Miners including Glencore Plc and Drummond Co. can continue transporting coal at night along Colombia’s main railway until October 31, making it easier to send exports to markets in Europe.

A court in northern Colombia extended the lifting of transport restrictions between 10.30 p.m. and 4.30 a.m. on the Fenoco coal railway until the end of the month, according to a court document sent by e-mail. The restrictions had originally been lifted only for the first 15 days of October. A regional authority requested the extension to continue testing noise levels along the railway.

Colombia banned night transport along the railway in February following protests by local residents. That cut capacity by 25 percent, equivalent to about 15 million tons of coal on an annualized basis, Fenoco President Patrick Ross said in February.

The railway connects coal mines in northern Colombia with Caribbean ports. Coal is Colombia’s biggest export after oil.
