AnsaldoBreda has threatened to take legal action against NS after the Dutch operator officially announced the cancellation of its order for 16 Fyra trains.
NS confirmed the cancellation last week, having already made clear its plans not to proceed with the high-speed V250 after services were cancelled between Amsterdam-Brussels in January over safety concerns.
The Italian train builder had unsuccessfully attempted to block SNCB from recouping bank guarantees worth 37 million euros for undelivered trains.
AnsaldoBreda now says it plans to take legal action against NS over the cancelled order, which is worth around 300 million euro.
In a statement, the company said: “AnsaldoBreda had immediately given the assurance on the reliability of the V250 also exhibiting, certificates formal customer appreciation for the work done, showing that there are no technical reasons to justify the withdrawal from circulation of the train.
“AnsaldoBreda, considering unacceptable considering instrumental and the decision taken, will take any necessary legal action designed to protect their interests.”
