Granted the Arrow II's had their teething pains, but once past that they were very good. The Arrow III's were much better, they had the benefit of improving the short comings of the A-II's. Don't forget the A-II's were run hard, they were replacing a very aged MP-54 Fleet. Now the piece of junk you should be referring to were the A-1's. The were junk from day one, as a matter of fact a couple of them burned from defective on-board battery systems while in storage. They never ran well, broke down, doors that open on their own at speed, all types of good things. The A-II's were light years better than the A-1's. I rode them all over the years, MP-54's, A-I's, A-II's, and A-III's. I understand the A-II's were never rebuilt because it would have been to expensive to bring them up to A-III standards. Another interesting fact, the A-III's were seeing limited service for years because the Morris & Essex hadn't been coverted from DC to AC yet. By alternating units, they prevented any units from running up excess miles before the M&E line was available to them.
