NSB El 15 is a class of electric locomotives which are now operated by the Norwegian company Grenland Rail. The locomotives were originally built for the Norwegian State Railways (NSB) in 1967 to replace the NSB El 3 and NSB El 4 engines on Ofoten Line. The main task there is to pull heavy iron ore freight trains, and the El 15 is the most powerful engine which NSB has ever used.[ citation needed ]

After the electrification of Ofotbanen in 1923 NSB had been using El 3 and El 4 stock on the line. But in the 1960s these were getting worn out, and NSB decided that it needed to get new stock. NSB first acquired the El 12 stock parallel to the Swedish acquisition of the Dm3 locomotive. But unlike Statens Järnvägar, NSB chose to instead buy a newer technology locomotive from ASEA, based on the Romanian CFR 060 EA. Thus NSB managed to get the same power out of their two-engined El 15s as the Swedish got out of their three-engined Dm3s. Since the locomotives were to be operated in pairs, NSB considered only installing driver cabins on one end, but chose in the end to install them on both ends to allow the locomotives to operate more flexibly, including allowing them to operate passenger trains. The locomotives were numbered 152191 to 152196.

In 1996 the operation of the ore trains was taken over by Malmtrafik, owned by NSB, SJ and LKAB, the owner of the mines. The new company ordered 18 new IORE locomotives from Bombardier and in 2004 the ageing engines were sold to Hector Rail. After deliveries of new locomotives to Hector Rail in 2019, they were taken out of service and were sold to the Norwegian company Grenland Rail in 2020, where they have been painted dark-blue and reclassified as El 15.

<span class="mw-page-title-main">NSB El 17</span> Norwegian State Railways class of twelve electric locomotives

The NSB El 17 is a class of twelve electric locomotives built by Thyssen-Henschel and Norsk Elektrisk & Brown Boveri (NEBB) for the Norwegian State Railways (NSB). The class was built in two batches, the first delivered in 1982 and numbered 2221–2226, and the second delivered in 1987 and numbered 2227–2232. The traction system of the El 17 was based on the DB Class 120 of Germany and were among the first in the world to feature three-phase asynchronous motors. The units were ordered to be used on the intercity Bergen, Dovre and Sørland Lines, but were plagued with technical faults. The unreliability and lack of sufficient power forced NSB to instead use them in the regional Vestfold and Gjøvik Lines. With the delivery of the El 18, the first series was retired or used as shunters. The second series has been used on the Flåm Line since 1998.

Today it is operated as a heritage railway and is the world's oldest railway running on its original alternating current electrification scheme, using 6.6 kV 25 Hz AC. It was built to transport pyrites from the mines at Løkken Verk to the port at Thamshavn, as well as passengers. There were six stations: Thamshavn, Orkanger, Bårdshaug, Fannrem, Solbusøy and Svorkmo. The tracks were extended to Løkken Verk in 1910.

Iore, often stylized IORE, is a class of 34 electric locomotives built by Adtranz and its successor Bombardier Transportation for the Swedish mining company LKAB's railway division Malmtrafik. The class is a variation of Adtranz's Octeon modular product platform, thus related to Bombardier's later TRAXX platform. The locomotives haul iron ore freight trains on the Iron Ore Line and Ofoten Line in Sweden and Norway, respectively. The 8,600-tonne 68-car trains are hauled by two single-ended Co′Co′ locomotives, each with a power output of 5,400 kW (7,200 hp). Each operates with 600 kilonewtons tractive effort and has a maximum speed of 80 km/h (50 mph). Delivery of the first series of 18 locomotives was made from 2000 to 2004, and they replaced some of the aging Dm3 and El 15 units. In 2007, eight more vehicles were ordered, with production to be completed by 2011, by which time, another four double units were ordered. These units were scheduled to be delivered from 2013 to 2014.

<span class="mw-page-title-main">Timeline of railway electrification in Norway</span>

The Norwegian railway network consists of 2,552 kilometers (1,586 mi) of electrified railway lines, constituting 62% of the Norwegian National Rail Administration's 4,114 kilometers (2,556 mi) of line. The first three mainline systems to be electrified were private ore-hauling lines. The Thamshavn Line opened in 1909, and remained in revenue use until 1973, after which it was converted to a heritage railway. It is the world's oldest remaining alternating-current railway and the only narrow gauge railway in the country to have been electrified. It was followed by Norsk Transport's Rjukan and Tinnoset Lines two years later, and Sydvaranger's Kirkenes–Bjørnevatn Line in 1922. The Norwegian State Railways' (NSB) first electrification was parts of the Drammen Line in 1922 and the ore-hauling Ofoten Line, which connects to the Iron Ore Line in Sweden, in 1923. The use of El 1 locomotives on the Drammen Line proved a large cost-saver over steam locomotives, and NSB started electrifying other lines around Oslo; from 1927 to 1930, the remainder of the Drammen Line and the continuation along the Randsfjorden and Sørlandet Lines to Kongsvinger were converted, along with the first section of the Trunk Line. In 1935, the Hardanger Line became the first section of new NSB track to be electrified. From 1936 to 1940, NSB electrified the Østfold Line, as well as more of the Sørland Line and the Bratsberg Line, connecting all electric lines west of Oslo.

The Norwegian railway network consists of 2,552 kilometers (1,586 mi) of electrified railway lines, constituting 62% of the Norwegian National Rail Administration's 4,114 kilometers (2,556 mi) of line. In 2008, electric traction accounted for 90% of the passenger kilometers, 93% of the tonne kilometers and 74% of the energy consumption of all trains running in Norway, with the rest being accounted for by diesel traction.
