Lancaster County is a popular tourist destination, due mostly to the many plain sect residents, known as the Amish or Pennsylvania Dutch. The term 'Pennsylvania Dutch' comes from the earlier use of "Dutch" to apply to all immigrants from middle Europe. They are the descendants of Germans who immigrated in the 18th and 19th centuries for the freedom of religion offered by William Penn, and were attracted by the rich soil and mild climate of the area.
Lancastrians can easily spot a visitor to the area by how they pronounce the word Lancaster. Locals and people from nearby counties in Pennsylvania, Maryland, and Delaware pronounce Lancaster as LANK-ister. This is unusual as most Lancasters in the United States are pronounced as LAN-cast-er, though Lancashire, England, and Lancasters in Texas, Ohio, and South Carolina also use the LANK-ister pronunciation.
Lying on the natural route from Philadelphia to the western part of Pennsylvania, Lancaster County has given rise to many improvements in transportation, among them the Philadelphia and Lancaster Turnpike, later part of the Lincoln Highway, in 1794, a canal in 1820 and the Philadelphia and Columbia Railroad in 1834.
Highways Lancaster County's highways include the Pennsylvania Turnpike (or Interstate 76), U.S. Route 30 (or the Lincoln Highway), U.S. Route 222, and U.S. Route 322. Pennsylvania State Routes in the county include: 10, 23, 41, 72, 230, 241, 272, 283, 324, 340, 372, 441, 462, 472, 501, 625, 741, 743, 772, 896, 897, and 999.
Current railroads As of 2006, passenger service in Lancaster County is provided by Amtrak, whose Keystone Corridor passes through the county, with stops at Lancaster, Mount Joy and Elizabethtown. A station is planned at Paradise to provide connecting service with the Strasburg Railroad, which runs passenger excursions from nearby Leaman Place to Strasburg.
The principal freight operator in the county is Norfolk Southern Railway (NS). The NS main line follows the Susquehanna River (with trackage rights for Canadian Pacific Railway (CPR)), and leaves the county by crossing the river on Shocks Mills Bridge near Marietta. NS also has trackage rights over the Keystone Corridor, to which it is connected by the Royalton Branch, which runs north along the river from the main line at Marietta, and the Columbia Branch, which runs from the Corridor at Dillerville to the main line at Columbia. Two other NS branches originate on the Corridor: the Lititz Secondary, which runs from Dillerville to Manheim and ends at Lititz, and the New Holland Industrial, which leaves the Corridor around the east end of Lancaster to run east to New Holland and ends at East Earl.
Several shortlines also operate in the county. With the exception of the Strasburg Railroad, all are freight railroads. Penn Eastern Rail Lines (PRL) operates on a spur off the NS branch to Manheim, and on a longer line in the northeast corner of Lancaster County into Berks County. Landisville Terminal and Transfer Company (LNTV) operates on a spur off the Amtrak line at Landisville. The Tyburn Railroad operates some trackage around Dillerville. Frank Sahd Salvage, Inc., of Columbia, has received state funds to repair 2.5 miles (4.0 km) of track there for operation, probably by the Penn Eastern, but this has not yet been returned to service.
Lancaster Airport is the only airport in the county with scheduled service, though Smoketown Airport also serves general aviation.
