 Between 2002 and 2005, all of the FER V 200.0 locomotives underwent refurbishment in Zagreb which included replacement of the existing Maybach or Mercedes engines with Caterpillar D3508 V8 engines, capable of 810 kW, and modern digital engine control systems in place of the original Brown-Boveri electro-mechanical control system.All the FER locomotives are fitted with the Voith L306r transmission.The locomotives were painted in a rather garish Italian tri-colour (green-white-red) livery.
