Thanks for the info! I thought it was a control tower for the old railway line. Since there was only one track, this tower was used to ensure that two trains in opposite directions did not use it.

Saint-Rémy-lès-Chevreuse is the small town that you see displayed everywhere in Paris, because it is the RER B Terminus (South track). But it could have been otherwise! You can even walk along the old Limours (or Sceaux) track. For some obscure reason, the track stops there, but the old track continues!
