Yes, I agree, but AFAICT we have two questions in this subthread:

- about common usage of the word - and here it _seems to me_ it's context- and domain-specific, because for instance we don't call cars a road infrastructure

- whether Polish penal code treats trains as rail infrastructure - and here I don't know, but I found a railway transport bill that lists what's considered infrastructure, and trains are not there

In NL I know for a fact the locs wouldn't be infrastructure, the term used is 'rolling stock' and they are usually owned by different companies from the infra.
