B&O 2-10-2 Big Six

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".

Project: B&O 2 10 2 Big 6 for 16 Bit series 6 use
SDF:  mySteam ver 11 John McMasters
Author: Barry T Gaskin

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[63]
    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.
        
     New Features:
         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 [0]

(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.
