NKP 587 2-8-2 Mikado class H6a USRA Light Steam
Nickel Plate Road 587 is a USRA Light 2–8–2 steam locomotive built in September 1918 by the Baldwin Locomotive Works for the Lake Erie and Western Railroad as its number 5541. In 1923 the LE&W was merged into the New York, Chicago and St. Louis Railroad, (“Nickel Plate Road”), and allocated 587 as its new number in 1924. The locomotive is currently being restored by the Indiana Transportation Museum.
NKP No. 587 is generally referred to as a Baldwin locomotive. However, her supporting truck and cylinders are actually from another Lima Locomotive Works (LLW) engine when the original cylinders failed. 587 is the best remaining representation of the Mikado 2-8-2 locomotive style originally designed and built as part of the World War I rearmament program.

Generic heavy steam loco use to replace your sounds for your specific model.
NOTE: Assign silence to cylinder 2 sounds when CV155 NOT =2 (Save memory---handles are not played
unless project is running "Articulated" sounds with both front and rear cylinders.
NOTE: Make sure that the model CV133 Steam Chuff/CAM config, 128=>EXT cam, 1-127=>DRIVER dia in inches
and CV134 Gear ratio are adjusted so that THERE ARE 4 STANDARD NON-ARTICULATED
CHUFFS PER REVOLUTION. ARTICULATED SOUNDS ADD AN ADDITIONAL 4 CHUFF SOUNDS TO THE MIX.
g) on reversal clash with F15 and/or F11 is
on [F15 off + F11 off = no extra sounds]
[F15 on + F11 on = all extra sounds]
[F11 controls auto clash and uncouple]
[F15 controls auto clash]
h) auto rod clank cyl blow down (steam cocks open)
will coast after deceleration for up to 5 cycles playing ALT_RC
i) coal grate
j) coal chute
k) auto brake on decelerate (two rates hard and short)
F9 Leave off to disable auto brakes
l) optional cylinder 2 sounds varied; Set Slip mode=1 OR F26 ON (Articulated Cylinder 2 Chuffs)
CV155 Notching/Slip Mode,0=AUTO, 1=(ARTICULATED) SEMIAUTO,2=MANUAL NOTCHES 
(see all features below);
(A) Function Key Usage:
F2- Horn/Whistle [CV150 selects Horn/Whistle type]
F3- Coupler crash; Auto Coupler coupler clank and BRAKE if F3 is ON, is dir chng and last PK spd below e.g. CV151
[Autocoupler/brake set by CV151 max spd] F11 on for un-coupler
[Leave F3 on for auto coupler]
Toggle OFF plays directional toots
F4- Steam=Safety Blowoff
F5- Steam= Waterpump turbine
F6- BLOWOFF/drier then air pump ONE time
F8- Mute control, [F8 ON is muted.]
F9- brake squeal [Leave F9 off for auto STEAM BRAKES]
F10- Crossing gate Whistle sequence [Bell stays on until F10 off]
F11- UNCoupling [Leave on for auto toots]
F12- Wheel SQUEAL (continuous when moving) [Disables bell on F6]
F13- Coal Fill
F14- EStop when moving and Shutdown (disables motor movement until OFF)
F15- Water Tank Fill
F16- Grate shaking,ash dump
F17- BOX car Boom
F18- Steam Greaser
F19- Grate Shaker

(C) General Notes
Low speed: A standing Locomotive collects condensed water in its cylinder as trapped steam cools. Since it isn't
Compressible, this water can blow out a cylinder head when the engine starts.
To avoid this ,the engineer first opens valves called cylinder cocks under each end of the
cylinders(sometimes in the middle too ). Then when the engine starts,the exhaust steam comes
Whoooshing out of the cylinder cocks with the condensate instead of chugging up the stack.
Engines doing this spray steam from under their cylinder.
The starting steam cock open is controlled by CV147 (about =14) since steam loco has no drier.
