So, just got back home after dropping by to visit the exhibit. All I can say is that for a 45+ year old beat-into-the-ground-commuter car, CDTX #5008 "The Redwood" is pretty darn spiffy. There was a slight delay in getting it open to the public as Amtrak P42 #173 was being cantankerous and did not want to start initially (the consist parked on the California State Railroad Museum trackage consisted of AMTK #173, CDTX #5008, AMTK #90218,) and the Road Foreman from Caltrans that was in charge did not want to allow people aboard until HEP was turned on for lights and air-conditioning. After about 10 minutes of fussing around, the engine start bell began to ring and was followed by the chugging of a prime mover coming to life.
There were a few people waiting, but all were aboard quickly enough after the lights snapped on. The interior is spartan, but it is not exactly bad either. These are hard-working cars and will see a steady stream of people who just want to get from point A to point B, and they will be pretty comfortable I do think. The seats are AmFleet I short-distance seats with 42" pitch. They are permanently mounted though and are not capable of being fipped, so half the car has seats facing one way while the the rest face the other. Due to the decision to retain the former NJT overhead racks, the cars have a very open feel. Now I know what "New Railcar Smell" smells like too!
The list of stuff replaced is extensive, and the man who is in charge of the whole entire Caltrans Division of Rail rolling stock procurement was on hand to show off his baby. Really nice guy, and very passionate (he's responsible for the retro CalTrain paint scheme on #90218, and the "Disco Stripes" at the car ends are very intentional as a nod to NJT and the car's roots.) There are brass builders plates being made that each car will wear stamped with St. Louis Car Company, using original font and company logos, as well as the original build date for each respective car (either 1968 or 1969.) Adjacent to these will be MK plates from the 1980's rebuild as well as Amtrak Beech Grove plates for the Caltrans conversion.
All-in-all, I think these cars will be a very nice ride. Really, they were torn down and stripped completely clean and only the stainless steel car bodies are left; everything else from the running gear to the windows are new; interior-wise only the overhead luggage racks are retained from NJT. It was confirmed, one set of single-levels will be running before June is closed out (the 18th is the target date, but absolutely before 4th of July week) and Amtrak did send out several AmFleet cars in order to make this happen. The second set will be running before Thanksgiving weekend.
