A single line of way was completed over Chat Moss by the 1st of January, 1830; and on that day, the “Rocket” with a carriage full of directors, engineers, and their friends, passed along the greater part of the road between Liverpool and Manchester. Mr. Stephenson continued to direct his close attention to the improvement of the details of the locomotive, every successive trial of which proved more satisfactory. In this department he had the benefit of the able and unremitting assistance of his son, who, in the workshops at Newcastle, directly superintended the construction of the new engines required for the public working of the railway. He did not by any means rest satisfied with the success, decided though it was, which had been achieved by the “Rocket.” He regarded it but in the light of a successful experiment; and every succeeding engine placed upon the railway exhibited some improvement on its predecessors. The arrangement of the parts, and the weight and proportions of the engines, were altered, as the experience of each successive day, or week, or month, suggested; and it was soon found that the performances of the “Rocket” on the day of trial had been greatly within the powers of the locomotive. The first entire trip between Liverpool and Manchester was performed on the 14th of June, 1830, on the occasion of a Board meeting being held at the latter town. The train was on this occasion drawn by the “Arrow,” one of the new locomotives, in which the most recent improvements had been adopted. Mr. Stephenson himself drove the engine, and Captain Scoresby, the circumpolar navigator, stood beside him on the foot-plate, and minuted the speed of the train. A great concourse of people assembled at both termini, as well as along the line, to witness the novel spectacle of a train of carriages dragged by an engine at a speed of 17 miles an hour. On the return journey to Liverpool in the evening, the “Arrow” crossed Chat Moss at a speed of nearly 27 miles an hour, reaching its destination in about an hour and a half.
