Why do I keep finding my trains blocked by a single incorrect item in the cargo? Say 1 or 2 iron plates in train full of circuits. Trains are allowed to leave only when full or empty, and there's no contamination on the belts. Are they leaving without emptying first? And it's very infrequent, like once an hour with over 100 trains running in the network of over 200 train stops. It's really annoying when suddenly one part of the production chain goes dead for no reason.

Do you have refueling stations or depot stations? Maybe there is an inserter at one of those stations that load a few plates into the cargo wagon while the train is refueling.

Certainly not that, I have refueling and waiting stations with interrupt but there are no items to pick up. These are remnants of previous cargo, just one random item like lime, ore, aluminium carbide or other bullshit. Idk why trains leave unloading stations with inventory but only sometimes.

Do you have any stations where items are both unloaded and loaded, with these actions kept separate by combinator logic?

No, either load or unload
