The delivery of GB Railfreight's new 66752-756 has suffered a small delay. Yesterday (June 30), the ship carrying the five new locos on board, had not yet left the US. This means that the target of July 7-10 will not be met. The week after has been given as very provisional estimate.
Update: On July 1, the HR Resolution has started its journey towards the UK from the port of New York, after having sailed down the Hudson river. One can track the ship here: link.
