Knowsley Park, seat of the Earl of Derby, appears on the N. The mansion has evidently been erected at different periods; its most ancient part is of stone, and is said to have been raised by the first Earl of Derby, for the reception of his son-in-law, King Henry VII., in whose honours the Earl had been mainly instrumental. Great enlargement and decoration of the mansion took place on occasion of this royal visit: a handsome stone bridge was thrown across the Mersey at Warrington, and an embankment or causeway thrown up across the marshes to the rising ground on the Cheshire side. Many valuable and interesting pictures adorn the mansion, which is surrounded by a beautiful park. Several coal, lime, and marble works are passed on either side; and while traversing the Huyton embankment, Preston church, the Hazels, seat of Joseph Birch, Esq., and the church and village of Huyton are observed on the N. On the S. appears Childwall park, hall, and church; beyond, is Woolton hall, seat of N. Ashton, Esq.; the whole scene finely wooded. Huyton Gate and Roby-lane Gate Stations are shortly passed; the village of Roby lies S. of the line, and closely adjoining it. Proceeding onwards, along a pleasant but not very interesting part, Summer-hill house is seen, the seat of Thomas Case, Esq.; also, the little church of Notting Ash and Childwall hall, a seat of the Marquis of Salisbury. Broad Green Station. A FEW yards from the station, on the N. side, is a place for the landing of cattle, sheep, &c. The line now enters the Olive Mount excavation, which is an immense chasm, cut in the solid rock, to the depth of from 50 to 70 feet, the precipitous rock forming a grand wall on either side. The village of Wavertree lies S. of the line, after emerging from the Olive Mount ravine; Spekelands, the residence of Mrs. Earle, lies also on the S., and on the N. is the residence of C. Lawrence, Esq. Here the Liverpool tunnels commence; one, for conveying passengers, &c., into the Company’s station-yard in Lime-street, turns off on the right hand, and is 2,230 yards long, 25 feet wide, and 17 feet high. The other, for the conveyance of goods, direct to the docks, in a straighter continuation of the line, is 2,250 yards long, 22 feet wide, and 16 feet high. Engines are stationed on each side of the line at this part, each of forty-horse power, to draw the trains up the inclined plane of the tunnel, in coming out of Liverpool, and let them down on their arrival from Birmingham. The locomotive engines being attached to and detached from the trains at this station. * * * * * “A Friend to Railways,” in a letter to the Editor of the Railway Magazine, May 1838, thus describes the mode of drawing the trains up the inclined plane:—
