Anyways onto the 2/27/21 Update
Fergus:
Fergus' main chassis was basically completed, quite a bit of cut-away plastic was used to help fill in some of the gaps. Additionally, a bit of it was used to fit the front wheel into place correctly so it would be level with his drive wheel.
Front of Fergus:

Rear of Fergus:
A bit of plastic had to be shaved from what was left of the runningboard to allow for clearance on the rear bufferbeam.

Top of Fergus:

Bottom of Fergus:
A proper way to hold the two pieces in together aswell as that front wheel still needs to be worked out, it'll probably be a long screw that goes through once everything is fitted in correctly.

I also would've worked on the Locomotive Driven Emily today, however I'm gonna push her off for another week or two due to other pressing matters at hand right now.
