(erielack) Need names of parts

[Dennis Sandow <dsandow_@_garden.net>]

On 10 November, Gladstone train 717 had a grade-crossing incident.  The damage to the MU consisted of some scrapes. See http://www.longhillnj.org/lht/picts/carvrr_2.jpg (Damage to the auto was much worse.)

The question is this: What are the exact names of the parts that were scuffed up?  By deduction, I can figure out the function of the parts, but I'd like the proper names for use in captioning the photo.

Thanks
