The history of the locomotive

 

Locomotive: In 1905, the Trans Siberian Railway was fully opened, and the trade route between China and Russia completely shifted from the Jin Mongolian region to the northeast. Russian merchants switched to railway transportation via Vladivostok, which was not only low-cost but also extremely convenient. The entire transportation time was only about one-fifth of the original land transportation time for horses and camels. This modification took a step forward in the development of productivity. To commemorate this meaningful event, the "locomotive" trademark design was derived from it.
