Exploration of Ground Penetrating Radar for Railroad Tie Maintenance Scheduling
Assessment of railroad ties for replacement is currently performed by visual inspection. This paper describes a method of automated tie assessment using ground penetrating radar (GPR)...
Using Condition Indexes to Evaluate Local Railroad Track Networks
The U.S. Army Construction Engineering Laboratories (USACERL) have developed condition indexes for assessing track condition that apply to local railroads. Indexes were developed for the...
TRACK(1.0): A Railroad Track Design and Evaluation Computer Program for Work Planning and Budgeting
This paper describes TRACK, a track structural analysis method and computer program developed by the U.S. Army Construction Engineering Research Laboratories. TRACK is a program for evaluating...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
Planning Maintenance and Rehabilitation Activities for Local Railroads
This paper presents a structured approach for planning annual and long range (multi-layer) maintenance and rehabilitation (M&R) activities for local railroads. A method is presented...

High Speed Transportation for the 21st Century: Florida's High Speed Rail and Maglev Projects
This paper presents a brief status report on the State of Florida high speed ground transportation efforts. It includes a description of the amended high speed transportation act in Florida...
High Speed Ground Transportation: Some Historical Perspectives
The definition of `high speed' ground transportation is relative to the transportation technology of a period. Thus it might be argued that high speed ground transportation began early...
Evaluation of HSGT Systems Under Uncertainty
The basic themes of this paper are two-fold. First we investigate what planning style is likely to be most suited for planning an HSGT system, dependent on three interdependent key variables:...
Carrying Freight on High Speed Rail Lines
Some basic technical aspects of carrying freight on high speed rail lines are presented. To illustrate certain requirements and considerations, performance comparisons are made using three...
Experience in the Planning of High Speed Rail Lines: From Feasibility Studies to the Construction Project
For the construction of a new line for high speed traffic, a series of technical, commercial and economic studies must be carried out for each of the parts of the planning stage: the feasibility...
High Speed Rail: An Alternative Route to Preserve Quality of Life in the Northwest
