mbinsewiThe cost makes me run away.
what if you could build your own, similar to TAT-V? would the features of the ProtoThrottle be that enticing to be worth the effort?
there are inexpensive systems on chip (e.g. esp32) that can easily be programmed with just a USB cable that also support WiFi. a few extra components: oled display, levers (?), switches and buttons. firmware could be downloaded from the web.
if not, what are the ProtoThrottle shortcomings?

Doughless Bayfield Transfer Railway My primary interest is operations, and they add an incredible amount to the experience. As a pleasant bonus, they make road trains take longer in their run, which helps keep the yard from getting buried. I'm curious, does it do anything that a normal throttle can't do, if a person knows how to operate a normal throttle and set up some basic CVs into the loco? What I see is a horn lever that looks like the real tooter, and a notching lever that looks like the real notcher, and their placements relative to each other being accurate. I'm just wondering what the throttle does that is actually different/easier than a normal throttle.

You have to look at it from the other direction: how do you get a realistic-looking locomotive throttle control to function with everything that a DDC throttle can do? What you're paying for as a result are the electronics to make those levers and buttons interface to "normal" DCC controls. In addition, the machined, silk-screened and anodized metal casework, high-quality knobs and levers, are at least 50% of the cost, I'd estimate - maybe more.
I'd like to have one, just as a working monument in a layout room. As for using it all the time, no - I'm with Richhotrain on that one.
Still, one should recognize that it's a major achievement as an add-on product for model railroading. I'm certain that those that want it and can afford it are purchasing them. Maybe they'll come out with a more affordable mini-proto throttle eventually.
richhotrainPretty cool, I guess, if you are really into playing engineer with the time and patience to continually operate the throttle. This guy spends a whole lot of time with his fingers pressing buttons and moving levers.
Same here. The cost makes me run away.

I have one and absolutely love it. it is like a lot of MR electronics, once you use it, it is hard to go back. It was worth every penny.
wrench567Looks cool. But I'm a steam guy. They have a Johnson bar version? ;)
I argued for many years that one of the nonprototypical things about model steam is the fixed toylike representation of valve gear on supposedly operating steam locomotives. Even a solenoid that jerked the block from one end of the link to the other when reversing would be better than nothing; a good model would use a proportional drive to position the cutoff and then use that along with BEMF and other factors to determine the 'chuff characteristics'... and the power the engine 'produces' to accelerate and move a consist. Apparently we now have at least one system (described here a few months ago) that actually does this.
It would be nominally simple to provide 'one more lever' on the device pictured that would control simulated cutoff. It might also be possible to use a rotary encoder or screw pot to simulate the action of a wheel reverser, with an appropriate display (perhaps a needle on a scale or a segmented LCD meter) that would show the amount of forward or reverse cutoff, and perhaps a digital % that would allow setting the fixed cutoff and contribution of starting or slot ports, or Herdner valves, as part of configuration.
If anyone wants a discussion of what steam valve gear does, start one over on the Prototype forum.
I had a chance to use one of those throttles a couple of years ago. If I could afford it, I'd get ten of them.My primary interest is operations, and they add an incredible amount to the experience.

wrench567There's no way to shut off chuffs. As long as the wheels are turning the pistons and valve gear are still engaged. There will be noise associated with that movement.
There is the "Drive Hold" function of the ESU decoders which can give the operator a little more control over sound intensity vs. speed or power output. This effectively allows you to select weather the encoder or throttle input is affecting the motor output OR the sound output. I like to play with it especially on diesels where I can mimic starting a heavy train and have the engines working very hard but the speed of the train at a crawl.
Other decoders will increase sound intensity by sensing the BEMF of the motor (or by current draw) and, generally, they will have a feature to manually increase or decrease the "load" weather it be a diesel engine sound or cylinder exhaust sound.

There's no way to shut off chuffs. As long as the wheels are turning the pistons and valve gear are still engaged. There will be noise associated with that movement. There will be the sounds of air transfer through the valves and cylinders. But there is no sound of power (boom) and the volume of sound is decreased to almost zero. Like trying to start a lawnmower engine with the spark plug removed.
Hope this answers your question.
Pete.

It's all in the decoder setup. Deceleration momentum is huge. On my heavy steam (2-8-0) and above the deceleration momentum is set anywhere from sixty and more. I also remap the brake function to button 3 because my Lenz LH90 has few function buttons.
There are almost unlimited settings on modern decoders.
wrench567The Loksound and especially the WOW sound decoder are almost silent while drifting.
in the demo i've seen, ESU Steam Project, the chuff volume decreases presumably when the speed is decreased.
what i'd like is a function that can supress chuffs completely to mimic an operator closing the throttle and drifting
imagine an engine under power with chuffs, the throttle closed when slowing, preparing to stop or going downhill without losing much speed and finally brakes being applied and the train slowing rapidly and the possibility of opening the throttle to drag a train to a platform without releasing brakes
gmpullman gregc but i believe there's a 2nd part ... that affects performance i don't think being in 1st gear at speed achieves max power. i believe there's a similar thing with steam engines You lost me with this statement.

