Opened in 1957, Tweetsie Railroad began as an excursion train ride pulled by steam locomotive #12, the only surviving narrow gauge engine of the East Tennessee and Western North Carolina Railroad (ET&WNC).
 Built in 1917 by the Baldwin Locomotive Works, #12 is a narrow gauge 4-6-0 coal-fired locomotive that was used from 1918 to 1940 to haul passengers and freight over the ET&WNC's 66 mi line running through the Appalachian Mountains from Johnson City to Boone, North Carolina.
 The name "Tweetsie" was given to the original East Tennessee and Western North Carolina Railroad by area residents who became accustomed to the shrill "tweet, tweet" of the train whistles that echoed through the mountains.
 The nickname stuck with the railroad and its trains, and became more identifiable than the railroad's original name.

Maryland Route 272 (MD 272) is a state highway in the U.S. state of Maryland.
 The state highway runs 20.67 mi from Turkey Point within Elk Neck State Park north through North East to the Pennsylvania state line near Calvert, where the highway continues as Pennsylvania Route 272 (PA 272).
 MD 272 is the main north–south highway of central Cecil County, connecting the Elk Neck between the North East River and Elk River with U.S. Route 40 (US 40) and Interstate 95 (I-95) in North East, MD 273 in Calvert, and Rising Sun via MD 274.
 The section of MD 272 between North East and Bay View was paved by 1910.
 The remainder of the state highway north to Calvert and south to Elk Neck was completed in several sections in the 1930s.
 The first relocations of MD 272 occurred when both railroads near North East were bridged in the early 1940s and mid-1950s.
 Multiple relocations occurred in the late 1950s and early 1960s along the whole length of the highway to eliminate curves and tie the state highway into I-95.
 MD 272 reached its current extent when it was extended south into Elk Neck State Park in 1979.
