The Bern–Lötschberg–Simplon railway (BLS), known between 1997 and 2006 as the BLS Lötschbergbahn, was a Swiss railway company. In 2006 the company merged with Regionalverkehr Mittelland AG to form a new company called BLS AG.
The Tinkertoy Construction Set is a toy construction set for children. It was created in 1914—six years after the Frank Hornby's Meccano sets—by Charles H. Pajeau, who formed the Toy Tinker Company in Evanston, Illinois to manufacture them. Pajeau, a stonemason, designed the toy after seeing children play with sticks and empty spools of thread. Pajeau partnered with Robert Pettit and Gordon Tinker to market a toy that would allow and inspire children to use their imaginations. After an initially slow start, over a million were sold.
The New Railway Link through the Alps (NRLA), is a Swiss construction project for faster north-south rail links across the Swiss Alps. It includes base tunnels several hundred metres below the existing apex tunnels along two axes, the Gotthard and the Lötschberg. The 57-kilometre (35 mi) Gotthard Base Tunnel and the 35-kilometre (22 mi) Lötschberg Base Tunnel are the respective centers of those two axes. Swiss Federal Railways subsidiary AlpTransit Gotthard AG and BLS AG subsidiary BLS Alp Transit AG were founded for this project and built the tunnels.
The Blue Ridge Railroad was incorporated by the Commonwealth of Virginia in March 1849 to provide a state-financed crossing of the Blue Ridge Mountains for the Virginia Central Railroad, which it became a part of after completion.
The Blue Ridge Tunnel is a historic railroad tunnel built during the construction of the Blue Ridge Railroad in the 1850s. The tunnel was the westernmost and longest of four tunnels engineered by Claudius Crozet to cross the Blue Ridge Mountains at Rockfish Gap in central Virginia.
The Lötschberg Base Tunnel (LBT) is a 34.57 km (21.48 mi) railway base tunnel on the BLS AG's Lötschberg line cutting through the Bernese Alps of Switzerland some 400 m (1,300 ft) below the existing Lötschberg Tunnel. It runs between Frutigen, Berne, and Raron, Valais.
Blue Mountain, Blue Mountain Ridge, or the Blue Mountains of Pennsylvania is a ridge of the Appalachian Mountains in the U.S. state of Pennsylvania. Forming the southern and eastern edge of the Ridge-and-Valley Appalachians physiographic province in Pennsylvania, Blue Mountain extends 150 miles (240 km) from the Delaware Water Gap on the New Jersey border in the east to Big Gap in Franklin County, south-central Pennsylvania, at its southwestern end.
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.
The Lötschberg Tunnel is a 14.612 km (9.079 mi) long railway tunnel on the Lötschberg Line, which connects Spiez and Brig at the northern end of the Simplon Tunnel cutting through the Bernese Alps of Switzerland. Its ends are at the towns of Kandersteg in the canton of Berne and Goppenstein in the canton of Valais. The top elevation of the tunnel is 1,240 m (4,070 ft) above sea level, this is the highest point of the main Swiss railway network.
Breakthrough or break through may refer to:
Teredo navalis, the naval shipworm, is a species of saltwater clam, a marine bivalve mollusc in the family Teredinidae, the shipworms. This species is the type species of the genus Teredo. Like other species in this family, this bivalve is called a shipworm, because it resembles a worm in general appearance, while at the anterior end it has a small shell with two valves which is adept at boring through wood.
The Kander is a river in Switzerland. It is 44 kilometres (27 mi) long and has a watershed of 1,126 square kilometres (435 sq mi). Originally a tributary of the Aare, with a confluence downstream of the city of Thun, since 1714 it flows into Lake Thun upstream of the city.
The Lötschberg is an Alpine mountain massif and usually associated with a major, historically important transit axis of the Alps in Switzerland with, at its core, the Lötschen Pass. The mountain pass, which culminates at nearly 2,700 metres above sea level, are part of the eastern Bernese Alps, whose main crest straddles the border between the cantons of Berne and Valais. The valleys concerned by the Lötschberg are those of the Kander in the Berner Oberland, with Kandersteg at the head of it, and a secluded side-valley of the Upper Valais, the Lötschental, with Ferden at the valley's entrance and at the bottom of the pass.
The Lötschberg line is a railway in Switzerland, connecting Spiez in the canton of Bern with Brig in the canton of Valais. It crosses the Bernese Alps, from the Bernese Oberland to Upper Valais, through the Lötschberg Tunnel in the middle of the line. Together with the Simplon Tunnel south of Brig, it constitutes one of the major railways through the Alps and an important north-south axis in Europe. The Lötschberg axis is backed by the lower and longer Lötschberg Base Tunnel, part of the New Railway Links through the Alps project.
Heroes Tunnel is a 1,200-foot-long (370 m), twin-tube tunnel carrying Route 15 through West Rock Ridge in New Haven, Connecticut, opened in 1949. It was said to be the only vehicular tunnel "to pass beneath a land feature" in New England, but the statement is not accurate, as there are other vehicular tunnels in New England.
Visp railway station is a junction station at Visp, in the canton of Valais, Switzerland. It has a modern station building completed in 2007, and is served by two standard gauge lines and a metre gauge line.
The Greenwood Tunnel is a historic railroad tunnel constructed in 1853 by Claudius Crozet during the construction of the Blue Ridge Railroad. The tunnel was the easternmost tunnel in a series of four tunnels used to cross the Blue Ridge Mountains of Virginia. Located near Greenwood in Albemarle County, Virginia, the tunnel was used by the Chesapeake and Ohio Railway (C&O) until its abandonment in 1944. The tunnel still exists, though sealed, next to the old C&O line, now owned by CSX Transportation and leased to the Buckingham Branch Railroad, which runs through a cut bypassing the old tunnel.
The Brookville Tunnel was a historic railroad tunnel engineered by Claudius Crozet during the construction of the Blue Ridge Railroad in the 1850s. The tunnel was part of a series of four tunnels used to cross the Blue Ridge Mountains of Virginia for the Virginia Central Railroad of the United States. The Brookville Tunnel was the second tunnel used to cross the mountains from the east, and was located approximately 1.5 miles (2.4 km) west of the village of Greenwood, Virginia.
The Simplon Railway is a line that links Lausanne in Switzerland and Domodossola in Italy, via Brig. The 20 km (12 mi)-long Simplon Tunnel is a major part of it. The line between Lausanne and Vallorbe is sometimes considered to form part of the line, making it 233 km (145 mi) long.
