In the late 2010s Bombardier has been beset by software and quality issues on a series of so-called "legacy" contracts in Europe and the U.S., forcing Bombardier to incur additional costs and pay late-delivery penalties. This includes high profile issues in contracts for the New York City’s MTA, Germany’s Deutsche Bahn, Switzerland’s SBB and London Overground. Analysts speculate that since acquiring Adtranz, a company twice the size of Bombardier at the time, Bombardier has created a series of organizational problems that took years to resolve.
