Sorry, but ordering trains to drive manually after the system locks itself down, is the proper procedure. Of course you are still supposed to only send trains to free sections, but the error is in that step, not that they ordered a train to drive on it's own.
Also the fallback procedure is also aided by automatic systems and a sizable number of accidents in the past were caused by that information being faulty.
