Is this people mover in service?

The operation was definitively terminated on 27/08/2016.

Oh, what happened then?

The classical story.
The construction was financed by the French state. The costs of operation were budgeted by the city and were not too expensive, because it was a fully automatic vehicle.
Unfortunately, the city was unable to cover the costs of the much-needed renovation of the entire installation. The demolition of the whole turned out to be cheaper than the renovation...
