(C) General Notes

This sound recording courtesy of Arkansas and Missouri Railway Short Line Scenic railroad and Kenny the
Maintenance Manager,
Visit arranged by Loy Spurlock.
All sounds recorded by AJ Ireland at Springdale AR, June 23rd 2007.

Note:  This RS32 prime mover has significant low-frequency components at idle and low notch settings,
so the speaker enclosures should be as large as possible behind the diaphragm to extend adequate frequency response below
e.g. 300Hz. This will ensure a more "full" sound that does not appear thin or "tinny".
 
Each engine we have recorded has a distinct 'personality', so a particular locomotive example may sound slightly different
due to unique e.g. tappet, crank-rate shell vibrations and exhaust-stack differences. Horns and bells are often moved between locomotives, and
some roads may change/upgrade prime-movers, or change a normally aspirated engine with turbo-chargers etc.
Recording aspect and location reverberation also significantly affect the final sound scheme impact.


For CV155=01 ["Semi_automatic Notching"],  the Prime mover lowest Notch setting is set by
 the throttle speed setting. F6 (ON) can increase the Notch and F7 (ON) will decrease the Prime mover
to the minimum notch set by current throttle setting.
If you leave F5 on, you can wind the engine handbrake forever!!
