Definition of "recasting"

But for the tragedy of the war, which has compelled a recasting of train services, it was the intention of the Belgian National Railways, Mr. L. Wiener writes, not only to have retained in service throughout the winter one in each direction daily of the Brussels-Ostend streamline trains, […] but also to introduce similar services between Brussels and Liége.
