Train Is On Track

Train is speeding through the countryside when Dog sees a red signal. There's a fallen tree and the mail train is stuck! How can Train help to keep the mail moving? It's time to get busy with machines that race, vroom and zoom! This vibrant series is designed to excite playful pre-schoolers. Each story features a popular vehicle as the central character, and involves a group of animal characters in a supporting role. A detailed spread on different parts of the vehicle will help children tom understand what makes up the machines and help familiarise them with vehicle vocabulary and noises.

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.

All aboard for a train ride brimming with 101 fun-filled flaps to lift and clever rhyming text to read from left to right or top to bottom!

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.

All aboard the farm train! Complete with tractor wheels, a happy farmer, and the loudest passengers you've ever heard, Farm Train is an adorable two-in-one board book that features brightly illustrated farm animals in every train car. The cow says moo moo, the sheep says baa baa, and the goose says honk honk from the moment the train leaves the station. Farm Train can be read page-by-page as a lap book or be unfolded into a 42" train! (Perfect for play time or room decor!) A handy velcro clasp keeps everything snugly shut when reading time is over.

Trixie and Tracky are disappointed when the wooden train set they join is full of bossy trains and snoring train tracks.

A ticket on the Magic Train takes the reader from outer space to underwater to a land of cakes.

TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.

Easy-to-read, rhyming text describes the sounds of, and uses for, different kinds of trains.

A toy and a book in one, this large, chunky board book comes with a wind-up toy steam train. Wind the train up and set in on the embedded track in each page to see it chugging along through the countryside. Each of the four tracks is removable, and together they combine to make one giant train track.
