The Lost Budgie Railway Halloween special

This episode was to have been the Halloween special of 2018, but the idea was scrapped because it was pretty edgy.
Plot 
Daniel was to wake everyone up early on Halloween, and a visiting engine was to tell a story from his old colliery. His story was about an early J50 who worked at a colliery, and when his brothers and sisters got replaced went mad. He murdered an 08 by pushing it into the slag heap. Then the engine left and the engines started work. Said J50 arrived unbeknownst to our protaganists. He then attempted to get rid of Daniel, but failed and plotted his revenge.
Why it never came to be 
As I said before it was too edgy and the video was never fully edited. The model was later used for Lenny with minor modifications.
