Hi Billy,

Reading through your list I like what I see described, I imagine the
logic to do it all might see a couple of very raised eyebrows from
Tim Ring though. Some of what you describe I can do with the torque
couplings I have so the settings would at least need to be adjustable.

On the brake, I think if this can be a part of what you load onto the
LM2 instead of the HC-2 we can go further than generic as well and
replicate the major difference in braking, being self lapping and the
other one where you had to apply the brake handle to reduce pipe
pressure and then move the brake handle to off to stop dumping air.
This might be going too much on the advanced side of course.

I think it's a great idea for this community here to come up with
ideas that we can submit as a community, we might get things higher
up the ladder if he knows it's coming from a community of users instead
of just a single user.

Cheers,

Tim

Bill -

I agree with most of your suggested improvements.  Longer accel/deccel is definitely needed for more realistic operating.  The addition of a coast and brake function would also be enjoyable.  However, I've currently been doing this "manually" with just manual notching.  I can play the prime mover to sound like what I want while controlling the speed of the locomotive to match the movement I am looking for. 

The biggest positive that could come from using coast/brake would be smooth spooling of the prime mover.  But here's the kicker: how do you get the prime mover sound to run smoothly from one notch to any other notch?  Do you need to have recordings of the engine spooling up and down through multiple notches?  Or can it be done with the existing recordings of individual notch transitions and somehow "blend" them together?  I have no idea how other manufacturers have done theirs.  I imagine this could get rather complicated/difficult.

Things like the brake button could be similar to the diesel prime mover button, in that it isn't just a button.....it actually has some code behind it.  For example, the diesel prime mover button has code written into it that allows the prime mover file to be played correctly.  Try loading a steam engine sound and playing it through the diesel prime mover button....it doesn't work right, I've tried.  The brake button could have parameters that could be adjusted, such as rate of braking, and choosing the sound to play (or not play, which is what I would want), volume, and momentary or continuous as with any other function button.  Seems like it would be pretty straightforward.

I do really like the notch indicator.  That should absolutely be added.  Also the combined manual and automatic notching is golden.

One more thing I'd like to add:

    Dynamic braking across consists - tap the button on the lead and turn on the dynamic brake button on all locomotives.  I'm fine with just the sound, but could possibly be turned into an actual function button.  Easier though just to control the locomotives by hand.

I have added Kevin's Dynamic Braking item to the list.
I have also reconsidered the rest of the list and conclude/agree, some of these items are redundant given the Combined Auto & Manual notching item.

So here is the revised proposal - more discussion welcome.

Allow for heavy momentum settings
 - Allow for Accel and Decel times of up to 120 seconds

Allow setting of throttle percentage where notch 8 is reached
 - Let users set the percentage of power above which the sound is always notch 8.
 - ie: this is the average full power setting on the layout.

Intelligent Throttle Response (Ballistics)
removed – not needed given Combined Auto & Manual Notching

Coast Feature  (toggle)
removed – not needed given Combined Auto & Manual Notching

Brake Feature (toggle)
 - Play squeal sound until button is released
 - When stop is reached, automatically deactivate this button
 - Spool sound down to idle (notch 1)
 - Decelerate train until button is released or stop is reached
removed spool down and decel points - not needed given Combined Auto & Manual Notching, in some cases you wouldn’t want notch 1 even though the brakes are squealing.

Combined Auto & Manual Notching
 - Allow the user to increase or decrease the notch level at any time
 - Override the manual choice when the throttle is changed.
ie: the locomotive is moving at 40% power (auto notch is at notch 4) and the user manually increases to notch 6, then:
 - if the user decreases the throttle to 30% auto-notching brings the sound down to notch 3 and manual notching is cancelled.
 - if the user increased the throttle to 50% or 60%, notching does not change.
 - if the user increased the throttle to 70%, auto notching increases to notch 7 and manual notching is cancelled.

Notch Indicator
 - Display the current notch level on the display.

Improved Revving (smooth)
 - The notches do not notch up/down smoothly.  In manual notching you can outrun the sounds and skip over and entire sound causing the LM-2 to sound bad.
 - Tim says: We did not know this problem existed.  We plan to fix this in a newer revision

Dynamic braking across consists - tap the button on the lead and turn on the dynamic brake button on all locomotives.  I'm fine with just the sound, but could possibly be turned into an actual function button.  Easier though just to control the locomotives by hand.

Hi Bill,
I like your revised list. Not being a user(yet), I should think that the opinions of those of you who are, should carry the most weight.
I'm modeling the steam era so the dynamic brake won't do anything for me but I like the idea nonetheless!

Speaking of which; is there a provision for adding an axle or wheel contact to synch the chuff? The demo video I've seen is good enough for me but I figure if we're asking for other goodies, why not throw another one in the mix?! :)

Shawn,

I've talked to Ring about the cam chuff synchronization in the past.  It can be done with the LM-2S because of its dual inputs.  However, with Railpro it shouldn't need to be.  You can fine tune the chuff rate on the locomotive while it's moving until the chuff hits exactly where you want it to be.  From there the chuff should be synchronized at all speeds.  Much easier than adding a cam.

That's one of the nice things about Railpro that is impossible with DCC.  You can make adjustments to the locomotive in real time as it's moving down the track.  That way you can see instantly what effect your adjustment had on the locomotive.  No more programming track, flipping it back and forth between "program" and "run", reading CV's and rewriting their value on JMRI, or any other nonsense. 

Now, I don't have any steamers myself so I haven't actually tested adjusting the chuff to synch with the drivers on a steamer.  I have however loaded the steam files onto a diesel and tested out all the functionality, including adjusting the chuff rate in real time, and it does work.  Perhaps someone with a steamer can confirm?  It should work just fine.

The few videos floating around on Youtube of Railpro steamers are unsynchronized BTW.  I'd like to see some good videos of one that has been synched so that everyone knows what can be done.
