The best explanation I have heard is that the separate line for the
ECV's and wheelchairs isn't working reliably and is frequently shut down. I don't know the full reason, but they are having to stop the gondolas to load ECV's and wheelchairs a lot more than planned. The Riviera station wasn't built with that separate detachment space for the ECV's/wheelchairs, so they are having to stop the line every time someone gets on there. I have thoughts on this decision to put these detachment areas in everywhere but there, but that is for another day.
