Act of Parliament. The LSWR objected to the arrangement as well, fearing that there would be insufficient accommodation for their own trains at Weymouth station. A request by the Weymouth and Portland company that its line might be operated by GWR broad gauge trains only was objected to by the Board of Trade: the line was authorised as a mixed gauge operation. The issue was now put to arbitration under Captain Galton. He adjudicated that the Weymouth & Portland company could use Weymouth GWR station and pay them £2,600 for the accommodation provided, and £3,175 for land and works arranged by the GWR at the junction. Open to traffic In September 1865 an agreement was finally settled, and early in October the Board of Trade approved the working arrangements. So far as the propelling from Weymouth was concerned, the resolution appears to have been that the train engine ran round at Weymouth Junction, hauling its train to and from that point. Goods traffic started working on 9 October, and on 16 October 1865 passenger trains started running. The first day's receipts amounted to £26. Eleven trains ran each way except Sundays when four operated. After a few weeks this was reduced to eight and three respectively. The passenger service was run entirely by the LSWR at first, and this continued for some considerable time. The GWR worked the goods traffic, although occasionally narrow (standard) gauge goods wagons were attached to LSWR passenger trains. A new station at Rodwell was opened on 1 June 1870. The signals at Portland were of the Stevens Patent lattice type, but at Weymouth Junction they were of the GWR disc and crossbar type. The Great Western Railway route at Weymouth was converted to narrow (standard) gauge between 18 and 22 June 1874, of course affecting the Portland line also. Portland harbour breakwater and Admiralty line In the 1840s it was desired to provide a harbour of refuge at Portland. There was no other suitable place between Portsmouth and Plymouth. On 11 May 1847 an enabling Act was passed; the Commissioners of Woods and Forests could acquire land necessary to build a breakwater. Construction of the breakwater was a prodigious task involving very large quantities of stone and gravel, and it was not completed until 1872. Even then much further defensive and marine work was continuing. During the construction of the breakwater, a number of temporary
