Finally got around to it...I just followed the directions on the Kato website to modify the pilot coupler of the E8/9 to a longer shank (provided by Kato). Works like a champ so far. That extra few millimeters of shank allows the usual tail-to-tail running of the diesels. When I would run them without this longer shank, the first turn would derail the lead passenger car since the pilot coupler couldn't swing as far left or right as needed. For those who haven't modified their E8/9's...look for the extra coupler buried in the packing of the clear plastic box (I just discovered mine today after owning the things for months now...call me Mr. Observant). Follow the directions located on the Kato website and make sure you have two tweezers handy to hold the tiny and almost weightless parts. Expect to drop all the parts used at least three times. But keep at it cause it's worth it. Pictures to follow soon!:thumb:
