Compressor Options - MagnumMacKivler/RLCPT2 GitHub Wiki

What are they?

Often builders offered alternate options to the stock compressor offering, normally of a larger size. This page is geared towards helping you figure out the proper CFM if you wish to use one of these options, as they don't scale linearly.

Below will be provided with brief descriptions of the compressors and their corresponding curve equations, you will need to insert the engine RPM, which can be found next to the CFM listed on a locomotive wiki page.

Wabco 3CD

Description: A common compressor used in older locomotives due to it's larger size; virtually the same as the 3CDC, it's only major difference is the cylinder's stroke.

Equation: SCFM = RPM*0.307

Wabco 3CDC

Description: The go-to compressor if you didn't want a Gardner Denver product, they were often found inside of Alco's and FM's locomotives.

Equation: SCFM = RPM*0.225

Gardner Denver WBO

Description: garbage

Equation: SCFM = 0.000125(RPM)^2+0.17(RPM)

Gardner Denver WBG

Description: junk

Equation: SCFM = 0.000125(RPM)^2+0.332(RPM)
