   “The "D.N.B." wrote of one Railway Member that "he made himself personally acquainted with the working of the new systems of railroads, and with more foresight than his neighbours, he welcomed railways on his estate when other landowners were ordering their gamekeepers to warn off the surveyors or to put an end to their operations by force."”
