What type of passenger trucks are these?

[peteski]

Looks like a heavyweight car but on 4-wheel trucks.  And each truck is different.  Even each journal on the 2nd truck is different.

I have never seen trucks like these (nothing like these exists on Spookshow's N scale trucks encyclopedia).  Why is each truck different? Was it something that was cobbled up just so the car could be moved?

Do you know the setting for the pictures?  Because of the two different types and paint job on the cars it may have either been a museum or preservation site or a tourist type place.  These places may have used two different truck and different journals just because that's what they had on hand or were able to acquire cheaply.  Then again, it's Rock Island car and as my friend who models RI often says they didn't care what it looked like as long as it ran.

As to the truck types - I don't know.  I wasn't able to find anything that even looked close in a Google Images search.
The journals all look like roller bearing types, just different models.

John,
those photos were taken recently in the back lot of the New York State Exposition grounds. It is a sort of a museum of several pieces of rolling stock.

Chris, so you are saying that these are powered trucks?  That would explain why they look so different from standard passenger trucks. The photos of the Con-Cor model are rather small and the trucks in those photos aren't clearly visible.  I'll have to take your word for it.

According to the link the one with the roller bearings is powered. On the Concor link they are shown with pick-up shoes so look a tiny bit different.

These were interesting cars to model since the PRR / Long Island actually used 2 Different Trucks under each car. The powered Truck was an 8''-6" Roller Bearing Truck (Left) ,
and the non-powered an 8'-0" friction bearing truck.

I'm sure a bunch of PRR people will tell you all about them 

2CP2 or Hyatt roller bearing trucks?

That makes sense then.  They would probably have had access to scrapped MP54's and used the trucks.

Scroll down about 1/3 of that page Chris posted and you will see better pictures.  They look pretty close, although not exact.  But that could be years of maintenance and patching.  And maybe the result of removing traction motors.  Although the second truck picture Peteski posted looks like there might still be motors in there.  Odd, but I couldn't find any close up pictures of the real trucks online.  They're probably there somewhere, just hiding.

From the Con-Cor link:

"These prototype cars had one powered truck on one end and a non-powered on other end, these trucks had different wheel bases. ( 8'-6" for powered truck and 8'-0" for non-powered truck. It was a bit tricky to design a model with two different wheel base power trucks, but they run just great. It was also unusual that the "prototype powered truck" on many of these cars was the PRR 2D-8-P1 Hyatt Roller Bearing Truck, and the "prototypenon-powered" was the 2C-P2 Plain Journal Truck. (We double checked all references with our friends at the PRR Historical Society, as it seemed odd that the PRR would mix Roller Bearing and plain bearing trucks on the same car... but turns out, that is correct.) And you can get a bit crazy going through all the PRR classes and sub-classes on these cars, which ran to almost 40 pages of print out, in a type face that is smaller than you are reading here."

On the Long Island RailRoad these were 3rd rail powered individual units.

Thanks everybody!  I had no idea where this would take me (into the Pennsy country).   

 Thanks for the direct links to those truck pictures Chris.  I think last night the Con-Cor page you pointed me to didn't fully load in my browser because I didn't see all those detail photos.  I did now.  Those model trucks sure look like the real ones I photographed.

If you need them, I think the old Bachmann "shorty" P54 cars have them (without the 3rd rail stuff, of course):

  Walthers had HO versions of at least the Powered truck for years.
  they also has MP54 kits with Metal sides for years.
  Walthers may have also had O kits at one time ?
  but never in N scale.
