This challenging visual puzzle will appeal to lovers of logic and deduction brain teasers. How To Play: A map grid shows two towns, typically A and B. The objective of the puzzle is to lay down tracks to connect the two towns. Numbers around the outside of the grid tell you how many pieces of track are to be placed in each row and column. You can only use straight (horizontal and vertical) and curved (right and left) rails and the track cannot cross over itself. There is something very satisfying in the laying down of tracks. The puzzles are arranged with varying levels of difficulty, where difficulty is largely dependent on the size of the map grid (from 6x6 to 10x10). Puzzles included cover three levels of difficulty: 70 Easy, 70 Moderate, and 60 Difficult.

In wide-ranging and provocative analyses of dozens of silent films - icons of film history like The General and The Great Train Robbery as well as many that are rarely discussed - Kirby examines how trains and rail travel embodied concepts of spectatorship and mobility grounded in imperialism and the social, sexual, and racial divisions of modern Western culture.

During the tumultuous year of 2008--when gas prices reached $4 a gallon, Amtrak set ridership records, and a commuter train collided with a freight train in California--journalist James McCommons spent a year on America's trains, talking to the people who ride and work the rails throughout much of the Amtrak system. Organized around these rail journeys, Waiting on a Train is equal parts travel narrative, personal memoir, and investigative journalism. Readers meet the historians, railroad executives, transportation officials, politicians, government regulators, railroad lobbyists, and passenger-rail advocates who are rallying around a simple question: Why has the greatest railroad nation in the world turned its back on the very form of transportation that made modern life and mobility possible? Distrust of railroads in the nineteenth century, overregulation in the twentieth, and heavy government subsidies for airports and roads have left the country with a skeletal intercity passenger-rail system. Amtrak has endured for decades, and yet failed to prosper owing to a lack of political and financial support and an uneasy relationship with the big, remaining railroads. While riding the rails, McCommons explores how the country may move passenger rail forward in America--and what role government should play in creating and funding mass-transportation systems. Against the backdrop of the nation's stimulus program, he explores what it will take to build high-speed trains and transportation networks, and when the promise of rail will be realized in America.

Empire’s Tracks boldly reframes the history of the transcontinental railroad from the perspectives of the Cheyenne, Lakota, and Pawnee Native American tribes, and the Chinese migrants who toiled on its path. In this meticulously researched book, Manu Karuka situates the railroad within the violent global histories of colonialism and capitalism. Through an examination of legislative, military, and business records, Karuka deftly explains the imperial foundations of U.S. political economy. Tracing the shared paths of Indigenous and Asian American histories, this multisited interdisciplinary study connects military occupation to exclusionary border policies, a linked chain spanning the heart of U.S. imperialism. This highly original and beautifully wrought book unveils how the transcontinental railroad laid the tracks of the U.S. Empire.

Measured geodesic laminations are a natural generalization of simple closed curves in surfaces, and they play a decisive role in various developments in two-and three-dimensional topology, geometry, and dynamical systems. This book presents a self-contained and comprehensive treatment of the rich combinatorial structure of the space of measured geodesic laminations in a fixed surface. Families of measured geodesic laminations are described by specifying a train track in the surface, and the space of measured geodesic laminations is analyzed by studying properties of train tracks in the surface. The material is developed from first principles, the techniques employed are essentially combinatorial, and only a minimal background is required on the part of the reader. Specifically, familiarity with elementary differential topology and hyperbolic geometry is assumed. The first chapter treats the basic theory of train tracks as discovered by W. P. Thurston, including recurrence, transverse recurrence, and the explicit construction of a measured geodesic lamination from a measured train track. The subsequent chapters develop certain material from R. C. Penner's thesis, including a natural equivalence relation on measured train tracks and standard models for the equivalence classes (which are used to analyze the topology and geometry of the space of measured geodesic laminations), a duality between transverse and tangential structures on a train track, and the explicit computation of the action of the mapping class group on the space of measured geodesic laminations in the surface.

Jack, a railroad switchman, frantically tries to save an ant who is heading east on a westbound track, straight into the path of an oncoming freight train.
