Thanks for these responses. If the curling and sealing problems manifested
themselves within 2 years causing the BRE to revert to tongue & groove, and
with plywood having been used in this manner from 1935 onwards, one wonders
why plywood was used for these cars in the first place. Perhaps the
designers thought they had solved the problems. Alternatively, they
perceived the advantages to outweigh the potential problem.
Plywood was widely used in World War II and supposedly had been much improved. The "Douglas Fir Plywood Association" promoted it widely for many uses, from homebuilding to freight car exteriors (and interiors, where it was satisfactory). Perhaps the plywood of the late 1940s was no better than 1935, but evidently people thought it was.
