“Full Throttle” Decoder Operation for Diesels

It is often challenging to make a scale model preform like it has the mass of a 260,000lb locomotive pulling 5,000 tons or more! Some of this can be done with BEMF - when the loco “feels” a load, it will automatically rev up to work harder to pull this actual load. But this is often a flawed method in modeling. Today, model train car wheels are so free rolling that they often do not simulate sufficient drag to replicate a typical prototype situation. Also, often we do not sufficiently weigh our cars to represent a scaled-down version of the prototype. One of the biggest problems with BEMF controlled load is due to the fact that in our modeling and operations we often “simulate” loads inside a closed car. The payload inside a prototype car can weigh as much as 100-tons more than the car itself. This is especially important at operating sessions. Empties in and Loads out or vice versa. There is no way for a decoder to know the proposed weight of the cars it is pulling. Our “car cards”, showing whether a car is loaded or empty, are seen only by the operator, not by our decoders!

To compensate for what the decoder cannot know, we have created Full Throttle decoder features! This series of new features includes “Drive Hold”, “Run 8”, “Coast”, improved “Dynamic Brakes” and a new “Independent Brake” feature.

Drive Hold:

This feature allows the modeler to easily simulate a loaded or empty train by adding a single “Drive Hold” function button. When the button is pressed, the motor will remain at a constant speed, while the sound can be controlled independently from the motion with the throttle knob!  This exciting, new feature gives the operator the ability to have his or her train crawl in notch 8 or coast at 50mph. Then, by releasing the Drive Hold function button you simply go back to throttle-controlled speed and motion. No more switching between manual notching and programming on the main to go back and forth. All of this can be done on the fly with hardly even thinking about it.

Run 8:

There are times when hauling a heavy train over rolling hills that you may wish to remain in notch 8 at any speed desired. You could have the train slow, as it climbs a steep grade and then speed up upon levelling out. The Run 8 feature will allow for exactly that. Simply press the button and the prime mover will increase RPMs from wherever you are, all the way up to Notch 8 and hold. Once the function button is pressed, the sound is disengaged from the speed. Using the throttle knob you can now speed up or slow down with the sound remaining constant, at full throttle.

Coast:

The opposite of “Run 8”. Often when coming to a stop, the throttle of a real locomotive is put into Idle and the engineer coasts to a stop. Another situation that occurs is that once a train is up to speed when operating over rolling terrain, the engineer can coast to maintain a certain speed. By pressing the coast function button, the sound drops from wherever you are to idle and remains there. Once this function button is pressed, the sound is disengaged from the speed. Using the throttle knob, you can now speed up or slow down the train with the sound remaining constant, at idle.

Brake:

Along with Dynamic Brakes, a locomotive has an Independent Brake as well. This allows for the locomotive to stop more quickly than its regular momentum would normally carry it. LokSound Decoders now also have a working Independent Brake. This one is pretty self-explanatory – just press the brake and come to a stop! While this will work with whatever deceleration settings are in the loco, it tends to work more realistically if the loco has a large amount of deceleration. With these settings the loco will drift or coast much further when the brake is not applied. Then, by applying the brake, the loco will stop in a much shorter distance. As a note, you can now do standing brake tests by keeping the brake on and advancing the throttle knob so the sound of Notch 4 can be heard. In EMDs this is the point at which the Shaft-Driven compressor reaches its second stage, and pumps air faster through the train.

Dynamic Brake:

The ESU Dynamic Brake works like the prototype. Once applied, the sound will drop to idle. Then (once the electricity dissipates from the traction motors) the prime mover will rise depending on the prototype. Most EMDs rise to about notch 4. Other brands will vary. Once the prime mover comes up, the dynamic brake fans will be heard. During this time, a deceleration will be quicker since you “have your dynamic brakes on.” Once you release the button the fan will shut off as the prime mover drops again to idle. After a short delay the prime mover will once again come up to match the speed of your throttle - (other Full Throttle features may affect where your prime mover sound returns after the dynamic brake is turned off.) Please note, if you come to a stop when your dynamic brake is applied, the fan sound will cease and the prime mover will go down to Idle. You will need to turn it off before you begin to move or the cycle will start again. Prototype locomotive dynamics will not work while stopped.

The ESU Dynamic Brake has not really changed much with the new added features. But the new files will now work better when consisted together and using the Dynamic Brake. Also since not all locos have dynamics, you will now be able to set up your non-dynamic locos to work correctly with consisted locos using dynamic brakes. The ESU Dynamic Brake Logic Feature does increase the deceleration rate so please take this into account. If your loco does not have dynamic brakes you should still apply the “Dynamic Brake” LOGIC when consisting so that the engine slows with other dynamic brake-equipped locos in consist. If your loco is not equipped with dynamic brakes please choose Sound Slot 21 (Coast) for the sound on the dynamic brake function button. This will have your loco drop the prime mover sound to idle while the dynamic brake-equipped locos in the consist go through the dynamic brake cycles. You should not use the “Shift” logic with non-Dynamic brake locos. Doing so will result in the prime mover rising up to Notch 4. This is not correct for Non Dynamic Brake Locos in a consist. It needs to stay at idle.

