Besides, during this trip to Water 7, Charlotte Mousse had personally seen the Sea Train that had just been put into operation in this world!
Even if he had only satisfied his curiosity, Mousse's trip to Water 7 had not been in vain, though the Sea Train still had major limitations in his eyes.
Even with the threat of Sea Kings and the ever-changing, violent climate of this world, sea transport remained cheaper than rail, leaving speed as the Sea Train's sole advantage. In terms of positioning, it was more like the high-speed rail Mousse remembered, while its construction costs were even higher because it first required a sturdy, stable roadbed with immense buoyancy to be laid across the sea.
Although the technological expertise accumulated in this area had laid the foundation for Iceburg's grand future plan to turn all of Water 7 into a floating island, it could not be considered an efficient investment no matter how one looked at it.
Especially since the enormous expenditure was not a one-time cost. Due to the threats of Sea Kings and storms, the Sea Train's maintenance costs were far higher than those of high-speed rail on Earth.
Fish-Man Tom had come up with the ingenious idea of changing the sound produced by the train while it traveled to frighten off Sea Kings, but like the Navy's later method in the original timeline of installing Seastone beneath warships, it did not always work.
And once those terrifying storms, far beyond Earth's common sense, struck, there was no choice but to spend more money on repairs.
Furthermore, perhaps because the high sea level had submerged most coal deposits and the overwhelming majority of oil and gas resources, mineral energy in the Pirate World was nowhere near as common as it had been on
