Things you expect to find on a train include: litter, old newspapers, people talking loudly on their phone, chewing gum on the seats.

Things you don’t expect to find on a train probably includes eight tiny toads.

However, this is exactly what one good Samaritan found on a journey from London to Folkestone.

The small creatures were discovered left behind on a carriage, in a plastic box, placed in a carrier bag.

It is not known who found them, but they were taken to the Montgomery Veterinary Clinic, based on the Evegate Business Park, in Smeeth, which specialises in small and exotic animals.

Staff identified them as fire bellied toads, about an inch in size, suggesting they are quite young.

Watch: Toads on a train

Veterinary nurse Lucy Toombs said: “At first glance they seemed healthy.

“They didn’t appear injured or malnourished.

“They had a damp towel in the box, which would have helped them keep moist.

“They are leaping around happily and eating.”

The nurse said a train was a strange place for the toads to be found, and guessed that someone had just bought them and was bringing them home when they forgot to pick them up.

In an attempt to trace the owners, staff at the vets put an appeal on Facebook about the toads last week, and have kept them at the clinic since then.

On Monday, someone called in to say they were theirs, and they are expected to be collected this week.
