[[File:VT 11.5 in Munich (1970).jpg|thumb|[[Deutsche Bundesbahn|German]] [[DB Class VT 11.5]] [[Diesel multiple unit|diesel trainset]] that was used in TEE service until 1972 at [[München Hauptbahnhof]] in 1970]]
Initially, the system was a completely [[Diesel engine|diesel]] network. Because of the many different kinds of electrical specifications (voltages and current types – [[alternating current]] and [[direct current]]) used in the different countries it was thought at that time that use of [[Diesel locomotive|diesel-hauled]] trains or [[Diesel multiple unit|diesel multiple-unit trainsets]] would greatly speed up border crossing. Moreover, at that time many border crossing sections were not yet [[Overhead lines|electrified]]. The German [[Deutsche Bundesbahn|DB]] built the [[streamliner|streamlined]] [[DB Class VT 11.5]], while the [[Swiss Federal Railways]] (SBB) and the Dutch [[Nederlandse Spoorwegen|NS]] developed the [[SBB-CFF-FFS RAm TEE I and NS DE4|RAm / DE]], both diesel trains.

[[File:TEE L'Oiseau Bleu, Brussels, 1979.jpg|thumb|An [[SNCF CC 40100]] with the Brussels–Paris ''L'Oiseau Bleu'' TEE in 1979. By the 1970s most TEEs were [[Electric locomotive|locomotive]]-hauled, rather than [[Multiple unit|self-propelled]] trainsets.]]
However, the creation of the international TEE network provided impetus for the development of special electric [[Electric multiple unit|trainset]]s and [[electric locomotive]]s, capable of operating at two or more different voltages.<ref name="second-demise"/> The DB used the {{Convert|160|km/h|mph|abbr=on|adj=on}} [[DB Class E 10|E 10.12]] and the {{Convert|200|km/h|mph|abbr=on|adj=on}} [[DB Class 103]], among other types. The SBB developed its [[SBB RAe TEE II|RAe TEE II]] electric trainset, which was designed for four different [[railway electrification system]]s, and this type entered service in 1961. [[National Railway Company of Belgium|Belgian National Railways]] introduced its Type 150 locomotives (now called [[SNCB Class 15|Class 15]]) in 1962, capable of handling three different voltages, followed by the four-voltage Type 160 ([[SNCB Class 16|Class 16]]) in 1966 and [[SNCB Class 18 (Alsthom)|Class 18]] in 1973.<ref name="second-demise"/> Meanwhile, France's [[SNCF]] also developed and introduced ten quadruple-voltage locomotives, its [[SNCF CC 40100|Class CC 40100]], between 1964 and 1970.<ref name="second-demise"/>

By 1975, all but two (''[[Arbalète (train)|L'Arbalète]]'' and ''[[Bavaria (train)|Bavaria]]'') of the 43 TEE trains were electrically powered, and most were locomotive-hauled.<ref>''[[Thomas Cook European Timetable|Thomas Cook Continental Timetable]]'' (June 1–30, 1975 edition), p. 69.
