Abstract:

The movement of freight on railroads, like most transportation services, is subject to a number of restrictions that make costing of specific traffic a complex process. Among these restrictions are conditions of joint production; economies of scale, scope, and density; and a lack of data on specific expenditures as related to individual freight movements. Yet costing of specific movements is a desirable activity for shippers, railroads, and regulatory bodies. Traditionally, movement costing has involved the use of accounting-based allocative costing models such as the Uniform Rail Costing Syst

Abstract:

One way to keep the train service flow runs safely, maintenance of railroad geometry is required. Maintenance of railroad tracks uses the Track Quality Index assessment to determine which railroad compartments or corridors are prioritized for repair. The research method used is a quantitative research method. The calculation of the TQI of railroad tracks includes force, height, spoor width and lining. The results of the calculation of the TQI value (manual) give the cumulative total number of standard deviation index is 21.6. While the TQI calculation (mechanical) total cumulative number index

Abstract:

As railroad infrastructure becomes older and older and rail transportation is developing towards higher speed and heavier axle, the risk to safe rail transport and the expenses for railroad maintenance are increasing. The railroad infrastructure deterioration (prediction) model is vital to reducing the risk and the expenses. A short-range track condition prediction method was developed in our previous research on railroad track deterioration analysis. It is intended to provide track maintenance managers with two or three months of track condition in advance to schedule track maintenance activi

Abstract:

A gigantic evolution has been brought about in the railway transportation by the emergence of the expressways as the most efficient method of carrying passengers within short and medium interurban distances. Various types of expressway pavements have been offered during the recent years.

Abstract:

Adequate lateral resistance is required to provide the stable track structure necessary for safe rail operations on passenger and freight railroad track. Insufficient lateral resistance, coupled with a large thermal compression force in the rail from high rail temperature, can buckle the track structure. Railroads typically use mechanical stabilization, slow orders, or both, following maintenance operations that disturb the ballast section, such as track surfacing and alignment. Tests were conducted to improve the understanding of lateral resistance variations on concretetie track caused by su

Soil pollution around railroad sites is mainly caused by heavy oils such as diesel and lubricants. In particular, the majority of contamination in soil around railroad turnouts is caused by oil that drips off of railcars and lubricants that leak during vehicle maintenance. Generally, removing lubricants from contaminated soil is more difficult than removing diesel, due to the properties of the respective oils. This study aims to investigate alternative remediation method of lubricant-contaminated soils around railroad turnouts. The EK-Fenton process was used to clean up the lubricant-contamina

Abstract:

The methods that are widely used today to determine the required locomotive fleet, the Corresponding maintenance and repair system consider the locomotive as a whole, without taking into account the technical condition of its individual units, which have a limited life cycle. Furthermore, the methods used today do not take into account the time spent on relocation from an operational locomotive depot to a service depot and back. The purpose of this study is to develop the methods for determining the number of locomotives based on the anticipated workloads for specific operational sections, the

Abstract:

Accurate information on future railroad track condition is essential to optimally schedule track Maintenance & Renewal activities in order to minimize influences of the activities on rail traffic under constraints of limited budgets and maintaining allowable condition tracks. In this paper, a track measurement data mining method is presented to this aim. It is developed on the basis of track deterioration characteristics. Actual track measurement data is used to analyze errors in track condition predictions by the method. The analysis results show that the proposed method can mine accurate

Abstract:

ABSTRACT In July 1978, several homes near the Burlington Northern Railroad yards in North La Crosse reported fuel oil in their basements. High water tables and flooding along the La Crosse River caused seepage into the basements. The nearby railroad refueling depot was the only likely source of the product. A review of railroad activities indicated several likely sources for fuel oil leakage into the soil. A contractor was hired and a recovery system was installed. The recovery system removed about 300 gallons of fuel oil per day. Because of several operational problems, this recovery system w

Abstract:

In the Eurasian railway network, a different gauge length is used across several countries. A railroad variable gauge allows railway vehicles in rail transport to travel across a gauge break caused by two railway networks with differing track gauges. The variable gauge railway consists of the bogie system to change the length of the wheel shaft and the gauge changing railroad track. Thus, it is important to assess the structural performance of the variable gauge system. In this study, as a performance improvement subject of the variable gauge bogie and railroad, a structural analysis using dyn
