Yeah, I guess I should explain my thinking:
They need up close access to the track this is normally because of inspection or replacment of parts, from what I have seen they are putting it up quick, but it dosnt look like it will be done for a few hours then they have to preform the work, which if it is a quick inspection would be a few hours, then dismantle it again.
i could see the work being done for tomorrow if they dismantle it through the night and the work to be done is only a few hours, but if they are replacing a part or doing a close inspection they will probably want to do some testing which would probably take quite a while so at best it won't be open for a little while (a couple days including today)
