Noticing that there was an inspection pit beneath the locomotive, Mr Monkey scampered underneath the Caerphilly Castle. Built in August 1923, and used until 1960, this was the first of 171 Castle class locomotives. Mr Monkey suspected someone had tidied up the underside of the locomotive, because nothing dripped on him as he scurried beneath 126 tons of machinery.
