"a period of in-service trials"
Thats the official line from IE as of today.
So its a case of catch it if you can. As soon as we have exact times we'll endeavour to notify those interested. They look great (except for the freight loco at one end

) and like many others, Im looking forward to using them.
Please note P11 will be reviewing this new stock on the basis of what they offer the customer in terms of comfort and on board facilities. More technical reviews from board members can be posted at will.
