As you weren't specific as to exactly where I was during this scenario let's assume that I was standing next to that pile of guitars.
Within 5 seconds they would all be moved to safety off of that track. Within 5 minutes they would be even more safer in the back compartment of my Pleasure Way. It would be my civic duty to save those guitars.
Oh, and as that train went sailing down that first track I'd walk over to the second track and boost that guitar as well.
Remember... it's my civic duty.
