There’s also “leaves on the track”, my personal favourite. Sometimes I struggle to believe trains were invented in the UK!

This one,albeit sounding funny,is a pretty serious issue: leaves get crushed under the weight of a train and eventually form a teflon like film on the tracks, which makes it very slippery. Not an expert in this area,so no idea how it's dealt with in various countries.

My favourite is: the carriage is deflated. People couldn't stop laughing when told so, but what it meant in reality is that the support cushions deflated and the carriage can't have passengers on board.

Most systems with wet leaf problems use sand dispensers for added traction.

And there’s the rub. Is that network rail’s problem, or the operator’s? Network rails’s rails... operator’s train wheels, leaves in the middle. The leaves are undefined, and are therefore probably nobody’s problem but the passengers’.
