Rail traffic in Rotterdam Port, Europe's busiest, was disrupted recently by the derailment of a container car carrying inflammable cargo, the operator said.

"Traffic is partially disrupted. Diesel engines can run while electric engines cannot run," said Azra Drost, a spokeswoman for a Keyrail, a commercial freight operator.

No one was hurt in the accident and no hazardous materials were on the train, she said, adding it was unclear when shipments would resume.

Every day some 200 trains run to and from the port of Rotterdam carrying everything from frozen fish to computers, coal and chemicals.

Rotterdam is a major transit point for commodities, including oil and grains, and manufactured goods. It is also the biggest port for iron ore for the German blast furnaces in the Ruhr region which supply the German auto industry. (Reuters)
