Hi All, I have created a scenario - Rugby Freight for the WCML South route which I published a couple of years ago. I've been trying to update this recently, and one of the updates is to decouple half the consist at Wembley yard before proceeding to Willesden. Unfortunately when I attempt to decouple the consist immediately derails. The error message says AI derailment even though its the player consist. I've noticed other threads that discuss derailment when coupling, so I wondered if its an issue with the length of the flats in the config. I've tried decoupling at the very start of the published scenario with the same results. Can anyone provide any guidance please that suggests why this is happening? Thanks.
