Identify the character

Are Sir Topham Hatt and the Fat Controller the same person? In the television series, Sir Topham Hatt is the railway manager also known as the Fat Controller.

Why is Emily sometimes shown without number 12? Emily appeared without a number for much of the original television series. She receives number 12 in the story Emily to the Rescue in series 24.
