This loco is basically an updated 2017 version of the Railbricks Fairbanks Morse H10-44 engine that was built by Jeramy Spurgeon back in 2007 for the Hobby train set number 10183. (It didn't make it into the final set but was considered for it) I was also inspired by this topic here on Eurobricks by user dx0. I wanted to make it in orange like his model, but decided on yellow after looking at the Technic 1 x 4 brick, which doesn't come in that color.
The elongated model features a new slope brick that actually very closely mirrors the real loco, along with space for railways initial tiles and printed numbers. I am going to name this loco WFP number 7004. (WFP stands for Wabash Frisco & Pacific, which is the name of a 12 inch gauge ride-on railway in St. Louis, MO. They really have a Fairbanks Morse-like loco there numbered 704, so this engine is partially inspired by that!)
The rear of the loco features the cab door and the tail-light.
The LDD file is available here if anyone wants it. (UPDATE: I revised the underside of the engine to be beefier, along with a bunch of other small modifications. The LDD file and pictures are updated as of 1/24/17.
