Is there a Stadler issue ? So we skip Class 67 just as we skipped over BR 120 in Germany ... but do we have to wait for Class 68 to go to museum nuclear flask moves ? Oh, but those are done push-pull with what kind of wagons forming the sandwich ? Do any Class 68 move military assets ? Through the tunnel to Calais ? This is not a suggestion ... i'm only asking while i wait for my fast SSD drive to slowly, carefully, cautiously, load TSW5 onto an old PS5.
Rivet posted Class 68 WIP as a April Fool prank a year or two ago, later deleted it. So maybe never or wait for an announcement if there is one.
