Class 373

The British Rail Class 373 was the sole train used by Eurostar from 1994 to 2015, before the new Class 374 units began to be introduced.

The Class 373 is part of the TGV family of trains. It uses an electric overhead system on all parts of the system from London to France/Belgium. However, it previously used a third-rail system within the United Kingdom, before HS1 and St Pancras International opene. It is also known as the 'TransManche Super Train. '

Besides Eurostar, the French low-cost rail service IZY has begun using a 373 Unit.

Other operators besides Eurostar and IZY have used Class 373 or TGV TMST's in the past.

The British railway company GNER used NOL (North of London) sets on the East Coast Mainline between 2000 and 2005.

The French rail operator SNCF used the NOL sets after GNER's lease ended and well as three of their own "Three Capitals" sets in France on domestic services until October 2014.
