Since 2012, the EF81 cars belonging to JR Freight Toyama Locomotive Depot have had the number 600 added to their current numbers to indicate the difference in safety equipment compared to the passenger company's 0-series cars. The 600-series cars were used to pull freight trains on the Japan Sea Trunk Line until 2016, after which some were transferred to the Kyushu region and continued to be used there. All of the cars have now since been retired.
