截止到2006年12月3日18时30分,21组时速200km新型提速道岔在哈尔滨铁路局长滨线五家站和兰陵站铺设成功。这是继青藏铁路冻土施工成功后,铁路更新改造施工的又一成功范例。在如此高寒条件下,更换大型提速道岔施工,在铁路更新改造中尚属首次,此举为2007年铁路实施第六次大提速奠定了基础。 As of December 30, 2006, at 18:30, 21 sets of new speed-increasing turnouts with a speed of 200km per hour were laid successfully at the Wuhu Railway Station and Lanling Station on the Harbin Railway Bureau. This is another successful example of the construction of railway reconstruction after the successful construction of permafrost on the Qinghai-Tibet Railway. In such alpine conditions, the replacement of large-scale speed-up turnout construction is the first time in the railway renovation and renovation, a move that laid the foundation for the implementation of the sixth major speed-up in 2007.
