Railroads, Truss Bridges and the Rise of the Civil Engineer
The huge growth of the railroads during the nineteenth century was the direct result of herculean efforts on the part of civil engineers. Likewise, the development of the civil engineering...

Philadelphia-three ages of a city
On these pages are the profiles of the City of Brotherly Love in three eras. First come the founding years, and the story of why, though only half as old as Boston and New York, by 1750...

Stress Cycles for Fatigue Design of Railroad Bridges
Fatigue design criteria for railroad bridges are evaluated in the light of the latest research concerning fatigue. Railroad bridge loadings and stress histories of the primary and the...

State-of-the-Art of Ballastless Track at-Grade
Ballastless track support structures are regarded as possible solutions to the problems of track maintenance and the research and development of these structures is reviewed. The new types...

The Resurgence of Light Rail Transit
With the development of a new Standard Light Rail Vehicle there has been an increased interest in light rail systems for community mass transit. Light Rail Transit systems can be tailored...

Contribution to Selection of Railroad Ballast
Laboratory classification of 10 railroad ballasts used in a CNR field test is given. The 10 ballasts are rated for their field performance from the CNR test report. Each ballast is rated...

Effect of Foundation Stiffness on Track Buckling
The present paper deals with the effect of releasing the constraining assumption of using an infinitely rigid foundation in the analysis of vertical buckling of a railroad track due to...

Desperate Need to Slash Construction Cost of New Subways
Subways and subway stations cost far too much to build in the U.S. Whereas Londoners recently built 3-1/2 miles of subways and subway stations for only $18,000,000, the Washington Metro...

Rating and Reliability of Railway Bridges

Practical Applications of the Mini Computer to Structure in Railway Maintenance Programs

American Wooden Bridges
Wooden bridges are inimitably American. Their practicality, individuality, and ruggedness are traditional characteristics associated with our country. This publication catalogues some...

American Railroad Bridges

Vibration Measurements of Steel Transit Structures
Vibrations induced into rail rapid transit structures may be radiated from the structure as airborne noise that disturbs the rider and the wayside community, or as ground-borne vibrations...

Fifty-Year History of Movable Bridge Construction - Part I
Part I of this three-paper series reviews the history of movable bridges and follows the development of the construction of this type of structure during the past half century. In recent...

Ventilated Approach Regions for Railway Tunnels
A possible method of reducing the magnitudes of the pressure transients generated when railway trains enter tunnels at high speeds is described. Some such method will be required in the...

The Forgotten Engineer: John Stevens and the Panama Canal
John Frank Stevens was appointed by President Theodore Roosevelt in 1903 to take over the flagging Panama Canal project when John Wallace quit. Stevens had been an outstanding railroad...

Washington Metro Access Facilities
The 98 mi (158 km) Metro system will have 82 stations. There will be an off-street bus terminal at 54 of the stations with an average of six modified saw-tooth off-street bus bays at each...

Paratransit: How You May Get Around if the Energy Shortage Takes You Out of Your Car
Conventional rail and bus transit play important roles. Para-transit may eventually carry more people. Among the possibilities: priority access to freeways for multi-passenger vehicles;...
