Hi,

I'm going to build two Sunshine kit's (#96.9) for 40' Autobox car and four D&RGW 40' twelve panel box cars. I have a problem with the construction of the brake system. The kits comes with one building instruction for AAR 1942 and 10' IH 1944 boxcars and one Added Modeling notes for the cars in question.

The building instructions shows an ordinary AB brake system bur the Added Modeling notes shows a AB system with a Royal F slack adjuster. I can't figure out how this brake systems works and I'm unsure if the pictures in the in the modeling notes are correct.

Can anyone point me to a prototype photo of this type of brake system or any other information that will show me how it works and how it should be put together.

Sorry for cross posting this on two lists. I'm eager to get an answer and start building the kits.

You can find an excellent handout in the file section for the group, its called: Freight Car Underbody Detail by Gene Green. An illustration of a slack adjustor is on page 14. It was added to the files by Doug Harding on April 3, 2009.

Its one of my most used files! I keep it in a folder near my workshop desk.

Roland, I'm sending you off-list a page from the 1940 Car Builders'
Cyclopedia which describes and illustrates the Royal F slack
adjuster. It should answer your questions.

Thanks Gary for directing me to the handout. It's a great help for anyone
interested in modeling the underbody details. Thanks also to Richard and Tim
for the information you provided. I'm still not sure if the photos of the
brake system in the modeling notes for the kits are prototypical correct.

I took two photos of the illustrations in the modeling notes and posted them
to Photos section in the folder "Brake system Sunshine D&RGW boxcars". They
are awaiting approval. I intend to remove them as soon as this this topic is
finalized to avoid any discussions about copy right. I would appreciate if
anyone could look at them and give your comments. I suspect that the two
levers could have been mixed up and I think the angel of the center rod
looks strange. I would also appreciate if anyone could confirm that this
location of the slack adjuster is correct or at least plausible.

Best regards
