PS-1 BOX CAR RESOURCES
 

Kaslo Shops introduced an S scale urethane resin 40 PS-1 box car in 2003 (now OOP.) This was a very common car design built from 1947 until 1968 and used by numerous roads, but it did have several design variations over the time frame in which it was built. The purpose of this page is to organize in one location some modeling and prototype data to assist S scale modelers with this model. In order to keep this as useful as possible, I have generally limited the data to the prototypes that the Kaslo Shops model represents (40 IL, 6 door, tabbed side sill, welded sides) and for which there is S scale lettering available, primarily CDS dry transfer lettering (all of which I sell for $3 postpaid,) but also Clover House and Greg Komar dry transfers, and Oddballs and John Hall decals. Note: the sets listed below may not be specifically intended for PS-1 box cars, but do have appropriate heralds. In some instances dimension data could be off (10 IH instead of 106 IH, for example.) If you are aware of any other available lettering appropriate for PS-1 box cars, please let me know and I will add it to the list. Any errors in the data below are mine; the information was taken from Ed Hawkins' 1993 RMJ PS-1 series. I highly recommend getting copies of those profusely illustrated articles or obtaining other suitable photos for verification. If there is anything else I can help with, please feel free to ask.

 
 
Summary of Modifications:
_______________________________________

        Unmodified model (with optional 3rd cross bearer) represents car built after mid 1954.

        Narrowing the bolster sill tabs (and adding optional 3rd cross bearer) backdates it to be appropriate for cars built between (50?-52?) and mid 1954.

        Installing only 2 cross bearers (and modification above) backdates it to be appropriate for cars built from 1950 to (50?-52?)

        Removing raised panels in the roof end sheets and mounting the side bracket grabs so that they are supported by the end sheets (and modifications above) backdates it to be appropriate for cars built in 1949.

        Removing the 6 small rectangles from the ends (and modifications above) backdates it to be appropriate for cars built between 1947 and 1948.
