So, working on this big ole update, don't have screenshots yet, but here's some features
Nwedaga-Deux gets an expansion, which includes:
-A new trainline, that takes you east, towards Nchuleft
-The traincar interiors are now explorable, as is the boiler of the engine.
-Also, there's a conductor's hat
-Some previously unenterable doors are made enterable, leading to...
-A dwemer submarine-boat thing, which is capable of taking the player to more Dwemer ruins
-More NPCs and features, healers and merchants and that sort of thing, as well as some ghostly citizens, to make you feel like you're ruling a Dwemer city, and totally not an idiot in some abandoned cavern screwing around on trains.
For Omicron City, there's a bunch of new interiors, since people keep complaining about that, which in addition to normal houses and such include:
-A subway/locomotive works
-Waste disposal area
-A radiostation (Which totally doesn't work, this isn't Fallout after all)
-Guard Headquarters
-More factories
-Some more offices for bureacrats
-And a player home
