RailStatic

A rail static weighbridge system that weighs a whole rake of wagons, wagon by wagon.

VB.NETWinForms.NET Framework 4.8Serial / RS-232
RailStatic
Overview

RailStatic is a Windows desktop application built to weigh railway wagons on a static rail weighbridge, typically at a mining or industrial site. It interfaces directly with physical weighbridge load-cell indicators over serial ports, capturing Gross, Tare, and Net weights for each wagon as a full rake (train) rolls across the bridge — then stores, reports, and prints the results from a single operator station.

The challenge

Weighing an entire rake wagon by wagon is repetitive, timing-sensitive work: readings have to be pulled from industrial load-cell indicators at exactly the right moment for each wagon, recorded accurately against the right train, and turned into printable records — reliably, from one station at the weighbridge.

What we built
01

Rake-based wagon weighing

Captures each wagon’s weight in turn as a rake passes over the static bridge, keeping every reading tied to its train so a full trainload is recorded in one continuous operation.

02

Gross / Tare / Net capture

Records Gross, Tare, and Net weights for every wagon, computing net load automatically from the captured figures.

03

Persistent records

Every weighment is stored, so completed and historical wagon and rake weights can be retrieved and reviewed later.

04

Reporting & ticket printing

Generates reports and prints weighment tickets directly from the operator station for record-keeping and dispatch.

Under the hood
01

Native Windows desktop app

A VB.NET WinForms application on .NET Framework 4.8, running on the operator’s Windows PC at the weighbridge — no browser or server dependency.

02

Serial load-cell interfacing

Talks to weighbridge load-cell indicators over RS-232 serial ports, reading the same signals that drive the physical weight display.
