|
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 |
