Building a WWII ATSF fleet II—Boat Flats



Continuing on my quest for an accurate model of the Santa Fe’s Bay area operations, I was motivated by a post on the Rail Marine Yahoo group to re-look at my references for boat flats.  The railroads used idler cars to reach cars on the car float without putting the heavy engine on the ramp or float itself.  This was more for traction and balance rather than ramp or float capacity as the engines at San Francisco and Oakland’s Alice Street routinely transited the bay on floats to their shoppings at Richmond.  It was important though, to maintain balance on the floats, and using idler cars as a handle to reach cars on the back of the float allowed that balance to be more easily maintained.

My principle source is the Work Equipment Car book by Bill Childers published by the ATSFH&MS.  It can be ordered from the society at http://www.atsfrr.org/store/bookFrt.htm, although at this writing it is currently out of stock.

I am an engineer and analyst and find it much easier to gain insights if I can rearrange data and look for patterns.  To that end, I transcribed the data in Bill’s book to an Excel spreadsheet.  I find spreadsheets are a good way to manipulate the data and add information from other sources.  Using the class and former number info from the Work Car table, I added former class info from the Live List.  This allows the modeler to make a good stab at the under frame and side sill configuration without a picture.  Bill lists 64 unique cars in the series of 191700-191749 which were assigned to boat flat service.  Most would have been used at Richmond and other Bay area points, but their was a Gulf Coast operation between Galveston and Port Bolivar Texas that operated in the late 30’s.  The cars in Bill’s table listed as converted at Port Bolivar almost certainly operated there. 

Based on the former car numbers and class information, you can infer the identity of the donor cars.  Further work is needed to determine the original cars for the work cars converted to boat flat service.  For those converted from cars with revenue numbers, the following classes were used as boat flats during the period that they had dedicated boat flat numbers.
Ft-, Ft-G, Ft-H, Ga-V/Ft-G could have been used with minimal or no modification.
Bx-B, Bx-13, Bx-D, Bx-O, Bx-W, Fe-L, Rr-R, Rr-S, Sk-H, Sk-V, Sk-W were former house cars that most likely were cut down to their floors and used as flat cars. 

But which of these cars operated in my era?  To answer that question I used the sort feature in my transcribed spreadsheet to separate the cars that had disposition dates after the 1943.  And here are the results:

These are my candidate cars for Bay area boat flats during WWII.  All the others had been retired or converted to other purposes before 1944.  The Galveston operation had closed down by then and some of the Galveston cars may have migrated west as the Sk-V based flats that retired at San Francisco and Richmond seem to indicate.  This is an interesting mix of older flat cars, cut down box and refrigerator cars, and purpose built cars from scrap materials at the Richmond Shops.
