Urban Gravity - Vacuum Transit System
Gravity-Vacuum Transit (GVT), a passenger transportation system which employs gravity and vacuum for propulsion, is described for urban applications. The physical principles are presented...

Load Distribution in Steel Railway Bridges
The study was undertaken to develop better design specifications for the distribution of live load in the floor systems of steel railway bridges. The paper briefly summarizes two methods...

Transporting Equipment for Grand Coulee Third Plant
Unusual problems encountered and solutions considered for transporting extremely heavy equipment for the Grand Coulee Third Power Plant are described. The power plant, ultimately to be...

Recorded Stress Histories in Railroad Bridges
Repeated application of stress resulting from locomotives and cars crossing a bridge may cause certain members of the bridge to become a fatigue subject. However, recorded stresses in...

Prestessed Precast Concrete Railroad Bridges
Prestressed, precast hollow concrete box girder units are now being used extensively for underpasses, trestle renewal and stream bridges by major Western U.S. railroads. Historical development...

Uncased Pipeline Crossings of Railroads and Highways

Modes of Transportation
Sources of Information on Urban Transportation
This book offers an inventory of modes of urban transportation classified by vehicle types, with subclasses by guideway where applicable. Over 100 vehicles systems which have been demonstrated....

Guard Rail And Safe Operation Of Highways
The use of guard rail on modern highways is presented. The development of the rail from the manner in which it was used as recently as 1960 to the present practice on Texas highways is...

High-Speed Trains for Washington - New York Service
Railroad cars capable of 160 mph speed are under construction at The Budd Company for use in the Department of Commerce High Speed Ground Transportation Demonstration Project. These cars...

Mass Transportation for the 1967 World Exhibition
An automated, 3-1/4-mile, steel wheel on steel rail rapid transit system, designed and built to serve visitors to the 1967 World Exhibition in Montreal, is described. Each of the eight...

Innovation in Mass Transit
After construction of rapid transit systems in several major American cities around the turn of the century, little was done to improve or develop new rolling stock until the 1950's....

Performance of Casting Pipes Under Railroads and Highways: Report of Research Council on Pipeline Crossings of Railroads & Highways
This report presents measurements and observations made of the performance of pipeline casings under railroads in several locations of the United States. Research was conducted to obtain...

Latest Development in Transporting Coal by Rail
Improved handling of coal trains to eliminate delays enroute have been effected by the use of unit trains. Coal transportation costs in some cases have been reduced from $3.07 per ton...

Functional Planning Bulk Material Ports
New concepts in material handling methods and equipment make it essential for the terminal planner to consider operational procedures to avoid premature obsolescence of port facilities....

Bolted Bridge Behavior During Erection and Service
Measurements were made of the movements at connections of a 310-ft railway bridge over a period of 3-1/2 yr. The study was initiated during shop-assembly of a truss and was ended after...

Unit Trains and Their Impact on Fuel Costs

Technological Aspects Of Urban Transportation
Automotive transportations systems appear to be best suited for most urban passenger trips because of the inherent flexibility of the private automobile in serving the expanding land uses...

Strain-Gage Analysis For Uncased Pipeline Crossing: Report of the Research Council on Pipeline Crossing of Railroads and Highway of Pipeline Division
From an analysis of strain gage data obtained by the Association of American Railway Laboratories for simulated highway and railroad crossings by uncased 8 in. and 12 in. pipelines, it...

Development and Use of the Modpares Device: Report of the Research Council on Pipeline Crossing of Railroad & Highways, Pipeline Division
This report develops the modpares device for measuring the modulus of passive resistance of soil. In an attempt to determine the moduli of passive resistance of a wide range of types of...

St. Anthony Falls Navigation Project
St. Peter sandstone is a soft loosely bonded rock that disintegrates readily when subjected to flowing water. This type of foundation, encountered in the St. Anthony Falls project, called...
