The train company, owned by Virgin Rail Group, has asked passengers to take more care when using the bathrooms on board their transport, because the number of inappropriate items getting flushed down the toilet is causing them to become blocked at a rapid rate.
According to Gizmodo, it costs Virgin over £180,000 a year to fix toilets that have been broken unnecessarily, just from people flushing things they shouldn't.
The most common culprit is wet wipes, but some more bizarre items include underwear - with one case even seeing a woman flush away her bra - wedding rings, nappies, glasses, and a scarf.
Michael Jacks, Head of Fleet and Engineering at Virgin Trains, said: "It did make us smile when we found the bra as it's not something you would expect to find.
"But it does highlight a very serious issue, and one that greatly impacts on our customers. Bins are provided, and we would remind our customers to follow the 3Ps of flushing. Only pee, poo and paper should be flushed down any toilet."
Virgin says four toilets each day are taken out of use by inappropriate flushing.
