Holyhead is the terminus of this extraordinary line—a line of great value to this place, effecting as it has done a rapid communication between this port and the eastern part of the county, as well as the manufacturing districts of Cheshire, Lancashire, and the North; while, uniting with other lines, a connexion is opened up with the Metropolis. RAILWAY STATION. The Holyhead Station is an extensive and commodious one, connected with which are Refreshment Rooms, with Waiting and Dressing Rooms attached, Telegraph Office and a well furnished Book Room, the whole fitted up on a most splendid scale, well arranged and in excellent order, and plentifully supplied with luxurious food. A table d’hote at the Refreshment Rooms on the arrival of the mail and express packets from Ireland, conducted by Mrs. Hibbert, late of Wolverton. In Mr. Massinberd, manager of the Railway Station, the traveller will meet with a gentleman anxious to give every information which even the most timorous and querulous may require to further his views, or quell his fears. The Railway Company have also erected a large cattle and luggage station on the pier. A new line of railroad has been constructed along the margin of the _traeth_, or sandy estuary, which forms the Harbour, extending nearly a mile from the Station to the Pier. Arrangements for the transit of goods and live stock between Ireland and England have been made. A steamer leaves the North Wall, Dublin, every evening; but the period has been so short that no opportunity has been afforded to ascertain its success; there is, however, every prospect of the traffic becoming a very important feature in the developement of this line, and certain to be productive of a large additional revenue to the company. There are many distinguished men in the railway world, who have been accustomed for many years to look _afore_ and _aft_, who do not despair of seeing the Chester and Holyhead one of the most profitable, as it is one of the best officered, lines of railway in the kingdom; but we think that the government should take upon itself to cover the vast outlay which it caused in the erection of that wonder of the world, the Britannia Tubular Bridge—a NATIONAL CONVENIENCE.
