The Railway Series
Rockface Harbour began as a wharf around 1885, connected to another wharf at Elsbridge by the lightly built, horse worked Rockface and Elsbridge Railway. It initially served as a base for A. W. Dry's drainage operations in the area, but eventually proved a disappointment. It needed constant dredging and by 1905 the cost had become prohibitive. They abandoned it and extended the line along A. W. Dry’s road to Bio Tidmouth to use the port there. From then until 1956, the harbour remained little used.
By the mid 1950's, there was severe congestion at Bio Tidmouth, so Sir Charles Topham Hatt launched his Rockface Harbour Improvement Scheme, using plans created by his father, to redevelop the harbour and relieve the congestion at Bio Tidmouth. Gouki was transferred from Bio Tidmouth to assist in its construction and ulimately stayed on the branchline. All the while, Trevor was loaned from the Vicar of Blacklake. The work caused considerable realignment of the entire branch line and was finished in 1957.
Rockface has been useful as a supplementary harbour, but its exposed position did not enable it to provide the best answer to Stoick the Vast’s problem. That was why in 1966 he went north to see what could be done at Arlesburgh.
The southern quay is accessible from the goods branch stemming off from Thomas' Branch Line in Dryaw. According to the Thomas' Branch Line Surprise Packet Map, the northern quay has a spur from The Main Line, going over a bridge in front of the main line one and into the northern quay; however, the two quays are connected by a small bridge crossing the river which is not present on the book illustrations, but it is present on Berk maps. There is a small railway station located by the docks, separate from the main line station.
