That's right. I plan on releasing the Island of Sodor this weekend.
If anyone would like to make TTTE trains for Locomotion, now is the time.
EDIT: Did I say this weekend?

RELEASE: After months of saying I'll work on it, it's finally done!
Name: The Island of Sodor
Goal: Deliver 100,000 tons of coal/slate (a few of the coal mines I called slate mines)
Difficulty level: Challenging (Tough to get it started)
Competitors: None

This map includes the whole island, the Isle of Man, and part of England. You may recognize a few landmarks, such as Brendam docks, Gordon's hill, Henry's forest, and so on.
But that's not all:
The download includes the official Island of Sodor Guide, which includes a locomotive naming guide, explains my theories on the "special" industries (such as the fish market), and many other tid-bits.
Please enjoy!
P.S. I'd like to dedicate this to the Rev. Audry. Without him, none of this would be possibe!
EDIT 3: I've fixed the scenario so that the earth slopes and Class 42 are no longer required.
EDIT 4 (11/8/06): V1.2 Released. I removed the station mod.
EDIT 5 (11/9/06): V1.3 Released. I removed the extra content from Trensim.com.
EDIT 6 (11/9/06): V1.4 Released. I had a report that a sound file (which hadn't been selected in the scenario) snuck into the download, so I removed it.
EDIT 7 (12/23/06): I've given up on trying to remove that sound file. It is part of the Class 42 "Warship" by Pikkabird available here, his 1927 Express Passenger Carriage here, and Steve's Earthslopes here.
EDIT 8 (8/20/07): I've restarted work on a brand new Island of Sodor V2.0. This new version will require no extra files, improve the old version, and include textures to show where tracks should be built. This will take a month or two.
EDIT 9 (11/29/09): I haven't done much work (barely any, really) on V2.0. I don't play LoMo these days, so V2 may never come out. I apologize for the disappointment, but I'm much busier than I was when I began the project.
Also, check out the Thomas the Tank Engine Pack V1.2 here.
