NSB Class 66 (Norwegian: NSB type 66) was a three-car electric train used by the Norwegian State Railways for express trains on the Østfold Line to Halden and Gothenburg, and the Sørlandet Line to Kristiansand and Stavanger. The four multiple units were built by Skabo Jernbanevognfabrikk, with motors from Norsk Elektrisk & Brown Boveri, and delivered in 1945–46. They were originally named Class 106, but this was changed in 1956. The trains received the numbering BFM 66.01–04, B 66.31–34 and BS 66.61–64.
The class was the electric counterpart of diesel Class 88. With a power output of 474 kW (636 hp), it was the first train capable of 120 kilometers per hour (75 mph) in Norway. One of the Class 66 trains was involved in the Hjuksebø train disaster in 1950. Since 1967, the trains served on the Vestfold Line. The Class 66 was retired from service in 1977. BFM 66.01 has been preserved by the Norwegian Railway Museum.
