refueling stations/filling stations


Explanation:
Hello,

That's how I read it.

alimentation = filling stations/refueling

I hope this helps.

disagree  ACOZ: Not appropriate for electricity, though, Matthew.
2 hrs
  -> You're right. Thank you.
disagree  Tony M: The reference to 25 kV makes it pretty clear this is an electrical context, so this wouldn't be applicable. / Maybe in that case a confidence level of 1 "I'm only guessing" would've been more appropriate?
3 hrs
  -> Thanks, but ACOZ made that quite clear. I'm no expert...just trying to help... What's your point? Don't you make mistakes? I've often had confidance levels of 1 when I post, but I knew the idea here, so I went for three. "3" isn't that high, is it? LOL.

power supply points


Explanation:
With 25 KV, it has to be a power supply.

disagree  Tony M: Maybe, but not in this particular context; 'power supply point' doesn't sound like usual technical jargon to me in this context; I think these 'postes' are in fact thumping great substations!

agree  Michel F. Morin: Yes, sure for "power supply". Now, I'd suggest "station" instead of "point".

25 kV poste d’alimentation
25 kV (supply) substation


Explanation:
Usually a 'poste de transformation', but I think it's a fairly safe bet (though wider context might confirm) that these are in fact substations providing a mains electrical supply, almost certainly being transformed down from an incoming 25 kV line to some more manageable voltage.

Although my general explanaion is correct, Bourth's answer is in fact the one you need here, in this specific context of electrified rail networks.

neutral  Michael J.H. Davies: I agree with your added comment, Tony. By the way, 25kV is quite normal for railway electric locomotives; supplying the power at this voltage means that the current (kiloAmperes) does not have to be so high, thus keeping line losses at a lower level.

  -> Thanks, Michael! Yes, indeed, I had initially missed the point that this was for the actual tractive power; I'm more used to the 3rd rail low V / high I system in my region of the UK
