As this "accident" happened at Nowergup depot there is little that the PTA can do about it, as the mainenance and repair ot the "B" trainsets are the responsibilities of EDI- Bombardier who have control of the Nowergup facility, so any arrangement to have the trainsets involved repaired rests with EDI-Bombardier.
Any employee of that company would be endangering their employment if they were rash enough to make any photograph of the damaged railcars for their own use prior to any inquiry as to the cause of the "accident".
Incorrect, the PTA encorporate this mate. The repair of this train is NOT the responsibility of EDIB (EDI are not an insurance company) however the Maintainance is. I acqknowledge that EDIB are in contract to MAINTAIN these trains, but damage due to accident is not necessarily covered. The PTA can choose what to do, but will most likely work with EDIB and come to a resolution that is the quickest, safest and cheapest.
Depending on how serious the damage is, you could see two sets being sent back, if its fixable here, well, thats what will happen.
Photograph of the trains would be good, however employees and public must follow with rules and laws, and if photography is 'illigal' then dont do it.
