Form Herb:

Were the air cars so poorly maintained or so deteriorated mechanically that 
you made it a point to change out for a 1700 whenever you had the "over the 
hill" run?

For anybody who recalls the 1727 runaway accident:

What caused the brakes to fail on 1727 when it ran away and derailed? That 
made the paper way out here in Las Vegas.

No broken air lines on that car... ;-)
