The squirrels boarded "without tickets, breaching railway byeclaws", a spokesperson for the train operator joked.
The squirrels jumped on the Great Western Railway (GWR) 8.54am train from Reading to Gatwick on Monday, forcing passengers to flee to other carriages.
The passengers alerted staff, who tried to lure the squirrels off the train at Redhill with snacks, before trying to force them off with brooms - but to no avail.
They subsequently called the journey off entirely.
Illegal? I mean in the US yeah, we’re supposed to vaccinate our pets and such but there are still wild animals that could be rabid.
We have coyotes, raccoons, and opossums where we live, and they aren’t anyone’s pets. So you try to stay away from them and keep your pets away, too, if they go outside as a precaution.
We had a dog once that ran outside unexpectedly when we opened the door because we heard something. It was an opossum and he attacked it. He was vaccinated and okay, but we grabbed him and drug him inside and made sure that neither one of us had cuts or anything…he was covered in blood and enjoyed a nice long bath after.
