This four-coach train, which included a restaurant car and typewriting facilities, ran between Broad Street [London], Coventry, Birmingham and Wolverhampton, and was put on in February, 1910, as a counterblast to the improved service to Birmingham which the G.W.R. was to introduce with the opening of the shortened route via Bicester.
