Re: PRR F34 flat

Hello Bruce
                     Thank you so much for the photo of the brass car. Now we're getting some where. I was a bit confused at first about the placement of the brake equipment. I have never seen a car equipped with a duel brake arrangement. What I was really confused with was the arrangement of the brake lever assembly. From what I have found in my instructions F&C doesn't really explain their installation. The photo of the brass car you so graciously, provided however does clearly show the arrangement of the brake levers on the span bolsters. This really helps me with understanding their installation. Now I can move forward. A BIG thanks again. I would also like to thank all the rest of the group for their help as well.

Good Day to all
Dave

Dave,

Looking at the very same resources that you say are not helpful, here's what I have figured out...

1) Brake cylinder - one brake cylinder is mounted to each span bolster so that when looking at the car side-on, the cylinder shows on the left span bolster. If you look at the photo of 470202 from the Hagley, you can see it sticking out behind the left wheel of the right truck of the left bolster, pointed at the end of the car. Above that, you can see what looks an air tank of some sort? maybe?  I can't see any evidence of this in any other sources. Note that, as I said, the cylinder appears lower than Chuck's mount because its centerline is below that of the wheels and the bottom of the span bolster. That makes sense, since there was undoubtedly brake rigging under the span bolster, as you can see by the rodding under the bolster in the photo of 470202

2) Between the trucks on the right hand span bolster you can see the AB brake valve. That appears to be affixed to the body of the car. You can, in part tell that by looking at my TKM article about the decks. Looking at the deck pattern, you can see that, as you stand at the end of the car, the pattern of tie-down holes is interrupted on both the end deck panel and one panel in on the left side by bolts or rivets. The two bolts/rivets on the second panel in are, I presume, are the location of the mounts for the AB valve. 

3) The 4 bolts on the end deck panels are for the two air tanks, as shown in the F&C instructions, with the shorter tank outboard of the longer tank.

4) The retainer is on the side of the car at the right end.

5) Both sides are identical.

For more resources, here's an old brass Westside car posted by John Sethian
I have no idea what is going on with what looks like a K brake reservoir on the body... that should be an AB valve, but the rest of it seems to follow my surmises... including brake rigging under the span bolsters!

           Thank you for your response. I have referenced the TKM articles. Unfortunately they do not show any of the duel brake arrangements. F&C is very vague on their instructions. I referenced my 1940 car builder cyclopedia as well with no luck. I'm not going to super detail the underside as it is not visible. However some of the brake detail is visible in some photos, but not clear enough to see how they are arranged. I have no idea how to arrange the brake components parts onto the span bolsters? There are no indications on them to show as to were the parts mite go. F&C just states install them when you get to this point. You mentioned the PRRT&HS flat car book do you know if the book provides any kind of brake arrangement for the cars? If I knew the book listed them I would look for a copy as I don't currently own one. I believe the society has sold them out.

          On another note I did find out that the D&H version of this car that I posted a question on a while back is the same car as a NYC car. They showed up in my 1953 car builders cyclopedia. Both were built 1951.

Good Day
Dave

Dave,

Some resources:
TKM 104 - http://www.prrths.com/newprr_files/newPRRKeystoneModeler.htm  this is an article by Chuck Cover kit bashing the Bachmann car, but it will show you gross brake locations. 

TKM 108 - My article on etched decks. Not much about brakes here, but if you look at the deck drawings, you can see the mounting bolts for what I believe is the AB valve.

The PRRT&HS flat car book - http://www.prrths.com/estore/index_books.html
Sadly, the shots in that book are mostly dark about the underbody.


Based on looking at the photos online (above) it looks like Chuck has his cylinder mounted too high on the bolster and he needs to add a reservoir to the bolster.

And, of course, you need a full set of brake hardware on each end.

Hello Guy's
                   I'm currently building a F&C PRR F34 flat car. The instructions are very vague about the placement of brake components. If anyone has any info on the placement of the brake parts I would deeply appreciate this as I'm at a stand still with this car. I know some of the parts are to be installed on the span bolsters but I'm not sure of their placement. Thank's

Good Day
Dave
