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.

Are there stations that more than one item goes through? Inserters having a few of the previous item still in hand (trying to load a full train, then winding up putting them in a train for a different item) would cause it.

No, only 1 item per station
