蹄儿出轨断轴的原因找到了，横向超重！

贾和平 说:
Sure Alstom tried to imply that. I want to see what RTG, particularly SNC- Lavalin says.

Once found "There [are] flat spots appearing on the wheels, so they're not perfectly round,” ( Note; Doesn't it sound funny?) Councillor Allan Hubley told The Rob Snow Show on 1310 NEWS. “[Rideau Transit Group] has to run these trains through what's called a lathe, that rounds out the wheels again.”

That could cause a circumferential issue on bearings.

Ah! Advanced and tech lead countries.

太逗了，轮子不圆也来了。
虽然我同意阿尔斯通要推责任，但是我觉得以阿尔斯通这样的老把式，轮子不圆太搞笑了吧。
如果RTG找来找去就这么个理由，那问题大概率是他们自己的。
 
首先半径小，第二轨窄了，转弯时斜度更大，轴受的倾侧力更大，（相对宽轨，标准轨）阿尔司通应该明白。轻轨列车要求更高才是。所以没那么容易处理
