Commuter railroad systems in the US employ three combinations of station platforms and car entranceways. These are high-level platforms with remotely controlled doors and level entranceway (HL-RC), low-level platforms (just above the rail) with steps and remotely controlled doors (LL-RC), and a mixture of the two platform types with a correspondingly more complex, partly manual, door and entran...

The object of this study is the processes related to emergence, perception, and redistribution loads in improved structure a passenger car frame. scientific applied task tackled paper ensure strength supporting under operating loads. In regard, it proposed improve frame by constructing girder beam from two rectangular pipes filled with material energy-absorbing properties. regularities load hav...

This paper examines the historical impact of railroads on the American economy. Expansion of the railroad network and decreased trade costs may affect all counties directly or indirectly, an econometric challenge in many empirical settings. However, the total impact on each county can be summarized by changes in that county’s “market access,” a reduced-form expression derived from general equil...

Indian Rail transport is one of the major mode of transportation, so it must offer high comfort level for the passengers and the staff. However, the comfort that passengers experience is a highly complex and individual phenomenon. The improvement of passenger comfort while travelling has been the subject of intense interest for many train manufacturers, researchers and companies around the worl...

Semantic query optimization can dramatically speed up database query answering by knowledge intensive reformulation. But the problem of how to learn the required semantic rules has not been previously solved. This chapter presents a learning approach to solving this problem. In our approach, the learning is triggered by user queries. Then the system uses an inductive learning algorithm to gener...

As World population is exponentially increasing big cities face traffic and safety challenges related to railroad and rapid ground transportation projects. For this reason, to avoid collisions and allow a better communication between train, central control headquarters, and passengers new technologies are being developed by means of very sophisticated technologies. This project, being focused i...
