The guide stood in front of the crowd, maintaining order while presenting his product, "This is the most advanced steam train in the world, capable of reaching a terrifying speed of 90 kilometers per hour!"

"The key is the power it can provide, which is more abundant than all previous train engines, allowing it to pull 20 carriages!" he explained as he walked from the front of the train to its tail end.

Then, he continued, pointing at the train tracks below, "Standard gauge, no modifications needed to use this type of engine head! It's revolutionary! Perfect!"

"There's no stock available... sir... this is for exhibition purposes... to demonstrate the Great Tang Group's leading industrial technology... If you want in-stock items, you can place a pre-order," the guide politely responded.
