Quick question for anyone who has purchased the Kato E8 A/A unit set...I tried running them in a more classic "end to end" configuration and joined with the Kato passenger set, the lead passenger car would derail in the first turn every time. It seems to me that the pilot coupler on the trailing "A" unit doesn't move to the right and left far enough for the passenger car truck to stay on the track. Did anyone have this problem too? I noticed what looks like a longer shank coupler added to the Kato box under the packing...I'm guessing this might just be the reason? If anyone that has run into this problem and fixed it...pass on your valuable knowledge please...I sure would like to get this train moving around the layout. BTW, when you hook the diesels to the passenger cars with both diesels facing forward, the passenger cars never derail, again cementing my thought that the pilot coupler is too short and limits the angle causing the derailment. Thanks everyone!!!
