Back in 1999 I took the train from Carcassone to Paris. I was surprised to see a steam locomotive, seemingly ready for service - certainly it was spotted in the midst of a very active junction. Can anyone identify this locomotive for me? From what I remember, this is on the eastern side of the main line from Toulouse to Paris. From the image data, this location is about an hour and a half north of Carcassone - we took the express train that didn't stop more than once or twice before this location, so I'd guess that this is about 150-175 miles north of Carcassone. It's also about an hour south of Cahors, judging by the data in the frame after this one.
In many European countries there are occasional Steam Specials. You don't give enough information and it is too long ago. The magazine Todays Railways might know.
Was the location Toulouse? From there it could have been going to Lourdes or Pau on the southwestern line. Or else back to Carcasonne. There are a number of other destinations possible. I suspect Bordeaux would be too far.
