Not freed up until December or January. The Edmonton cars are even more over-sized as they have to sit on a steel structure that is longer than the flatcar.Pickup isn't speedy at Thunder Bay either, but that's not surprising either. There is paperwork that Bombardier has to do as shipper, and then more paperwork that the railway has to do as the cars are considered dimensional (ie oversize) loads. The Millhaven cars will be interchanged so both CP and CN will have to do paperwork, and coordinate a little more than they might for a boxcar of peaches. They may get the kinks out after a few cars are shipped.
One of the transporters in the Toronto-Thunder Bay cycle appears to have been freed up and handed over to CN. I'm guessing that it may be on its way to Millhaven. I don't know whether the two transporters that were delivering KW cars are now free and clear from that duty yet.
