Re: IC GS gons



I wondered about the strength of the side assemblies get the loads thru the body bolster when being clamped in a dumper and then tilted or rotated.  The earlier cars had very rigid, continuous stable timbers along their side assemblies.  With a steel side structure we are looking beams and shear plates to handle these loads.

Was there an angular center sill cap to divert the coal thru the openings or was it flat a foot plus across?

The 1905 era gons with drop doors didn't have doors over the trucks, so weren't "self clearing" and still required men to shovel about half the load out through the doors.
That depends on the car in question. The Ralston GS gons certainly did have doors over the trucks, as did some Cambria cars of that era.

The broader point about the volume used by the customer is valid, though it should be tempered by era. The stereotypical GS gondola with a full complement of drop doors appeared just after 1900 (once steel framing made it practical), and initially found buyers in coastal New England, the Midwest, and most roads that made it to the Pacific. After 1915 or so, the range of purchasers steadily retreated westward so that the Pacific roads were about the only large buyers after 1950.
