What was Sir Handel's original name in "The Railway Series" and it's animated counterpart "Thomas and Friends?"

In the original Railway Series books by the Rev. W. Awdry, Sir Handel (a narrow-gauge steam engine) had the original name "Falcon." However, when the stories were adapted into the animated television series "Thomas & Friends," the character's name was changed to "Sir Handel." This renaming often occurs during the transition from original source material to adaptations, and it's not uncommon for characters in book series to undergo changes in name or other details when brought to television or film. In the case of Sir Handel, the name "Falcon" was used in the books, but the television series opted for the name "Sir Handel."
