This research paper is an initiative to provide insight associated with physiological health of employees’ by examining the interventions of yogic exercise on physiological health. The investigation was done to study the impact of Yoga and Pranayama on functioning of Lungs (vital capacity) and functioning of heart (resting heart rate) as an ancient therapy. The purpose of the study was found out the effect of aerobic exercise and yogic practices on resting pulse rate and vital capacity among employees of a private organization engaged in production of technical equipment’s for Indian Railway & Metro Trains & other such related industries. After taking due consent from the promoter and founder of PPS International, researcher randomly selected 120 subjects all males of age group 25-35years. Yoga helps to improve the lives of all age group irrespective of gender. It can be adopted from any stage of life or started at any age; yoga has shown excellent results on physiological health related variable of stressed working professionals.

Parametric Analysis of the Ride Comfort of Indian Railway Vehicle

This paper focuses to the parametric analysis of Indian Railway Rajdhani (LHB) coach. A suitable mathematical model of 40 degrees of freedom (DOF) is formulated by Lagrangian method. The mathematical model of rail-vehicle is modelled by considering eleven mass system containing of backseat support (without cushion), a seat, a car body, two (front and Rear) bolsters, two (front and Rear) bogie frame and four wheelaxles (front bogie front and rear wheel axles and rear bogie front and rear wheel axles. The vehicle is simulated to travel at speed of 100 km/hr on a tangent track. The results from the simulation are validated by comparing the same with the results from experimental data which is acquired from research designs and standards organization (RDSO), Lucknow (India). The parametric analysis is performed to estimate the effect of different parameters of rail-vehicle on the ride behaviour.

Static response of curved steel thin-walled box-girder bridge subjected to Indian railway loading

Purpose: The primary objective of the current study is to numerically model the steel thin-walled curved box-girder bridge and to examine its various response parameters subjected to Indian Railway loading. Design/methodology/approach: The analysis is conducted by adopting a one dimensional curved thin-walled box-beam finite beam element based on finite element methodology. The scope of the work includes a computationally efficient, three-noded, one-dimensional representation of a thin-walled box-girder bridge, which is especially desirable for its preliminary analysis and design phase, as well as a study of the static characteristics of a steel curved bridge, which is critical for interpreting its dynamic response. Findings: The analytical results computed using finite element based MATLAB coding are presented in the form of various stress resultants under the effect of various combinations of Indian Railway loads. Additionally, the variation in different response parameters due to changes in radius and span length has also been investigated. Research limitations/implications: The research is restricted to the initial design and analysis phase of box-girder bridge, where the wall thickness is small as compared to the cross-section dimensions. The current approach can be extended to future research using a different method, such as Extended finite element technique on curved bridges by varying boundary conditions and number of elements. Originality/value: The validation of the adopted finite element approach is done by solving a numerical problem, which is in excellent agreement with the previous research findings. Also, previous studies had aimed at thin-walled box girders that had been exposed to point loading, uniformly distributed loading, or highway truck loading, but no research had been done on railway loading. Moreover, no previous research had performed the static analysis on thin-walled box-girders with six different response parameters, as the current study has. Engineers will benefit greatly from the research as it will help them predict the static behaviour of the curved thin-walled girder bridge, as well as assess their free vibration and dynamic response analysis.

Railway Track Failure Detection System

Indian railway is one of the largest networks in the country. Its motto is “the life line of the country”, and the main transport is completed by the railways of the country. Railroad is one of the cheapest and safest means of transport, but there are also certain accidents on the railroad. 60% of accidents are caused by road failures or the formation of cracks in the road. Today’s rail systems involve manual track inspection, which is cumbersome and not entirely effective. However, the detection and correction of track defects is a problem for all railway companies in the world. The objective of this research work is to detect railroad track failures with the help of ultrasonic sensor and show the exact location of the crack on web app by using GPS module.

Vehicle Bridge Interaction in High-Speed Rail Corridors

In this paper, our aim is to establish that Dynamic impact factor (DIF) is not only dependent on the span and type of the bridge but also dependent upon speed of the train and distance between axles of the train as well. Our current code i.e. Indian Railway Standards specify that DIF or Coefficient of Dynamic Augment (CDA) is dependent on span length and type of bridge but it is applicable for design speed up to 160 kmph. For any speed greater than that CDA shall need to be computed as per the dynamic analysis as per available international codes. As mentioned earlier that there is imminent need of high-speed rail network in India due to increase in economic activity, increase in travel choices, improvement in mobility, reduction in congestion and to boost productivity. Our objective of this project is to study dynamic response of a various types of bridges under high speed trains currently being used in India for high speed rail projects like RRTS (Delhi to Meerut and other corridors) and High speed rail project from Mumbai to Ahmedabad to accurately assess the DIF in bridges under the effect of different governing factors (vehicle speed, vehicle load, bridge superstructure type, etc). This study could be beneficial in upcoming projects of high-speed rail as it is our future need. This study is based on the current semi-high-speed rail network i.e. Delhi Meerut Rapid Rail Transit System (RRTS) being constructed and other corridors are to be implemented. Design speed of this project is 180 kmph hence existing IRS codal provision for DIF cannot be used, therefore, dynamic analysis is needed to establish the DIF. Dynamic analysis has been carried out with two types of boggie length i.e. 21.34m and 22.34m. In this project, we have started with the understanding of dynamic analysis by mentioning various codal provisions and parameters influencing the DIF. Subsequently, procedures for computation of dynamic analysis for given superstructure, loading, train type, span, etc have been explained including the modelling part. Last part of this study covers the dynamic analysis of various types of superstructure for given data

The Sendai Framework for Disaster Risk Reduction and Disaster Management Plan of Indian Railways

Sendai Framework for Disaster Risk Reduction 2015- 30 (SFDRR) was adopted by United Nations as a global framework for disaster risk reduction and was signed by member countries. It was adopted as a successor of earlier existing Hyogo Framework for Action 2005- 2015 to advance a common Disaster Risk Reduction (DRR) policy worldwide. In spite of agreement, on the importance of the SFDRR 2015-30, its low implementation at the local level remains a matter of concern. For a developing country like India, SFDRR is of much importance due to a large population vulnerable to all types of disasters. This study examined the extent to which Indian Railways (IR) being the national transporter of India and used by most of Indians, became able to synchronize and adopt SFDRR into its disaster management plan. The study discussed the present disaster management plan adopted by Indian Railways and attempted to identify gaps existing in adoption of the Sendai framework in its risk reduction activities. It is concluded that Indian Railway is able to adopt SFDRR priorities to reduce disaster risks in many of its operational activities except areas like railway construction activities where more actions are to be taken to reduce risk of disasters. The findings will be useful to disaster managers in railway sector as well as other institutions to effectively prepare/modify their disaster management plans so that countries can achieve the disaster risk reduction targets fixed in SFDRR.
