Excerpt from Cross Tie Forms and Rail Fastenings With Special Reference to Treated Timbers In a circular issued at that time. The Commissioner said. Millions of feet of tanbark or chestnut oak are rotting in the forest after being stripped of their bark. Because their value for cross-ties is not known or is underestimated in many regions. He appealed to the railroad companies to use this wood so far as possible for ties, in order not onlv to avoid this waste but also to preserve the supply of white oak. His appeal resulted in a brief effort on the part' of some companies, but this lasted only a short time. The planting of trees has from time to time engaged the attention of farsighted men. A notable example is a grove of catalpa trees planted at Farlington. Kain in 1880. By Major Hunnewell. Then connected with the Kansas City. Fort Scott and Memphis Railroad. It certainly is important for every large user of timber to encourage the replanting of denuded areas with such species of trees as will be most useful in the particular region. The question of future supply, however. Is not within the province of the present bulletin. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
