Re: Retirement Plans for R44/46?

Both the R-44 and R-46 had no feed valves - pre GOH (IIRC) and both operated with brake pipe pressure of 135 - 150 PSI. The difference was & is that R-46s had WABCO D4S compressors while the R-44 was originally delivered with a WABCO D3 compressors that were replaced by Knorr units. The knorr units leave a little to be desired.
