There are 2 rail dual beam bridge, for pad beam pad on each node truss should get off track, on the edge of the I-beam to pad.
双梁桥架上有2根轨道，用于桁梁应垫梁应垫在各节点处，下车轨道边上的工字钢也要垫好。

Intermediate driving way is put forward for the first time and can solve influence of deflection and edge effect come from rail beam on mechanical and electric performance.
首次提出中间驱动方式，能较好地解决轨道梁产生的挠度、边缘效应等对机械和电气性能的影响。
