Workharder shook her head negatively at my question.
"I can give you a list of alternatives, and they are all so much worse that perhaps even to keep using the trains will be better! Oh, see for yourself, Father."
She raised her hand and began counting on her fingers.
"Mechas can't even work under this ash. Humans could, but they are so clumsy! And they are slower than trains, even the smaller ones, and aren't very reliable either. Carts pulled by beasts will get stuck in the ash as much as trains do. Boats would work, but they can only travel where rivers go. And that's it. Ah, workers can just carry items on their backs—but this is just silly! Even if we count dragons. We don't have this many dragons, and they never were tamed for carrying large loads."
I scratched my chin.
Workharder didn't mention planes, but planes had difficulty flying under the ash rain for the same reasons mechas did.
