The Arras sector of the Western Front in World War I (WW1) was held partly by the British and Dominions 1st Army from September 1915, and almost wholly by the 1st and 3rd Armies from March 1916. No less than in the Ypres sector to the north and the Somme sector to the south, the struggles of the French and then British troops in this sector were pivotal to the outcome of the War. The sector included countryside in the south, but in the north a major part of the industrial and coal-mining area of northern France, around Lens and Bthune. In this book the contribution of metre and 60 cm gauge railways to the Allied war effort in this sector is examined in the context of the history of the metre gauge lines already established. The build up of light (60 cm gauge) lines from 1916 is examined in detail area by area, and the contribution of the related metre gauge lines is reassessed, from British and French sources. After the War the role of these railways in the reconstruction and recovery of this devastated region of France is described. Later the surviving part of the 60 cm gauge network served the sugar beet industry east of Arras. The history is followed through another World War to the closure of the last of these railways in 1957.The book refers to previous works on British War Department light railways in WW1, but contains sufficient general information for readers new to the subject. It also describes how to find key locations now, and how and where rolling stock can be seen. Six walks and an urban tour are included for those who wish to explore the territory in greater depth.

Includes 2 charts, 7 maps, 7 figures and 5 Illustrations. Renowned Military Historian Dr Christopher Gabel charts the decline of the Confederate Railways system that was to spell ultimate doom to the outnumbered soldiers of the Southern states. Military professionals need always to recognize the centrality of logistics to military operations. In this booklet, Dr. Christopher R. Gabel provides a companion piece to his “Railroad Generalship” which explores the same issues from the other side of the tracks, so to speak. “Rails to Oblivion” shows that neither brilliant generals nor valiant soldiers can, in the long run, overcome the effects of a neglected and deteriorating logistics system. Moreover, the cumulative effect of mundane factors such as metal fatigue, mechanical friction, and accidents in the civilian workplace can contribute significantly to the outcome of a war. And no matter how good some thing or idea may look on paper, or how we delude ourselves, we and our soldiers must live with, and die in, reality. War is a complex business. This booklet explores some of the facets of war that often escape the notice of military officers, and as COL Jerry Morelock intimated in his foreword to “Railroad Generalship,” these facets decide who wins and who loses.

US Navy rail operations on Oahu began in 1908 with construction railroads used to help build the shipyard. Expansion of Pearl Harbor to include the submarine base and the naval magazine on Kuahua Island required a permanent railroad, which was begun in 1911. This construction provided industrial employment to hundreds of local men in the existing agricultural economy, and the influx of additional manpower from the mainland contributed to an increasingly skilled and diverse population. World War II brought about a dramatic increase in Navy railroad operations in support of the war effort. Success in the Pacific theater of operations depended on the Navy's railroads, equipment, and the Oahu Railway & Land Company (OR&L), which connected all the bases. The OR&L abandoned its main line in December 1947. By the mid-1950s, railroad operations at Pearl Harbor also ceased. Rail operations continued at and between Naval Magazine Lualualei and Ammunition Depot West Loch through the Korean Conflict and Vietnam era, ending in 1972.

During the course of this century, gauge invariance has slowly emerged from being an incidental symmetry of electromagnetism to being a fundamental geometrical principle underlying the four known fundamental physical interactions. The development has been in two stages. In the first stage (1916-1956) the geometrical significance of gauge-invariance gradually came to be appreciated and the original abelian gauge-invariance of electromagnetism was generalized to non-abelian gauge invariance. In the second stage (1960-1975) it was found that, contrary to first appearances, the non-abelian gauge-theories provided exactly the framework that was needed to describe the nuclear interactions (both weak and strong) and thus provided a universal framework for describing all known fundamental interactions. In this work, Lochlainn O'Raifeartaigh describes the former phase. O'Raifeartaigh first illustrates how gravitational theory and quantum mechanics played crucial roles in the reassessment of gauge theory as a geometric principle and as a framework for describing both electromagnetism and gravitation. He then describes how the abelian electromagnetic gauge-theory was generalized to its present non-abelian form. The development is illustrated by including a selection of relevant articles, many of them appearing here for the first time in English, notably by Weyl, Schrodinger, Klein, and London in the pre-war years, and by Pauli, Shaw, Yang-Mills, and Utiyama after the war. The articles illustrate that the reassessment of gauge-theory, due in a large measure to Weyl, constituted a major philosophical as well as technical advance.
