A lineup of major law firms including Cleary Gottlieb Steen & Hamilton and Freshfields Bruckhaus Deringer are advising on the €6 billion sale of transport giant Bombardier's rail operations. 

Alstom, the Paris-based maker of the TGV bullet trains, is set to take on the arm. The cash-and-stock purchase is subject to antitrust approval by European regulators; the EU's competition directorate scuttled a proposed rail merger between Alstom and Siemens of Germany in 2019. 

Cleary Gottlieb Steen & Hamilton is advising Alstom, a longtime client, with a team led by partners Pierre-Yves Chabert in Paris on corporate and mergers and acquisitions, Anne-Sophie Coustel in Paris on tax, and Antoine Winckler in Brussels on antitrust.
