Milliseconds to decide
A spraying train in motion leaves only milliseconds between detecting a weed spot and firing the correct spray sector — the whole pipeline has to be real-time, deterministic and safe.
Square21Weed recognition on a moving train: onboard cameras detect weed spots in milliseconds and the system triggers herbicide spraying only where weeds actually grow. Targeted spraying saves up to 60–80% of chemicals and water compared to blanket treatment — better for the environment and the budget.
G&G Kft. is a Hungarian family-owned company that has performed railway weed control across Europe and the USA since the 1990s, building and operating specialist spraying trains. Their latest-generation vehicles pair train-mounted cameras with intelligent, sector-by-sector spraying control.
A spraying train in motion leaves only milliseconds between detecting a weed spot and firing the correct spray sector — the whole pipeline has to be real-time, deterministic and safe.
Lighting, weather, seasons and track environments vary wildly. Detection has to stay accurate on gravel, concrete and vegetation-covered lines alike.
Train-mounted cameras feed a real-time recognition pipeline that classifies weed coverage and drives independent spraying sectors — chemicals are applied only where the camera actually saw weeds.
Spraying only where needed cuts herbicide and water use by up to 60–80%, keeping tracks safe while dramatically reducing the chemical load on the environment.
One conversation is enough to tell whether we’re the right partner.
