Sudrian Railway Ghosts

I have come up with some ideas on the Thomas series orginated by and on YouTube, Sudrian Railway Ghosts.

The Organist of Sodor Castle:

In the early morning of Christmas Eve, Sir Handel hears mysterious music coming from the abandoned Sodor Castle. There’s no one to be found, but the ancient pipe organ keeps on playing day after day. Duncan laughs this off as a joke… until he takes the late night train.
Based on the villain Forte from Beauty and the Beast: The Enchanted Christmas:

Terror in the Clay Works:

Bill and Ben are hounded by the ghost of a kind, loving, and generous scientist, whose accident resulted in his becoming a homicidal maniac. In the China Clay Works is the spot where he slew pursuing policemen and fell to his death. Can nothing save the twins from this 19^th century nightmare?
Based on Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde:

Gordon and the Headless Driver:

On a night run with the Express, Gordon has a ghostly encounter with another Express engine and its driver, both of whom had perished during a German air raid in World War I. Neither can rest until the driver’s missing skull is found and restored to him.
Based on Washington Irving’s The Legend of Sleepy Hollow and the 1999 movie adaptation of the same name by Tim Burton:

Alfred’s Revenge:
A specter from Thomas’ past returns to vindicate himself on all the little tank engine holds dear. When Rosie goes missing, Thomas’ innermost fears are realized. Now he must rescue the engine he loves from the ghost who had been both his harshest mentor, Edward’s closest friend, and a war hero.
Note: The flashbacks will serve as a “midquel” to The Adventure Begins.

I'd like to write them, but I don't know how each story should be executed. Fortunately, I know a few guys who might be able to help:
