央视网消息：记者从国铁集团获悉，今年一季度，铁路建设优质高效推进，全国铁路完成固定资产投资1379亿元，同比增长5.1%，实现全年良好开局。
今年以来，国铁集团聚焦服务国家重大战略和区域经济社会发展，充分发挥铁路建设产业链长、辐射面广、投资带动强的优势，加快推进铁路建设，一批重点工程项目取得积极进展。
一季度，西安至十堰高铁、雄安至商丘高铁山东段启动联调联试，开通运营进入倒计时。成渝中线高铁桥梁全部合龙，沪渝蓉沿江高铁安徽段隧道全部贯通，重庆至昆明高铁云南段顺利推进，成都至达州至万州高铁嘉陵江特大桥、合肥至池州城际铁路池州长江公铁大桥、沪渝蓉沿江高铁沪宁段崇太长江隧道等一批重点控制性工程建设取得阶段性成果。
下一步，国铁集团将积极推进“十五五”规划确定的各项铁路重点工程建设任务，全面落实今年重点项目。国铁集团发改部项目处副处长郭春江表示，国铁集团将加强战略骨干通道建设，减少西部重点地区铁路“留白”，补齐普速短板，发展城市群都市圈轨道交通，打造一体衔接的现代化枢纽体系。
