Charles Lane is the Scrooge Homer Bedloe in this episode. He guest starred on "Bewitched" as the Scrooge Jesse Mortimer in the fourth season episode "Humbug Not to be Spoken Here".
The supercharged locomotive that is now "standard equipment" on the C&FW Railroad, as shown in their office, is a model of a Santa Fe E1A locomotive, built 1937-1938. The model is even in Santa Fe paint, with a small "C&FW Railroad" sticker over the Indian head logo used on the side of the locomotive. At 25 years of age, it's not a very new locomotive for a railroad that is supposed to be "modern and progressive".
