Rail Survey

A Railway Track Survey is a specialized type of survey conducted to assess, design, and monitor the alignment, condition, and other critical factors related to railway tracks. Railway Track Surveyors play a vital role in ensuring the safe and efficient operation of railway systems. Their work encompasses various aspects of track infrastructure, from initial planning and construction to ongoing maintenance and improvements. Key responsibilities and features of a Railway Track Survey include: Alignment and Grade Analysis: Surveyors analyze and determine the optimal alignment and grade (slope) for railway tracks, considering factors such as terrain, curvature, and engineering standards. Geodetic Control: Establishing precise geodetic control points to maintain accurate measurements and alignment of the railway tracks, especially in large-scale rail networks. Topographic Mapping: Creating detailed topographic maps that illustrate the surrounding landscape, including elevation changes, water bodies, and relevant features affecting the railway track layout. Construction Layout: Providing accurate survey data during the construction phase to guide the placement of tracks, switches, crossings, and other infrastructure elements according to engineering plans. Monitoring and Inspection: Implementing monitoring systems to assess the ongoing condition of railway tracks, including regular inspections to identify signs of wear, misalignment, or other issues that could affect safety and efficiency. Clearance Analysis: Ensuring that there is adequate clearance for trains, including considerations for bridges, tunnels, platforms, and other structures along the railway route. Crossing and Junction Surveys: Surveying and designing railway crossings, junctions, and interchanges to facilitate smooth transitions between different rail lines and modes of transportation. Track Maintenance Planning: Providing data for the planning of track maintenance activities, such as tamping, ballast renewal, and rail replacement, to ensure the longevity and safety of the railway infrastructure. Safety Compliance: Ensuring that railway track projects adhere to safety regulations, standards, and guidelines set by relevant authorities. Integration of Technology: Utilizing advanced surveying technologies, such as GPS, LiDAR, and remote sensing, to enhance accuracy and efficiency in data collection and analysis. Railway Track Surveyors collaborate closely with engineers, transportation planners, and maintenance teams to optimize railway track design, construction, and maintenance. Their work contributes to the overall safety, reliability, and functionality of railway systems, supporting efficient transportation and commerce.

Railways throughout the world differ dramatically in size, type of operation and the environment in which they operate, yet all are asset-intensive corridors. Geo Adithya asset mapping services provide customers with the information needed to ensure the safe and uninterrupted operation of railway corridors. Recognizing that construction, modification and maintenance of railway corridors add to operating expenses for rail operators, Geo AdithyA has developed a unique combination of technologies to provide cost-effective solutions that assist railway operators in managing their valuable right-of-way assets from city centers to remote rural areas.Geo AdithyA Rail Corridor Observation and Reporting program use leading-edge technology to gather field data during regularly scheduled airborne or rail car surveys. High-resolution digital images and other sensors acquire continuous coverage of the right-of-way, providing updated geo-referenced datasets from every mission. Once processed and compared to previous data, our fast and automated change detection software highlights areas of concern for more detailed analysis, providing our clients with the most recent dataset to maintain the currency of their in-house or web hosted GIS.

Railway surveying is focused on providing and managing the spatial information required for the design and maintenance of railroad infrastructure. Railway surveying requires the use of rigorous surveying techniques, technical standards, and design principles that allow tracks and associated infrastructure to be designed, built, and maintained so that trains can move safely at an optimum speed over the system.

Road and Railway Engineering survey: * feasibility study, new route selection, preliminary and final location survey and land acquisition. * establishment of gps stations. * carrying out closed traversing along the highways using electronic total station and distribution of closing errors with least square method. * carrying out detailed topographical survey for all surface features, ground levels,longitudinal and cross section profiles and plotting the drawing in autocad format. * preparation of detailed project report and drawings. * setting out of coordinates during the time of civil construction and taking as built survey of the same and submitting to the client.
