Thank you for the pictures Johan. Is that a stock piece or did you build or modify it beyond your usual excellent weathering job?
Flysplanes-Playtrains, have you tried adding weight over the wheels that derail. I believe many of the K-line switchers have a tendency to derail because the torque of traction tire drive wheels on the in-board axles of the the trucks tend to to cause the trucks to rear up a little causing the forward axle to derail at track imperfections. A little weight over the forward axle may help.
