It appears Piko now has developed also a coupler hook for us 3 railers or users with european style couplers. I skipped the SP9000 before for having knuckle couplers only. It is unclear however whether the couplers will be part of the delivery of the new locos, and whether they are really compatible with the Carlier SP9000s. They also appear to have a rather large coupling distance and some strange bends that do not give confidence in pulling power. If anyone has more information on this it would be nice!