You lost me with this statement.
why does horsepower (i.e. force) drop beyond it's max as rpm increases? so you find a gear where the rpm is closer to max HP of the engine
not sure if it's loss of effiicency due to things like valve float or because there's not enough time to get enough fuel mixture into the cylinder.
a reverser isn't like a gear box, but it does control the flow rate of steam which has two effects

gregc wrench567 The latest sound decoders considering that closing the throttle doesn't bring the train to stop, brakes do, i think it would be interesting if sound decoders could mimic the mechanical sounds of a train coasting with little if any throttle
wrench567 The latest sound decoders

The Loksound and especially the WOW sound decoder are almost silent while drifting. I don't like the rod clank sounds so that is either volume cut or not enabled. Sometimes all you can hear is the turbo generator or water injector. My Loksound Select decoder makes what can be described as a piston sucking sound while being pushed down hill by the train. Being a Select instead of a more expensive decoder, I can't seem to get rid of that sound. To be honest I haven't really tried. Most of my steamers have a power reverse. Mostly lever action but a few screw reverse.
The PRR built the I1s 2-10-0 using a fifty percent cutoff. Economy was the goal. Later upgraded to 65 percent cutoff. That made them I1sa. They were powerful beasts that lead the railroad through the drag freight era. On YouTube there is a sound cut of one trying to start a heavy train. The wheel slip is a sound you won't soon forget. You can hear the engineer bunch up the train several times. It gives it a little boost from the draft gear springs as the brakes are released. Well worth the search.

Good Luck, Ed
gmpullmanIf an engineer did that he'd run out of coal and water before the end of the run, not to mention exhausting the fireman. I'm sure you're familiar with the term "cutoff". Would you drive your car in first gear with all cylinders working at maximum power output 100% of the time?
thanks for answering the question.

Some do. When "drifting" the sound of side rod clank is increased and a hint of a "snifter" which is a type of vacuum breaker some engines used. Not all engines had sloppy side rods, depending on when they were last shopped and new brasses installed (or have roller bearings). Tramming and/or setting of the driving box wedges also affects how much "noise" a drifting steam locomotive makes.
gregcwouldn't you want the cylinders to always "work their hardest"?

wrench567 ATLANTIC CENTRAL gregc wrench567 change the admittance of steam going to the cylinders how do you think that impacts performance? With or without a power reverse, the Johnson bar changes the valve cutoff allowing the cylinders to work their hardest, or work "lightly" or coast in "neutral". Past neutral is reverse.... Someone else can consider the idea of how that is simulated with an electric motor and a DCC throttle. Sheldon Sheldon. The latest sound decoders I have (TCS WOW and Loksound) have an algorithm in the software that uses BEMF tied into chuff intensity. Chuffs are more intense while starting a heavy train or climbing a grade and almost goes silent downgrade and coasting. Something that the old decoders didn't do too well. $500 for a throttle is rather steep. On top of needing a DCC system also. Perhaps if the price was around what an extra throttle would cost, then maybe a consideration. Pete.

Well Pete, I know what a steam locomotive sounds like working hard and coasting.
BUT, I don't have or use DCC and I don't have any interest in onboard sound in HO scale.
I still run DC, with Advanced Cab Control, and wireless radio throttles.
But this whole idea of trying to simulate every action that a real engineer has to do to run a train is of ZERO interest to me.
One of my other hobbies is designing and building HiFi speaker systems - onboard sound reminds me of trying to listen to music on a 1968 9 transistor radio with a 2" speaker. I will pass.
You are complaining about the cost of this thing? How many DCC sound equiped locos do you own? How big is your layout?
One could make the argument that current $600 locomotive prices are "steep".....
I only replied to this because obvious questions seemed unanswered or not correctly/fully answered.

Some of this stuff is fun, some of it he's going deliberately slow to display the throttle. Personally, I like his layout and how he operates it, and his videos.
The early parts of the video where you see his train move is pretty much how I run my layout. Even the mainline running across 18 feet doesn't go any faster than that. Its why I'm so phinnicky about slow speed movement of the trains. Heck, they all run great when they go faster than 20 mph, LOL.
Most of that running and the sounds can be done with proper CV programming and a normal throttle, IMO.
I think most of the fun for some is simply how the throttle looks.
All of this amounts to a lot of minutia for some. I like most of it, but some of it seem tedious. But its no more minutia to me than another trying to notice the cab contour of an F unit, or the rib detail of the end of a boxcar, or underneath brake rigging, or making up the "correct" train schedules to model how their prototype ran in 1965. As you said, something for everybody.
MR contributor Thomas Klimoski uses the throttle on his layout. He has a website with lots of videos that explain the reasons for the movements and idle time. He builds his switch list, and simulates the movements of the two man crew, so its not just playing engineer. Not that you place figurines around the train, but it shows how much prep work the crew has to perform to switch a few cars. All can be sped up with a crew movement fast clock, like some do with their train schedules.
