Railway Survey is one of the most critical steps in the successful planning, design, and execution of railway projects. It involves detailed study and measurement of land, terrain, and natural features to determine the most suitable alignment for railway tracks and associated infrastructure. Using modern surveying technologies such as GPS, Total Station, Drone Mapping, and GIS, highly accurate data is collected to support decision-making and ensure precision in every stage of railway development.

A professional railway survey not only helps in route selection and track alignment but also plays a vital role in planning bridges, tunnels, stations, and crossings. It minimizes risks, reduces construction costs, and ensures safety by providing engineers and planners with reliable information about gradients, curves, soil conditions, and land acquisition requirements.
