Another thing of note, is just how dull this route is to drive without scenery.

To traverse the roughly 135 miles, it will take you:
Passenger Train @ 79mph: ~2 Hours
Freight Trains @ 50 mph: ~2 Hours 40 Minutes
Passenger trains are tougher because of game oddities with how the physics works making a prototypical Broadway Limited with three E8s on the lead maxes out around 65mph. So another engine will be needed for the Broadway.
A default HSC consist of something like twenty-six boxcars, one caboose, and two DR-6-4-2000s had no issues reaching 50mph and it mostly sat in notch 2 much of the way and just hummed along.

At this time, there are only a small handful of things to do before I start making towns and countrysides look like they should. All that remains is to properly set speed limits at turnouts and yards. Then adjust a few more grade transitions where they are not quite to my liking.
Everything else is finished save for a few pieces of track in Fort Wayne on an adjacent railroad, but I need to find how that small yard and turntable was set up.

TL;DR
It's a long, straight, and dull route, and hopefully scenery makes it a little less boring to run. They didn't nickname it the Fort Wayne Racetrack for nothing.
If I keep at it the way I have been, expect some early scenery pictures in next week's update.
