Steam Operation Overview Overview

• Overview Tsunami2 Steam • Review all functions and effects in decoder that set us apart • 16 independent sound channels allow faithful replication of sound • Show how they relate to operating the prototype • Add more fun! How a Steam Locomotive Works Setting up the Sound Configuration CVs

• CV 112 - Adjusts fuel type, injector, and cylinder count • CV 114 - Adjusts the chuff rate • CV 120 - Selects the whistle • CV 122 - Selects the bell and ring rate • CV 123 - Selects the exhaust chuff • CV 124 - Selects the air compressor • CV 125 - Selects the dynamo CV 120 • Selects the whistle • 90 Choices in NEW Steam-2 • Sound roster found at SoundTraxx.com-> Reference-> Manuals • Volume set in CV 129 CV 122 • CV 122 selects the bell and the ring rate • Set CV 122 = 12 for medium brass, medium ring rate • You can choose from 12 bell options • 54 total recordings when factoring in ring rate • Volume set in CV 130 CV 112 • Bits 0-1: Select fuel type • Hand fired coal, wood, oil, coal fired with auger • Bit 2: Selects type of injector • 0= Non-lifting (default) • 1= Lifting • Bit 3: Selects manual vs. power reverser • Bit 4: Enables a 3- cylinder locomotive chuff cadence • Bits 5-6: Sets an articulated exhaust slip rate • Bit 7: Enables an articulated chuff

• To match our locomotive we are going set CV 112 = 3 • Auger-fed fired coal, manual Johnson bar with a non lifting injector, 2-cylinder locomotive CV 114

• Calibrates auto chuff rate with new motor load synced chuff rate • 4 chuffs per revolution at all speeds • 0-255 for chuff rate • For the Atlas O-Scale model set CV 114 = 45 to get an accurate 4 chuffs per wheel revolution • New intelligent exhaust chuff effect for more realistic sounding exhaust at higher speeds CV 123

• 10 different exhaust chuffs including • 3 Light • 3 Medium • 3 Heavy • Geared • Set CV 123 = 2 • Light Steam #3 • Also selects different blower (Discussed later) • Volume set in CV 131 Factors for the Chuff

• Cylinder count 2, 3, and 4 are all in both the Tsunami2 and Econami • Dynamic Digital Exhaust adjusts the intensity and tone of the exhaust chuff. • Tsunami2 equipped with throttle-based and reactive DDE • Econami only throttle-based DDE Calibrate Dynamic Digital Exhaust

• Run the model for at least 2 minutes before starting the process • Set CV 32 = 2 to access the second index (location of the DDE CVs) • On a flat, level track without any load behind the loco, perform the following steps: • With model at speed step 1, set CV 2.503 = 255 • Increase to speed step 25-30 (of 128) • When model reaches that speed, set CV 2.504 = 255 • Adjust CV 2.512 to your liking to further tune the exhaust chuff effect response to changes in load or grade. Set CV 2.512 = 64 Steam Default Function Assignments

• F0(f) Headlight • F15 Wheel Chains • F0(r) Backup Light • F16 Water Stop • F0 Dynamo • F17 Fuel Loading • F1 Bell • F18 Ash Dump • F2 Whistle • F19 Wheel Slip • F3 Short Whistle • F20 Injector • F4 Cylinder Cocks • F21 Sander Valve • F5 Cutoff+/Drift Enable • F22 Cab Chatter • F6 Cutoff- /Drift Disable • F23 All Aboard!/Coach Doors • F7 Dimmer • F24 FX3 Function Output • F8 Mute • F25 FX4 Function Output • F9 Grade-Crossing Signal • F26 FX5 Function Output • F10 Blowdown • F27 FX6 Function Output • F11 Independent/Train Brake • F28 Not Assigned • F12 Brake Select/Train Line Charge • F13 Couple/Uncouple • F14 Switching Mode Working Cutoff • Tsunami2 steam now has adjustable valve cut-off through either a Johnson bar or power reverser. • Function 5 simulates shortening the amount time steam is emitted into the cylinders with a shorter, higher-pitched exhaust chuff sound effect. • Function 6 simulates lengthening the amount time steam is emitted into the cylinders with a longer, lower-pitched exhaust chuff sound effect. Drifting Effects • The last notch of the adjustable cutoff allows more accurate depiction of drifting down a long grade • New drifting sounds include: • New rod clank sound effects • Leaky valve packing sounds • Lifting and dropping snifter valves Wheel Slip

• New to Tsunami2, pressing Function 19 will enable a wheel slip feature • The engineer will recover by shutting off the throttle then slowly re-opening the throttle • This is typically heard when a locomotive is first starting up or when a heavy train is running on a wet rail Steam Dynamo and Lights

