SCS CN Values for Railroads

SCS CN Values for Railroads

SCS CN Values for Railroads

(OP)
I'm working on estimating a composite CN value for a large drainage area with various cover types that include railroad tracks. Does anyone have guidance they can share, or recommend a CN value to use, for railroad tracks? I'm referencing Table 2-2a in TR-55 but there does not seem to be a cover type that describes railroad tracks.

I appreciate any and all assistance in advance.

Thanks,
Scott
