South African Class 5M2
South African Electric Multiple Unit class
The Class 5M2 and Class 5M2A are electric multiple units that provide commuter rail services operated by Metrorail in the major cities of South Africa. The original Class 5M2 trainsets were built for the South African Railways by Metro-Cammell between 1958 and 1960. Most of those in use today, however, are of Class 5M2A, built to the same design by Union Carriage & Wagon (UCW) from 1962 to 1985; a total of 4,447 coaches were built by UCW.
A programme began in the 2000s to rebuild the trains, which were subsequently designated Class 10M3, 10M4 and 10M5. Class 5M2A coaches were stripped down to the underframe, which was then used as the base for the Class 10Ms.
Specifications
The Class 5M2s operate on the 3 ft 6 in (1,067 mm) Cape gauge track that is standard throughout Southern Africa. The motor coaches draw 3,000 volt direct current from an overhead pantograph; they have a power output of 925 kilowatts (1,240 hp) and produce 158 kN (15.9 LTf; 17.8 STf) of tractive effort. The maximum speed of a 5M2 trainset is 100 kilometres per hour (62 mph). A motor coach can carry 56 seated and 110 standing passengers, and has a tare weight of 60 tonnes. A trailer coach can carry 52 seated and 149 standing passengers, and has a tare weight of 30.5 tonnes (30.0 long tons; 33.6 short tons).
This brief starts where responsible research should: with the source description of “South African Class 5M2” as south African Electric Multiple Unit class. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as south African Electric Multiple Unit class. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 12, 2025. The linked authority identifier is Q7565544. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1958, 1960, 1962 and 1985.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
