俄罗斯（原苏联）是世界上发展重载铁路较早的国家之一。在发展７５ｋｇ／ｍ轨道结构配套技术和铺设超长轨节无缝线路等领域，从理论和实践方面进行过长期的科研探索，积累了丰富的经验教训，可供我们借鉴。本文摘自“７５ｋｇ／ｍ钢轨重载轨道结构科技考察团赴俄考察报告”。
Russia (former Soviet Union) is one of the earliest countries in the world to develop heavy haul railways. In the field of developing 75kg / m track structure supporting technology and laying ultra-long track section seamless track, we have conducted long-term scientific research in theory and practice and accumulated rich experience and lessons for our reference. This article is from “75kg / m rail heavy track structure technology research mission to Russia inspection report.”
