The rumours that Colas Railfreight is to evaluate PowerHaul demonstrator 70099 are getting stronger. An order for ten of these locomotives would be considered by the British rail operator. If the order gets the go-ahead, then Colas Railfreight will be the second operator to order the PH37ACmi.

Freightliner, the launching customer of the PH37ACmi, has 19 units in service at this moment (70012 was dropped onto the docks). As the initial order was for 30 locomotives, it's unclear now if Freightliner will take delivery of the remaining units in the future or if Colas will take over this batch of ten.