• Function key 0 turns on both the dynamo and the headlight/backup light • On prototype steam locomotives, all electricity is provided from a steam driven electrical generator usually located on top of the locomotive boiler known as a dynamo • Tsunami2 allows you to select dynamo in CV 125 • Dyno-light Hyperlight effect increases the light’s brightness coordinated with the sound of the dynamo winding up • Volume set in CV 133 Cylinder Cocks • Activated using Function 4 or can be set up to be automatic • On the prototype, they are used to blow out moisture collected in the cylinders of the locomotive after sitting idle for some time • Typically used if engine has sat for longer than 10 minutes • Unlike competitors feature, can be activated at any speed • Volume set in CV 136 Steam Blowdown Valve

• Function 10 opens the blowdown valve • Used to help regulate water level if it is too high and to clean out impurities in the boiler • Volume set in CV 144 Independent and Train Brakes • Function 11 activates the brakes in the locomotive • Tsunami2 supports both types of brakes found in a steam engine • Independent Brake (Locomotive Brake) when Function 12 is off • Train (Automatic Brake) when Function 12 is on Independent and Train Brakes

• Toggle between braking types using F12 • Turning on F12 will “charge the train line” triggering the air pump to cycle at a rapid pace • Independent brakes play sound of engine brake squeal • Train brakes play the sound of an air reduction known as an application or set • Both play unique sounds of a release when function 11 is turned off • Brakes may be configured to affect speed of the train or simply play the sound effects • Uses CV3, 4, 117 and 118, Volumes in CVs 138, 139, 140 • When paired with SoundCar, creates a great train effect Servicing Functions • Function 15 is wheel chains being placed • Steam equivalent to a hand brake • Function 16 is the water stop • Fills tender with water for as long as function is active • Function 17 is fuel loading • Steam engine can be set to fire coal (hand fed or auger), oil, or wood • Function 18 is the ash dump • Plays sound of opening ash pan and shaking grates • Sound of an air wand will also play • These functions allow the modeler to add realism to hostling and servicing their locomotives Injectors

• Function 20 and Fireman Fred will turn on the injectors for the boilers • Used to add water into the boiler • locomotives are equipped with two methods of adding water to the boiler, of which at least one is an injector • 2 types of injectors • Lifting • Non-lifting • Volume set in CV 147 Sander Valve

• Function 21 is the sander valve • Sanders are used to give traction on the wheels of the locomotive • They can also slightly slow a locomotive down by putting small amount of friction on the rails • Volume set in CV 154 “Cab Chatter”

• Function 23 turns on sound of a radio conversation • Conversation is recorded from real railroaders • Many recordings and special algorithm to ensure non-repetition • Most chatter ideal for modern day operations • Can be automatic Fireman Fred feature/sound effect • Volume set in CV 160 Other Sounds Explained

• Air Compressor or Air Pump (selected in CV 124) Used to supply air for brakes, bell, Sanders. • Activates based on how you use loco • Volume set in CV 132 Other Sounds Explained

• Snifter • Allows remaining steam to vent out of cylinder • Used to prevent build of steam from leaking throttle potentially causing undesired movement of the locomotive when sitting still • Activated when first speed step command is given to the decoder • Volume set in CV 141 Other Sounds Explained

• Blower • Used to create an artificial draft in boiler when locomotive isn’t working or moving enough to create a natural draft • Paired and selected with exhaust chuff • Volume set in CV 134 Other Sounds Explained

• Safety Valve • Set to prevent boiler from reaching pressures too high • ‘Pops’ off • Very loud • CV 208 sets probability • Volume set in CV 143 • Other Fireman Fred sounds • Wrenches • Grease gun • Injector and more! Other Sounds Explained

• Rod Clank • Sound of the main rod knocking against the crank pin • Sounds of the valve motion • Sound is present when locomotive is moving but more prevalent when coasting or drifting • DDE affects sound • Volume set in CV 135 How to start a steam locomotive

• Turn on Headlight/Dynamo (F0) • Blow proper whistle signal (F2/F3) • Throw Johnson Bar forward (Direction/F5/F6) • Turn on bell (F1) • Open sander valve (F21) • Open cylinder cocks (F4) • Gently open throttle to pull out coupler slack (Throttle Knob to SS1) • Release independent/train brake (F11) • Adjust cut-off by moving Johnson Bar back towards center (DDE, F5/F6) • Close Sander valve (F21), Close Cylinder Cocks (F4) • Open throttle to get moving up to speed (Throttle Knob) Conclusion

• Understanding steam locos is key to Tsunami2 development • No sounds are lost because other sounds play • Running trains can be more than just adjusting the throttle knob • Using the steam loco more like the prototype makes operating sessions more interactive and more fun! Floobydust
