Damaged "H" channel removed from the first festooning car, and spare channel was put in place.

Note: it seems like the aluminum channel is not strong enough for the forces its being put under, and is resulting in deformations (See picture "Festooning car H channel deformation"). We suspect this has happened in the past, notches were cut out where the deformation likely occurred and then the part was flipped and put back in place. There was two notches on the bottom face of the part we took out, and there was already one on the spare part. (see picture "Festooning car H channel bottom face"). A new channel needs to be designed out of steel for the first car to prevent this from reoccurring.
