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.
Rabies is virtually eradicated in the UK. Bats and imported animals are a potential risk, but the chance of a squirrel having rabies is nearly zero.
I honestly didn’t know this. Thank you!
