Just had to register to add my two cents.
A couple of years ago, fresh with my "success" in building an approximation of the Three Rivers
as it ran under Amtrak, I had the mad inspiration to create an approximation of the Amtrak Auto-Train...
...Oh yeah, I'm an O Gauger. Hence the "madness".
I had been collecting the MTH Auto-Train autoracks (they modeled the ex-CN bilevels) for the better part of a decade when I made a snap decision to gather everything else needed--Superliners and appropriately decorated Genesis diesels. I succeeded in acquiring an example of every five-stripe Superliner put out by MTH (13 cars) and tracked down one of each number of Phase IV-striped autoracks (albeit with a few Phase III versions mixed in) for a total of 15.
All that was left were the Genesis units. I had four--a power/dummy combo by MTH and another by Williams. Only problem was these were Phase III. The only "wave scheme" units made in O Gauge (until WBB's version that just appeared in their catalog) were a special limited run done for Walthers by MTH after the former's mad scheme to build their own O Scale version went nowhere. These units are difficult to find and command a king's ransom when they appear on the secondary market. So I did the next best thing-- sent mine to a custom painter.
New numbers were picked for the MTH units. One of them had a missing front number board (#824) which I replaced with another unit's number board (MTH only had boards for #825 in their spare parts inventory). While packing the units for shipment to the painter, I found the missing #824 board in the box, and elected to turn the other unit (#64) into number 825. How the Williams units were renumbered I don't recall, but they went from #805 to #827, and #810 to #819...
A year later, after posting the photos of the newly-arrived units on the O Gauge Railroading
forums, someone pointed out that #819 was one of the units destroyed in the Sunset Limited
wreck of 1993
