Re: Shrouded tank cars: floors?

Steve and Barb Hile

The Monsanto car in St. Louis does not have a floor under its hood.  A photo is attached.
It is my belief that such cars, in general, did not have floors.  The hood (shroud, etc?) often covered heating coils that were external to the tank due to potential issues relating to the interaction between the tank contents and any escaping steam/water.  UTLX pioneered such a car circa 1914 for carrying paraffin wax.  Later uses included transformer oil.
The Monsanto car does not have heater coils, however.  So that it could also be related to trapping noxious gases.
More than you asked for, but less that definitive.

Subject: [RealSTMFC] Shrouded tank cars: floors?

There were some tank cars with shrouds (for insulation?) that curved across the top of the car and then went down vertically to the cars' running boards. Examples are on p. 18 of Jim Kinkaid's Tank Car Color Guide volume 1 (Morning Sun) and one, a Monsanto car, is preserved at the transportation museum in St. Louis. Ambroid's old Riverside Oil Company tank car kit is another example. But my question is this: did these cars have full floors, or was the car open frame like any other tank car? Or maybe partial floors?

And no, these are not removable containers like on the butterdish milk cars.
