The participants in the grain logistics system need forecasts of railroad grain carloads. Although forecasting studies have been conducted for virtually every mode, no forecasting studies of quarterly railroad grain transportation have been published. The objectives of the paper are (1) specify a US quarterly railroad grain transportation forecasting model, and (2) empirically estimate the mode...

Indian railway is one of the largest networks in country. Its motto “the life line country”, and main transport completed by railways Railroad cheapest safest means transport, but there are also certain accidents on railroad. 60% caused road failures or formation cracks road. Today’s rail systems involve manual track inspection, which cumbersome not entirely effective. However, detection correc...

Communication protocols issues are one of the effective factors in communicated networks performance. One of challenging problem in CMT-SCTP which sends data by multipath concurrently is Receive Buffer Blocking. This problem has important role in data transmission speed in computer networks. In this paper, we propose a control method based on fuzzy logic so that can solve Receive Buffer Blockin...

The new Qinghai-Tibet railroad will run across the world’s highest permafrost region for 632 km, of which about half is high-temperature and ice-rich permafrost. Therefore, an important and challenging engineering problem is the possible instability and sensitivity of permafrost. Chinese permafrost scientists are now making efforts to solve the problem by carrying out numerous field and laborat...

The number of railroad events reported to the Agency for Toxic Substances and Disease Registry's Hazardous Substances Emergency Events Surveillance system increased from 84 in 1993 to 177 in 1998. Comparisons of data on railroad and non-railroad events were made. The results overall indicated a greater potential impact of railroad events on public health. A median number of 2039 persons were li...

In-plant railroad engine scheduling involves routing and scheduling decisions for a heterogeneous fleet of switching engines to serve a set of time-windowand capacity-constrained transportation requests. Despite an ever-increasing competition, the current planning is purely by pencil and paper. Our paper describes the mathematical and algorithmic developments for addressing in-plant railroad de...

Railroad trespassers are persons on railroad property whose presence is prohibited or unlawful. Most trespassers are walking along or across railroad tracks. In 1997, fatalities to railroad trespassers became the leading cause of railroad-related deaths in the United States. In 1998, 513 persons were injured and 536 persons were killed while trespassing (Federal Railroad Administration, unpubli...
