Re: Mystery Tank Car

Mark,

Not quite.  The casting integrated the bottom of the tank with the underframe, replacing the traditionally separate structures with a single part that both carried the loads and formed the bottom course to contain the liquid cargo'  This lowered the height of the car and allowed the very large 16,200 gallon car to fit in the then extant clearance diagrams.  Three additional conventional plate courses were riveted to the cast underframe to form the tank.  The Tk-L class came from General American with the Ajax power hand brake, KC airbrakes, and 70 ton one-level Dahlman trucks.

I found the photo on page 392 of the 1937 CBC.

However the drawings make it look like there is aconcave shape to the top of the cast to allow the tank to be cradled.

Jon,

From the ATSF Tank Car book pg 71 the GSC one piece cast tank bottom/bolsters/draft gear appeared in the 1937 CBC.

If the casting came from Commonwealth
    One of the CBCs has a picture of the casting but can't remember the year off the top of my head.  Doubt anyone is going to pay those prices for the drawings.
