The Surrey Iron Rail-way was also a landmark in railway history because, although in itself of very small extent, it was originally designed to serve as the first section of a railway which, made by different companies, as capital could be raised, would eventually have extended from the Thames to Portsmouth.[37] The second section was the Croydon, Merstham and Godstone Iron Railway, which Parliament sanctioned in 1803. From Croydon this further railway was to carry the lines on to Reigate, with a branch from Merstham to Godstone Green, a total distance of sixteen miles in addition, that is, to the nine and a half miles of the Surrey Iron Rail-way. Both companies, however, drifted into financial difficulties, and had to apply to Parliament again, in 1806, for fresh powers, while the lines of the second company never got beyond the chalk quarries at Merstham. In the absence of the through traffic it had been hoped eventually to secure, the local business alone available was evidently inadequate to meet the charges on a capital outlay which, at that time, may have been regarded as not inconsiderable, inasmuch as the Surrey Iron Rail-way attained to a good elevation at its southern end, while the Croydon, Merstham and Godstone line went through a cutting thirty feet deep, and crossed a valley by an embankment twenty feet high. After a chequered career, the Merstham line was acquired by the Brighton Railway Company in 1838 and closed, being then no longer required. The Surrey line lingered on till 1846, when, with the sanction of Parliament, its operation was discontinued, the rails being taken up and sold by auction. {225}It was unfortunate that these two pioneer public railways were a failure because, had they succeeded, and had they really formed the first sections of a through line of communication between the Thames and Portsmouth, there would have been established a further precedent--and one of much greater value than that of a common user--the precedent, namely, of a trunk line made by companies co-operating with one another to give continuous communication on a well-organised system, in place of collections of disconnected lines designed, at the outset, to serve the interests only of particular localities, with little or no attempt at co-ordination. Yet the principle of a general public railway had, at least, been established by the Surrey and Merstham lines, and this principle underwent further important development by the Stockton and Darlington Railway, the first Act for which was obtained in 1821.
