Superliners. Ahh, yes! Lots of ideas here. First of all I believe Superliners are among the very best railroad passenger cars ever built. My reason for saying this is that I have seen quite a few wrecked passenger cars in person and in photos. In the case of older, lighter cars, the damage is invariably greater and, most importantly, the damage to the passenger-carrying portion of the car is much greater. The end/corner construction seems to be the weak point of most passenger cars, but these areas are incredibly strong on a Superliner. During my Amtrak career, I always said that if I'm ever in a wreck, I want to be in a Superliner. I was lucky. It never happened.
The Superliner II's, in which I worked, were built around 1994-95, if memory serves me right. That means they were 20 years old when I retired. Twenty two years now. And the Superliner I's are much older. As many folks have suggested, old equipment can be very serviceable, but it has to be constantly maintained. This is true whether it's an 1880's Jackson & Sharpe wooden coach, a WWII Corsair, a Berkshire steam locomotive, a Model T, a B-52, or a Superliner. As a number of people have said, it's largely a matter of money.
But it's more than that. Over the years, I got a reputation as a pain in the ---- uhhhh ---- neck for reporting defects to the Sanford Mechanical staff. They often disliked it when I reported something minor, but many of them begrudgingly realized that I just wanted my car to be as good as they could make it. They thought I complained too much, but I don't know how many of them realized that I was actually expressing confidence that they COULD do a great job. Considering all the b****ing I did over the years, they might be surprised to know that I strongly believe the Auto Train Mechanical Dept. at Sanford and Lorton are the best Amtrak has.
Early in my Amtrak career, I worked on the extra board on just about every train out of WAS. Sunnyside (NY) had a particularly bad reputation. You could report a defect on a car arriving Sunnyside. Then the next time you saw that car you would see that the repair had never been made. So you would look on the Mechanical record (Amtrak Form MAP-21A) and see a note "Repaired --- Gomez". I eventually learned that there was nobody at Sunnyside named Gomez. Of course these were not Superliners, but the point is the competence of the workers and the people who supervise them. I saw similar evidence of poor performance at Chicago. I am sure there are good folks working at those locations, but the best of them can't always overcome the deficiencies of the worst.
Overall, I am convinced the Sanford and Lorton Mechanical Departments were the very best during my years with the Company. Lorton has fewer resources and a smaller maintenance facility, but those guys could work wonders with that aging equipment. By the way, I understand the Auto Train folks did most or all of the LED installations on the Auto Train equipment --- not Beech Grove.
One serious problem faced by the Sanford and Lorton staff was always a lack of parts. Sometimes (I have been told) they couldn't get parts from the supplier because the supplier refused to ship until they were paid for previous bills, often dating back a long time. Can you blame the Mechanic for the paper-pusher's failings? Sometimes the replacement part wasn't available because it hadn't been in production for a long time. That's what happens when you are operating 20 year old equipment. This was further complicated by official policies that prohibited the removal of components from an out of service car for use on another car.
I know that this has been a rambling account, and I apologize for that. Until the Superliners are refurbished or replaced, remember that socks do work to stifle rattling doors, but towels are bigger and better, and can be obtained from your SCA for the asking. Towels are also great for blocking that excessive air flow from the overhead vent.
Be safe & enjoy the ride, everybody!
