A 95-ton steam-shovel at work in Panama Canal. This shovel has a capacity of about 5 cubic yards and when the dipper is full of mixed rock and earth it weighs about 8 tons, which is about 5 two-horse cart loads. One of these shovels has taken out over 8,000 tons of material in a day.
Loading a dirt train on the Panama Canal. The large dump train is composed of about 25 cars and the average load is about 725 tons. The cars are dumped by compressed air and a whole train is cleared in about 30 minutes.
