Why won't my game allow me to send aerogel on IT's? Message says: Oops! It is not suitable for the train and it is a Hyperloop. What am I doing wrong?

How much do you have?
Materials sent with international trains, come from your own stock
So being unable to send out certain cargo wagons, usually means you don't have the materials
My bad. Didn't realize I wiped out my supply. Thanks!
