căile ferate române (cfr), romania's national railway worker, is one of the largest users of the siemens desiro trainsets. cfr, which is right now undergoing modernisation, has bought many desiro trainsets and uses them for all types of train: ""regio", "interregio" and "intercity" inter-city services, but mostly on its "interregio"" express trains. there was some criticism of the use of desiros for cfr's long-distance services because they were thought to be uncomfortable. cfr has recently refitted them, and is now using desiros mostly on its medium and short-distance routes.
