The first multi-system TRAXX unit that could operate under AC and DC electrified catenaries, SBB Re484 001, was introduced at the same time 185 561 was introduced as demonstrator locomotive for the F140 AC2 type.
In addition to the 15 kV/16.7 Hz and 25 kV/50 Hz AC supplies, the new model could also be operated under 3 kV DC overhead electrification.
Later models also supported a 1.5 kV DC supply.
This locomotive for SBB was also the first TRAXX variant with individual axle control in place of individual bogie control.
The general type name given by Bombardier was TRAXX F140 MS.

Apart from the different pantographs, electrical systems for DC operation, the F140 MS types are identical to the contemporary dual voltage versions.
However, under 1.5 kV DC, the maximum available power is limited to 4.0 MW, although this does not affect the maximum tractive effort, which is limited by other factors.
As a consequence of the additional equipment required, the locomotives weigh approximately 1 tonne more than their dual voltage relatives.

The locomotives are designed for cross border operations; the addition of 1.5 kV and 3 kV DC operability potentially allows the locomotives to operate in Poland and Italy.
In practice the delivered locomotives were used for work into Switzerland and Italy, and equipped with either the Italian safety system SCMT or ETCS.

Post 2006 many more of these multi-system locomotives were produced, this time with some for use in the Benelux countries, as well as France and Poland, with further units being produced for Swiss/Italian traffic.
In Poland, locomotives used by PKP Cargo have been designated as the EU43 class.
Units hired from Alpha Trains cargo to SNCB (Belgium) have also received the class number SNCB Class 28
In July 2018, Bombardier introduced the third generation of TRAXX multi-system locomotives, named the MS3, which in addition to carrying over compatibility with the four electrification systems introduced an on board engine to enable travel over short distances of non-electrified track.