We are proud to present to you the brand-new LokSound Select decoder. The LokSound Select decoder was designed with all our past experience, while considering many suggestions of ESU users.

The LokSound Select is a versatile DCC & DC “Dual Mode” decoder integrating a full-featured, 8 channel sound system, six lighting outputs and a 1.1A motor controller. While the LokSound Select only measures 1.18” x 0.59” (30mm x 15mm), due to its unique thermal design, it does (like all genuine LokSound decoders) not need any heat sinks.

We ship the LokSound Select with an 8 pin NMRA connector to make it a “plug & play” decoder. It also contains on board capacitance for smooth operation. For LokSound Select, we offer a comprehensive range of new high-power speakers, rated 4 Ohms.

Operational modes

The LokSound Select can be used on conventional “analog” layouts and controlled with a DC power pack, but to benefit from all its features, we highly recommend DCC operation.

The LokSound Select follows all NMRA DCC standards and recommended practices. It can be used with 14, 28 or 128 speed steps, supports two digit (7 bit addresses) as well as “4-digit” addressing. Up to 29 function keys are supported. The LokSound Select can change between DC and DCC operation at any time “on the fly”.

Of course, the LokSound Select supports all DCC-programming modes including Programming on the Main Track (“POM”). Because of its unique low-power design, the LokSound Select can be programmed on the programming track of all popular DCC systems. No programming track boosters or other circuitry will be needed.

By the use of our LokSound Programmer, programming can be even more comfortable by using your computer to adjust the many CVs and settings.

Sound

The LokSound Select comes with a 32 MBit memory chip. The sounds stored therein are our own recordings which were made by using the latest recording equipment and have been digitally re-mastered for the best audio possible. The sounds are transferred to a class “D” audio amplifier via eight polyphonic sound channels. LokSound Select decoders offer the following unique features:

  • Multiple whistle and horns: Each LokSound Select offers many whistle & horns. By just changing one CV, you can select your favorite one. This allows an easier adjustment to your model.
  • Playable whistle: The LokSound Select supports a very fast responding whistle function. By just pressing your throttle‘s button, you can really blow the whistle like the real engineer.
  • 8 channel sound: The LokSound Select can playback up to 8 sounds at the same time. This will result in the most realistic experience available today.
  • Synchronized brake squeal: The LokSound Select will synchronize the brake squeal sound with the real movement of the locomotive. No longer will stopped trains have the brake sound still on!
  • Manual notching: The diesel speed steps can be either manually controlled by function keys or automatically based on the speed.
  • Individual volume control: The volume of all sound effects can be adjusted individually.

Steam decoders can produce over 20 sound effects, including the bell, air pump, exhaust chuff, coupler, steam release, cylinder cocks, brake release, side rod clank, blower, injector, Fireman Fred and many more. Synchronizing the steam chuff rate by using two CVs only virtually eliminates the need for a cam, but can of course be connected.

Diesel decoders can produce over 20 sound effects, including the engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes, fans, brake squeals, coupling and uncoupling, detector sounds, rail clank and many more.

Customize your sounds

Unlike other manufacturers, LokSound Select offers you two options to customize your engine. The most simple is by using one (!) CV. You can select the prime mover sound, the desired whistle or horn and the bell. Each LokSound Select offers various options on that.

However, if you are still unsatisfied with the result, you may at any time use the famous LokSound Programmer to download new sounds into the LokSound Select. We offer numerous “ready-made” sound packages for easy downloading.

Superior motor control

ESU offers load compensation (using B-EMF) since 1999. While other manufacturers seem only to focus on the sound options, the LokSound Select offers the 5th generation of motor control resulting in a smooth and precise locomotive operation. We at ESU believe that good motor control is mandatory for model trains: Even the best sound is worthless if the locomotive running is not smooth!

Regardless if you are using coreless or conventional DC motors, the LokSound Select’s unique auto-detection function can measure the characteristics and adjust the internal settings. There is no need to fiddle around with many CVs to adjust to the engine. Due to Dynamic Drive Control (DDC) you can limit the influence of the load control and operate really smoothly around the depot and over turnouts, while on the main, when going uphill the engine prototypically slows down.

Shining lighting effects

Each LokSound Select include 6 (!) outputs with 0.25A current for H0 Decoders (0.18A for the "Micro Decoders") that can be allocated individually to a light effect, which simulates the light patterns of many popular warning beacons. Besides D312 Rotary beacon, strobe and alternate flashing, there is a firebox flicker, smart flicker, Mars light, Gyralight, Ditch lights (two types), Oscillating Headlights, Stratolight and many more.

The Rule 17 dimmable headlight can be either controlled automatically or by function button. A LED brightness correction feature now also allows using LEDs for lighting effects. This is an important feature since LEDs do behave different than bulbs.

Safeguard

All function outputs and the motor connection are protected against overload and short-circuit. We want you to enjoy your LokSound decoder as long as possible.

Built-in future

LokSound Select decoders are firmware-updatable. This means, the internal decoder software can be replaced by new versions, if necessary. For this, you only need an ESU LokSound Programmer and a PC.
