ContactWireEstimator is a smart tool designed to help engineers and maintenance teams easily analyze railway contact wire performance. The app brings together all key calculations needed for overhead line equipment in one place. It helps you check contact force variation, wire wear, and contact loss risks quickly and accurately.

You can also estimate wire life, check stress at joints, and evaluate torque or resistance in hardware connections. Each calculator is built for fast, field-friendly use with easy data entry.

Whether you’re inspecting, testing, or forecasting, ContactWireEstimator makes your work simpler and more reliable. Our goal is to support safe, efficient, and long-lasting railway operations.
