B&O 2-10-2 Big Six
Baltimore and Ohio Class S comprised two classes of 2-10-2 locomotives.
The S class proper were 31 locomotives built in 1914 by Baldwin Locomotive Works and numbered 6000–6030. The S-1 class comprised 125 locomotives numbered 6100–6224. They were built between 1923 and 1926, 75 by Baldwin and 50 by Lima Locomotive Works (#6150–6199).
They were nicknamed "big sixes" because of their size and because, until renumbering in 1954, their road numbers all began with "6".

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
F4- Coal Fill [looping while F4 ON]
F5- Steam= Waterpump turbine
F6- Bell and [This project changes F6 for switch speed.
With F6 on the motor will be slowed by about half when CV54=1.
Bell is disabled by F20
F7- Steam=Blowdown ; if CV155 is not 0
F8- Mute control, [F8 ON is muted.]
F9- Brake squeal till stopped -- Leave oFF to enable auto brakes
F10- Crossing gate Whistle sequence
F11- Water Tank Fill [looping while F11 ON]
F12- Wheel Squeal
F13- Steam=Safety Blowoff
F14- Cylinder Blow Down [F14 ON will disable cyl. blowdown ]
F15- UNCoupling [Leave on for auto toots]
F16- Stoker, shovel [Grate is on when F23 OFF]
F17- BOX car Boom
F18- Steam Greaser
F19- Coal Grate Shaker
F20- Air feature disable- F20 OFF enables pop-off,starts airpump
F21- Disable BELL for switcher mode F6, TOOTS for exit idle
F22- Disable WHISTLE on distance event
F23- Select Coal Stoker when OFF
F24- Crossing gate Whistle sequence; Steam=Wheelslip, ;if CV155 is not 0
F25- Disable hard auto brake
F26- Use Articulated Cylinder 2 Chuffs

(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.
All sounds taken from existing sound projects.
