Wang Tao followed Duan Xuchang into the vehicle and noticed it had undergone significant changes compared to before.
Previously, the Debris-clearing Train was equipped with many high-tech devices; now, not a single one could be seen.

Probably the only difference is that steam engines burn coal, while Debris-clearing Trains burn Crystal Cores.
"Looks pretty good... But how do you guys solve the communication issue?"
Wang Tao was curious.
