[Request] Hanging walkway.

Im looking for a walkway, similar to the one in the shown below, but in a more TF2 style. In addition to that, I would like a separate prop that could be added on to the end of the walkway, to make it look like the end has collapsed.



If anyone can do this, I would be very grateful.

Also: Please ignore the mind-numbingly bad quality of the pic, it's a screenshot from a video off of YouTube, since I don't actually own Portal.

EDIT: On second thought, I really only need the end of the walkway, since there are railings provided and it only takes one brush to make a normal walkway.

Right. What about the railings though? Im using the spytech railings, and while I could try to recreate them using brushes, I have a feeling that it will turn out very sloppy. I don't suppose there are any other railings that have a collapsed version that I might have skipped over?
