The number isn’t misleading if we’re talking about efficient movement of goods.

I’m unclear why you’d care about value at all in the context of this discussion. In context weight and volume are the most relevant metrics.

Why would one want to emphasize value over weight? If I load up a train with extremely expensive metals, jewels, artwork, etc. couldn’t I raise a countries rail by value measurement overnight?

I agree it's good to consider the whole picture, but ton-miles are probably the most important to consider given the increased diesel required to truck heavy loads, correct?

Plus congestion and labour etc.

And how does that compare to Europe?
