The only downside to the Thunder Beasts pulling carts was the slow speed, which couldn't compare to the swiftness and convenience of horse-drawn carriages.
Essentially, horse-drawn carriages could pass three to four Cold Spring Points in a day, while the Thunder Beast-drawn carts could only manage two from dawn to dusk.
A journey along the Mountain River Trade Route that would take horse-drawn carriages only three to four days would take five to six days with Thunder Beast-drawn carts.
With the extended time, the variables increased as well.
Therefore, Thunder Beast-drawn carts only operated on the trade route for a brief period around the peak of the hot season; during the ice period and its adjacent times, Thunder Beasts seldom ran on the trade route, being used only within the territory for transporting goods.
But even just a few trips of the Thunder Beast-drawn carts could transport an amount of goods that rivaled the annual haul of horse-drawn carriages.
