The Dr16 is a class of diesel-electric locomotives used by VR (Finnish Railways). The 23 locomotives have a single, off-centre cab. Their nickname is "Iso Vaalee" (Big Blonde). They are presently mainly used on heavy freight services in northern Finland; their main passenger duty is the haulage of trains on the non-electrified line between Kemi and Kolari in Lapland. Dr16 locomotives were also used extensively on the line between Oulu and Rovaniemi, prior to the completion of the electrification of the line in 2004.
