SNCB's Class 12 locomotives were dual-voltage (25000 V, 50 Hz AC and 3000 V DC) electric lomotives built for cross-border service into France.

Class 12 was originally built to work freight and passenger services between Antwerp (via Gent) and Liège (via Namur) in Belgium on one hand and Lille in France on the other.

The introduction of the SNCB Class AM96 electric multiple units displaced them from passenger duty by 1999 but they continued to be used in freight service for 13 more years.

It was then sold to open access operator XTR-System Development in the Czech Republic with an option to buy the entire class.

At midnight on 06/3/2016 they arrived to Česká Třebová and next day continued to ČMŽO at Přerov for overhaul in order to run o SŽDC network.

As of July 2016 at least one of locomotives was painted in corporate livery of CZ Loko, was overhauled for cargo service, this means that its speed was decreased to 120 km/h (75 mph) and train electrical heating was removed.
