On May 12, 2015, an Amtrak "Northeast Regional" train from Washington, D.C. bound for New York City derailed and wrecked on the Northeast Corridor in the Port Richmond neighborhood of Philadelphia, Pennsylvania.
 Of 238 passengers and 5 crew on board, 8 were killed and over 200 injured, 11 critically.
 The train was traveling at 102 mph in a 50 mph zone of curved tracks when it derailed.
The 1987 Maryland train collision occurred at 1:30 pm on January 4, 1987, on Amtrak's Northeast Corridor main line in the Chase community in eastern Baltimore County, Maryland, United States, at Gunpowder Interlocking, about 18 mi northeast of Baltimore.
 Amtrak train 94, the "Colonial" (now part of the "Northeast Regional", from Washington, D.C., to Boston), crashed into a set of Conrail locomotives running light, and which had fouled the mainline.
 Train 94's speed at the time of the collision was estimated at about 108 mph .
 Fourteen passengers on the Amtrak train were killed, as well as the Amtrak engineer and lounge car attendant.
The Taunus Railway (German: "Taunus-Eisenbahn") is a double-track electrified railway line, which connects Frankfurt and Wiesbaden, Germany.
 It is 41.2 km long and follows the course of the Main on its north side, in some parts quite close to it.
 Its first stage was opened in September 1839 and is thus the oldest railway line in the German state of Hesse and one of the oldest in Germany.
 Today it is used by RegionalExpress trains between Frankfurt and Wiesbaden and the trains of line S 1 of the Rhine-Main S-Bahn between Frankfurt-Höchst and Wiesbaden.
 Between Frankfurt Hbf (Frankfurt central station) and Frankfurt-Höchst, they run on the former Hessian Ludwig Railway line.
The Sinhŭng Line is an electrified railway line of the North Korean State Railway running from Hamhŭng on the P'yŏngra Line to Pujŏnhoban on Lake Pujŏn.
 Between Hamhŭng and Sinhŭng, a distance of 40.9 km the line is standard gauge, but the remaining 50.6 km from Sinhŭng to the terminus at Pujŏnhoban is narrow gauge; the narrow gauge section is also electrified.
 There is also an electrified narrow-gauge branch, the Sŏho branch, from West Hamhŭng to Sŏho.
 Though primarily an industrial railway connecting to the Pujŏn River hydroelectric power plant, it also plays an important role in passenger transportation in the region.
 There is a 550 m section between Songhŭng and Pujŏllyŏng that is cable-hauled.
The Norwegian railway network consists of 2552 km of electrified railway lines, constituting 62% of the Norwegian National Rail Administration's 4114 km 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 in 1923, which connects to the Iron Ore Line in Sweden.
 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 Dill Railway (German: "Dillstrecke") is a 73 km-long double-track electrified railway line, which runs from Giessen in Hesse to Siegen in North Rhine-Westphalia.
 Until 2002 InterRegio trains operated the connection to Düsseldorf, Norddeich, and Münster.
 Nowadays the line is only worked by regional trains, including diesel multiples of the DreiLänderBahn, but there is one exception.

 The southern section between Haiger and Gießen was built by the Cologne-Minden Railway Company in 1862 as part of its line from Deutz and is one of the oldest railways in Germany.
 The section from Haiger to Siegen was opened in 1915 by the Prussian state railways.
Railway line 132 is a double-track, electrified railway line running across the Silesian, Opole and Lower Silesian Voivodeship, and as such serving as the main railway artery between Bytom and Wrocław.
 Between Opole and Wrocław, the railway line is part of the E-30 Pan-European railway corridor, whilst between Pyskowice and Opole, part of the CE-30 line.
 The lines form the Third Pan-European railway corridor.
 Between Zabrze and Pyskowice, the railway line has been deconstructed.
The Eastern Railway (German: "Ostbahn" ), formerly also known as the Vienna-Raab railway (German: "Wien-Raaber Bahn" ), is a two-track, electrified railway line that runs from Vienna towards Hungary.
 The name "Eastern Railway" refers to several branches of the line as well.
 The previous western terminus of the railway line in Vienna, Wien Südbahnhof, has been replaced by the new Hauptbahnhof, which allows for continuous east-west traffic and connects the Eastern Railway directly to the Western Railway and Southern Railway.
The Northeast Corridor (NEC) is an electrified railway line in the Northeast megalopolis of the United States.
 Owned primarily by Amtrak, it runs from Boston through Providence, New York City, Philadelphia, and Baltimore to Washington, D.C..
 The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States by ridership and service frequency as of 2013.
 Branches to Harrisburg, Pennsylvania, and Springfield, Massachusetts, though not considered part of the Northeast Corridor, see frequent service from routes that run largely on the corridor.
