E.D.W.M.W. Stands for: Earth, Digital World, and Magical World. the Locos you see are fictional, so let's get started:

#13 1/2: "Toots" the 2-2-0 Made in 1945, this engine goes around from a giant coal mine and delivers it to the Magic Crafters town of Wizard Peak. Toots did this for 60 years.

# 1 1/4: "Tootle" the 4-4-2 Built in 1932 this branch line engine goes around parts of Avalar, Dragon realms and the forgotten World as a passenger engine, going to some real neat places. (Inspired by the book Tootle)

# x3.2: "Ringo" built in 1967, saw the 60's world fair and was used around the magical underworld of New York and the city of Trollsanopolis for a pretty long time, before it was replaced by newer models.

#79: "Jasper" Made in '83, this Tank engine was different, it was originally a giant apple but the local locomotive works was running out of supplies and quickly stuffed the boiler, dynamo, cab, water injector, Etc, into it and then gave if to the railway, at first the railways was gonna sue but Jasper proved itself that it could run just as well as any old switcher could.
