routes
and
timetables
for
individual
drivers,
mean
that
some
trains
cannot
run,
while
real
time
information
displays
are
also
faulty.

The
failures
are
part
of
a
much
wider
series
of
faults
which
is
affecting
banks
and
airlines
around
the
world,
including
Australia,
Japan,
India
and
the
USA.

In
Britain
medical
appointment
services
are
also
affected.

Microsoft
is
reported
to
be
using
‘mitigation
measures’,
but
the
cause
of
the
problems
is
not
yet
clear.
