The tramway terminus at Purley Corner is now a busy place. Those are only the "old crocks" who can remember the South Eastern railway-station of Caterham Junction and the surrounding lonely downs; and to them the change to "Purley" and the appearance in the wilderness of a mushroom town, with its parade of brilliantly lighted shops, its Queen Victoria memorial, its public garden and penny-squirt fountain, and--not least--its hideous waterworks, are things for wonderment. "How strange it seems, and new," as Browning--not writing of Purley--remarks. Even the ghastly loneliness of the long straight road ascending the pass of Smitham Bottom is no more, for little villas, with dank little dungeons of gardens, line the way, and tradesmen's carts calling for orders compete with the motorists who shall kill and maim most travellers along the highway. The numerous railway-bridges, embankments, cuttings, and retaining-walls that disfigure the crest of Smitham Bottom are chiefly the results of latter-day activities. The first bridge is that of the Chipstead Valley Railway--now merged in the South Eastern and Chatham--from South Croydon to Chipstead and Epsom, 1897-1900, with its wayside station of "Smitham." This is immediately followed by the London, Brighton, and South Coast's station of Stoat's Nest, a transformed and transported version of the old station of the same name some distance off, and beyond it are the bridges and embankments of the same company's works of 1896-8; themselves almost inextricably confused, to the non-technical mind, with the adjoining South Eastern roadside station of Coulsdon. The chapters of railway history which produced all this unlovely medley of engineering works are in themselves extremely interesting, and have an additional interest to those who trace the story of the Brighton Road, for they are concerned with the solution of the old problem which faced the coach proprietors--how best and quickest to reach Brighton. [Sidenote: RAILWAY POLITICS] Few outside those intimately concerned with railway politics know that although the Brighton line was opened throughout in 1842, it was not until 1898 that the company owned an uninterrupted route between London and Brighton. The explanation of that singular condition of affairs is found in the curious reluctance of Parliament, two generations ago, to give any one railway company the sole control of any particular route. Few in those times thought the increase of population, and still more the increase of travelling, would be so great that competitive railways would be established to many places; and thus to sanction the making of a railway to be owned by one company throughout seemed like the granting of a perpetual monopoly.
