South West Trains is reuniting a girl with her homework after she left it on one of their trains. 

Robert Hallam tweeted South West Trains to say his daughter had left her homework in a Scrabble box on the 7.27am service from Ashford, Surrey to London Waterloo.

The train firm lept into action, and it was not long before a manager found the box on the carriage. 

Not only was it kept safe, but South West Trains then began to work out how to reunite the owner with the homework.

We hope she gets top marks!
