This wooden train, only over half a meter high, at least in appearance, was not much different from the old steam locomotive Joseph remembered.
Except it had a pair of massive front wheels for driving—Trevisick couldn't design a combined suspension system, and Joseph wasn't clear on the principle. So he used oversized driving wheels instead.
Trevisick pushed the model's piston rod by hand, and the wheels immediately began to rotate smoothly.
He excitedly rambled: "Your Highness, I calculated precisely last night, if a 90-horsepower steam engine is used to drive it, and it carries 9 coal cars and 16 carriages, the speed can reach 38 kilometers per hour, continuing for 800 kilometers with one coal refill."
According to the Crown Prince's suggestion, he found it necessary to modify the LJ98 type steam engine and reduce its size, which resulted in the power reducing to 90 horsepower. However, due to the significant improvement in the train's overall design, this power was sufficient.
