Re: [CBQ] Diaphragms

[Bob Webber <rgz17@comcast.net>]

FWDs were basically outer curtains, there was always an inner diaphragm incorporated.   When a car w/o FWD showed up, it made no real difference, though the outer curtain could be floppy.  There were retainers to hold them and keep them blousing in the airstream.

A couple of us are having a discussion about the full-width diaphragms applied to the post-war Zephyr trainsets and the question arose as to how these consists were amplied with additional equipment as needed. That is, could narrow diaphragm cars be mated cars with full-width disphragms? Or were all of the lightweight cars initially equipped with full-width diaphragms? A related question, I suppose, is when were the full-width diaphragms removed?

Thanks,
