Cost-Effectiveness Review of Railroad Electrification

A comparison was made between the costs of electric and diesel-electric motive power to haul traffic projected for the 1975-2005 time period over a hypothetical network of high density mainline routes carrying about 50 percent of the 1975 traffic. The routes were selected from the Federal...

The Kansas Test Track: Non-Conventional Track Structures Design Report

This report discusses the design of three non-conventional Railroad track support structures. These non-conventional structures, which include a continuously reinforced concrete slab, twin cast-in-place concrete beams, and twin precast concrete beams, are part of a research program to develop...

The Feasibility of Magnetically Levitating High Speed Ground Vehicles

To determine technical feasibility of magnetically levitated and guided high-speed ground transportation vehicles theoretical analyses of four suspension systems were conducted: (1) permanent magnet, (2) electromagnet-ferromagnetic guideway, (3) superconducting magnet, conducting coil guideway...

Light Rail Transit Systems: a Definition and Evalution

Rail transit represents a family of modes ranging from light rail to regional rapid transit systems, and it can be utilized in a number of different cities and types of applications. Many European cities of medium size employ very successfully light rail mode for gradual upgrading of transit...

Embankment Support for a Railroad Track: Construction Report

This report discusses the construction of three non-conventional railroad track support structures. These non-conventional structures, which include a continuously reinforced concrete slab, twin cast-in-place concrete beams, and twin precast concrete beams, are part of a program to develop...

Tunneling Cost Analysis

This report provides the Office of High Speed Ground Transportation with a review and analysis of tunnel construction costs. The data for all cost analyses in the report were obtained from historical records of tunnel owners, contractors, and equipment and material manufacturers throughout the...

Preliminary Vibration Measurement on Mark I Vehicle

Preliminary measurements have been made on the acceleration and vibration environment of the Mark I vehicle while operating on the New York City Transit System. Measurements at the journal box indicated short period high acceleration pulses as large as 120g with durations of about one milli-...

Embankment Support for a Railroad Test Track: Design Studies

The events and considerations leading up to the production of an embankment design for the support of the Kansas test track are described. Included are discussion of: site description, field investigations, laboratory investigations, sub-surface conditions, embankment design, and instrumentation...

Tracked Air Cushion Vehicle Systems

The tracked air cushion vehicle is one of several advanced ground transportation systems being studied by TRW Systems Group for the Department of Transportation as a possible means of providing safe, high-speed, high-capacity transportation along densely populated areas such as the Northeast...
