DropperSolverPlus is a app to help engineers and technicians working with overhead line systems. It brings together key railway catenary calculations in one easy-to-use platform. From finding the right dropper forces and lengths to checking sag, uplift, and tension, the app makes complex tasks quick and clear.

It also helps analyse stagger deviation, registration arm angle, and clearance to structures. With built-in tools for temperature effects, wave speed, and insulator design, users can get accurate results anytime.

DropperSolverPlus saves time, reduces errors, and supports better decision-making in the field. Our goal is to make catenary analysis easy, fast, and reliable for everyone.
