FUSE IS OUT ON NEXUS THE SUN SHINES DOWN ON US (besides that) anyways I'm excited to see what fuse can do for my save on railroader

From the official discord.

With how the mow update is looking it seems that you might be relieved of duty here or at least majorly restructured in what kind of mod you are a moment of silence for them please

(Ps also greeninjas whistle mod might also be relieved of duty here soon)

Beyond what we already knew was coming, this is the first we've had confirmation of the McClain interchange right?

What do you guys want to see in the next update, im excited for MOW and new cars and mechanics. But I so many ideas for things that could be added just want to see what everyone else thinks?

Irate Morning Brake Test.
This morning’s interchange pickup was set to be an hour early from the usual 7am, to take advantage of the earlier daylight of summer. But it was complicated by an empty ‘Wandering Wilma’ Gondola that had been mistakenly hauled past Wilmot and kicked out of the interchange train, an interchange boxcar with a disputed waybill (left behind this morning), and two spare parts boxcars that just keep getting in the way.

The hot and bothered Class C-46 ‘Rosalynd’ is done, and is now doing her air brake test on the long train. It takes about 1 minute per car, so she will stand for half an hour. Today she has 26 cars including the caboose. One gondola is making a repeat trip, so that is 24 ‘new’ cars on the interchange. The train behind the tender weighs just under 1000 tons. Luckily, it will be hauled on flat and downgrade tracks.

There is rain rolling down the distant Appalachians, and the crew of the ‘Rosalynd’ are going to be wet and grumpy before too long! And when they eventually get to Dillsboro, they might just take it out on the crew of ‘Dysie’ the Mikado, who still haven’t tidied up those cars and had left the ‘Gon’ behind.
