progress. The trend is to consolidate and modernize yards which are adequate for present needs.
The approximately 3,100 railroad bridges have an aggregate length of over 30 miles and generally are of steel-girder and reinforced-concrete construction. The longest, the Arsta Bridge, a 2,500-foot double-track steel structure with an arched-stool span and reinforced-concrete arches, crosses the Arstaviken (lake) just south of Stockholm.
The 78 tunnels have an aggregate length of 11 miles. Many are cut through massive granite and gneiss formations and do not require lining. Tunnels on electrified sections, however, are generally lined with concrete to reduce seepage. Most tunnels on double-track lines are also double track. The recently completed 1.3-mile tunnel at Garda near Goteborg on the Almedal-Boras line is now the longest in the system. The plan to link Sweden to Denmark by rail tunnel has been indefinitely postponed. In the north are numerous snowsheds and avalanche galleries.
Rail ferries are very important links with other Scandinavian countries and the rest of Europe and very important transporters of international traffic. The SJ operates five ferries: the Trelleborg (capacity 34 two-axle freight cars), the Skane (capacity 39), the Starke (capacity 21), and the Drottningen (capacity 20) connect Trelleborg and Sassnitz, East Germany. The Drottningen also links Trelleborg with Travenmunde, West Germany, and Stockholm with Naantali, Finland. The Malobus (capacity 12 two-axle freight cars) connects Malmo with Copenhagen, Denmark. It is planned to add large new ferries to the Sassnitz and Naantali routes. Denmark and East Germany also operate rail ferries to Sweden.
Automatic block signaling has been installed on most lines. Centralized traffic control (CTC) is in use on 1,179 miles. Most CTC is found on the heavily trafficked lines in the southern and central portions of the country and on the Lulea-Narvik line in the north. Plans call for 1,800 miles of CTC operated from 10 control centers. Administrative centers are linked by an automatic telephone network. A selective telephone network connects the stations, most of which have telegraph. Because of the great demand for complete data at all levels of operation, the teleprinter network now has over 400 terminals. In the past, radiocommunications was used chiefly in yard operations. Full-scale tests of radiocommunication have been made on the Kiruna-Riksgransen line to link stations, trains, and repair and maintenance
