[Accrs] PFE R-40-27

[Tony Long]

Three of these cars still exist.  At Campo, Niles Canyon, and Portola.

I believe this was the last of the ice bunker built cars.  There is a R-40-28 which is the same general design/arrangement, except it has 8’ -0” door opening.  The CSRM has a few drawings of this. Last week I purchased the General Design and Steel Sheathing drawings.

Here is what the basic side framing starting to look like.  See Below.  The steel shapes you see so far are the Z26 82.4# Center Sill,  ZU Side Plate,  6” Channel for bottom Side Sill,  5”x3”x5/16” Angle used as the top Side Sill.  The door posts are 3 3/8” 8.3# Z 28, and the intermediate posts are pressed channel with flanges using Yoloy steel. These steel shapes are in the United States Steel catalog and provide the exact dimensions – available on Google Books.

Unfortunately,  the drawings for the individual posts (corner, intermediate, door) are not in the CSRM archives.     There are a couple other drawings I need to purchase (underframe, ice bunker detail), but I think there is enough information to create a very accurate model of this and what is missing in drawings can be substituted with measurements taken off the real thing.

Enjoy,

Tony


General View of the side framing so far.

Intermediate posts- notice how they are pressed to lap over the angle.  The steel sheathing lays on the outside edge of the side sill.

Top of intermediate posts which are connected to the ZU side plate.  There is a small offset between the side sill and side plate, therefore the intermediate post have another pressed offset. This is what they used Yoloy steel as it is good for strength and pressing into shapes.  The steel sheathing fits into this gap.

Top view of the left hand door post Z 28 and the intermediate post to the left.  The Z 28 was originally created as a side plate, but car designers came up with other creative uses.  The door opening is framed with  Z 28,  another horizontal section is used to establish  the top.
