| Abstract | This paper presents preliminary results towards an automated monitoring system for the quality assessment of insulated rail joints based on axle box acceleration (ABA) measurements. ABA signals from all the wheels of the measuring train (trailing and leading wheels, right and left rails) are processed to extract those characteristics that better represent the quality and the state of the insulated joint. We compared the responses of different insulated joints in good condition, and three cases of joints in poor condition with visible surface degradation, fastening damage and damage to the insulation layer. Different indicators are used to classify the joint condition, the most relevant being the maximum ABA response, and some frequency bands in the ABA power spectrum. Track inspections and hammer tests were performed to collect validation data of the studied insulated joints. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
