The longest road train ever assembled was 1,018.2 m (3,340 ft) long and consisted of 79 trailers with a combined weight of 1,072.3 tonnes (2.364 million lb). It was pulled a distance of 8 km (4.9 miles) by a Kenworth C501T truck driven by Australia's Steven Matthews.
There are 17 trucks with 3 trailers and 2 decks per trailer. Therefore there are 102 decks of cattle and there would be approximately 28 cattle per deck. This totals 2,856 head of cattle. The cattle will weigh approximately 500kg each.
