 When judgment in Chancery was found against the LNWR, it refused to open the line to the S&BR, stating that it would be unsafe, as certain safety undertakings had not been formalised by the S&BR.The latter company then announced its intention of running a train anyway, on 1 December 1851.However the running powers held by the S&BR were for the Stour Valley line, which did not include entry to New Street station, which was part of a separate construction, and the LNWR physically obstructed the running of the train.
