I have the mod, I see in map view I can place micro wagon ghosts, but I don't see where in the tech tree they are unlocked or how to build them, Is there some part I'm missing?

They are unlocked by 2 technologies. "Micro wagons" and "Micro tanks", which are unlocked after railway and fluid wagons respectively.

Please tell me if the technologies appear, as it might be a bug or mod conflict.

Sorry I don't see the technology - I even turned off all my mods and I don't see the Microwagon technology after the railway tech

Got it. Let me see what I can do.

Did you update to 1.0.1 already?
0.9.0 wasn't complete and didn't have tech/recipes.

Oh i finally got it working, got distracted and didn't touch factorio for a while. I'll give you proper feed back in a couple days. thanks for the fix!!

No problem!! Thanks a lot :D
