A while back there was some discussion about the USNX/ATMX 30 tube helium tank cars built by GATC and ACF.
Does anyone know what the diameter of the tanks were on these cars, please?
The drawing on page 12 of Jay Miller's excellent Helium car clinic handout;
"A Portfolio of Helium Tank Cars 1926 - 1962"
seems to show a tube diameter of 18.5in for USNX 1054.

I'm not sure if it is safe to extrapolate this to other cars...
