INTRODUCTION The purpose of contract DOT/TSC-913 is to develop a locomotive cab design based on the operator's functional requirements in train operation. The design is predicated on human engineering and other engineering disciplines leading to specifications which are suitable for the design, development, test and evaluation of a cab that is in concert with all operational and safety conditions. The locomotive cab design is based on the most complex set of functional requirements, which are, as anticipated, based on line- haul operational needs. This report presents an analysis of the line-haul freight engineer's working and living environment and the resultant locomotive cab design and design alternatives. The analysis is based on a delineation of functional requirements inherent in contemporary line-haul operations together with those additional situations which might conceivably arise during the next 10-15 years. The recommended design is the result of a detailed human factors engineering analysis of these requirements in accordance with state-of-the-art criteria in railroad operations and system design practices. The technical content is presented in the following sections and a summary is presented below. First, however, it is appropriate to offer a brief description of the freight engineer's working environment to place the analysis in perspective. Today's locomotive engineers are, and will, at least in the foreseeable future, continue to be exposed to a wide variety of assignments. Each task has its own peculiar set of train handling requirements. The economics of train makeup and manpower utilization may dictate, on the one hand, the employment of longer and heavier trains traveling at slower speeds, while on the other hand, short, fast trains which run at frequent intervals ap pear to hold some promise for the economical movement of produce and merchandise. Locomotive consists are getting longer because trains are heavier and need more tractive effort. Locomotives may be inserted in the train at critical points as helper units, operating either remotely from the front of the train or manned. The trains themselves are usually made up of a mix of loads and mass diatribution in combinations of old and new cars as the result of destination blocking.

Abstract:-Most of the accidents in four wheeled vehicles occurs due to failure of braking systems. Manual method of applying brakes as it leads to accidents the linkages of braking systems, road conditions, uncontrollable speed of the vehicle and manual operation of braking systems are the reason of accidents. It is necessary to control brakes automatically through electronics devices to reduce accident problems. In this research paper we design an effective methodology for automatic control of braking system to avoid accidents. We used Arduino, relays, IR transmitter, and IR receiver for the effective function of braking control system. This complete system can be fixed on the dashboard of a vehicle and effectively used for automatic control of braking system. Vehicle accidents are everywhere in recent years. This is because of increase in population of vehicles, due to its high demand. A system must be designed to reduce the accidents.. The technology of pneumatics plays a main role in the field of automation and modern machine shops.. IR sensor fixed on the front end of the vehicle detects the presence of the obstacle. The use of pneumatic system can be useful in automation due to its simplicity and ease of operation. The past experiment results show that the control method can be improve the braking performance of a vehicle. So, the objective is to develops a system based on automatic control of vehicle.

Each of the four 7ft 6in rods weighs around two hundredweight and after forging, extensive machining and heat treatment, the four cost around £22,000 to manufacture. These rods are vital components within the £150,000 valve gear and motion assemblies, which are now the focus of work on Tornado at the Trust’s Darlington Locomotive Works. The Trust has also started work on the fitting of the rest of the outside motion. The bushes for the connecting rods are currently being machined at Ian Howitt Ltd, Wakefield and one side of the locomotive has now been fitted with a mock-up of parts of its valve gear. This is to enable accurate measurements to be taken to set the length of the eccentric rod as the traditional method of heating the rod to stretch/shrink it used when the original Peppercorn A1s were built in 1948/9 is no longer recommended as it can affect the rod’s metallurgical properties.

A Railway Tridea F.H.Howard P Eng Richmond B C 1. RUBBER AND RAIL The ability of a locomotive to exert tractive effort or drawbar pull - the measure of what it could lift vertically, say over the edge of a cliff - and so, once the train's resistance has been determined, what tonnage of train it can start, is restricted by its wheen adhesion to the rails, normally about /14 of its weight. wheel slip control (replacing sanding) has now raised this to about 1/3. Too much power, and its wheels will slip. Starting a train is adhesion-limited; running it is horsepower-limited. When inverted, this fraction becomes "Factor of Adhesion" and refers to steel wheels gripping - or slipping - on steel rails. Some locomotives are ballasted to achieve adhesion, which affects braking too.. Heavier trailing tonnages can be moved if a much lower Factor of Adhesion can be developed. Such a low factor is indeed developed by rubber on paving. Assuming the road is dry and the tires sound, a rubber-tired highway tractor can lift half its own weight, with the corresponding capacity to pull a heavy trailing load, usually a semi-trailer, also on rubber tires. 1 Howard 419 A number of rail vehicles use a Hi-Rail device,. hydraulically-lowered sets of rail wheels, commonly attached to rubber-tired track inspection and maintenance equipment, especially automobiles, pickup trucks or vans; sometimes little cranes.

    Railway power supply system models for static calculations in a modular design implementation Usability illustrated by case-studies of northern Malmbanan RONNY SKOGBERG Master’s Degree Project Stockholm, Sweden 2013 XR-EE-ES 2013:006 Railway power supply system models for static calculations in a modular design implementation Usability illustrated by case-studies of northern Malmbanan RONNY SKOGBERG Master of Science Thesis Royal Institute of Technology School of Electrical Engineering Electric Power Systems Stockholm, Sweden, 2013 Supervisors: Lars Abrahamsson, KTH Mario Lagos, Transrail AB Examiner: Lennart Söder XR-EE-ES 2013:006 Abstract Several previous theses and reports have shown that voltage variations, and other types of supply changes, can influence the performance and movements of trains. As part of a modular software package for railway focused calculations, the need to take into account for the electrical behavior of the system was needed, to be used for both planning and operational uses. In this thesis, different static models are presented and used for train related power flow calculations. A previous model used for converter stations is also extended to handle different configurations of multiple converters. A special interest in the train type IORE, which is used for iron ore transports along Malmbanan, and the power systems influence to its performance, as available modules, for mechanical calculations, in the software uses the same train type. A part of this project was to examine changes in the power systems performance if the control of the train converters were changed, both during motoring and regenerative braking. A proposed node model, for the static parts of a railway power system, has been used to simplify the building of the power system model and implementation of the simulation environment.
