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.^[1] 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.^[2]
