RailPro Specific Help & Discussion / Re: Deleted files, but still no Free Storage
« Last post by CPRail on January 21, 2026, 02:09:03 PM »
I may be wrong, but I think the Free Storage means the amount of space on the HC, not the LM. Try deleting the files from the HC. The ULT series of sound files eat up a TON of room. My HC regularly shows around 2-3% of Free Storage and I'm constantly having to juggle which files are needed for which loco install.

RailPro Specific Help & Discussion / Deleted files, but still no Free Storage
« Last post by zr1rob on January 21, 2026, 01:32:54 PM »
showing Free Storage at 1%, but deleted many files from several locos. Like "Sanding" which takes several minutes to delete. But still no Free memory to download new files.

Is there something that has to be done to release the memory locked up in those deleted files?  Thanks

Got it all set and working the way I want it. Looks like I was barking up the right tree with my work around, just the wrong branch. ;)

Thanks! Yes, I already have a 1k resistor in place. My knowledge of electronics is limited once you get into resistors and capacitors and what not.

What I have so far is pretty basic: Wipers on the wheels going up to the LED's with a resistor on one side. It should, in theory, work great on a regular ole DC layout. That's not what I've got though, and I do know that.

Thanks for the responses! Now I have a better idea what I need to do.

you can buy the entire full wave bridge in a single small package to save space... it will have the ~ and + and - markings

the cap might help flicker, if it's big enough (mfd capacity)

but remember you need to calculate a current limiting resistor since the LEDs by each run at about 3.6 volts and 20 ma max...

Since you say it works at least in one direction, you may have that done already.

So the full wave bridge in this case is used to provide a continuous output polarity, regardless of track polarity.

Use the "ditchlight" button.  It is programmed to allow function like you are looking for.  When set up correctly, pushing the ditchlight button will turn them on solid, sounding the horn will cause them to flash, they will go back to solid on when done flashing (if that is the file loaded), and will turn off when the ditchlight button is pushed for off.  Button needs to be set to continuous.

Without a sketch or something of how you've wired things up it's hard to say but I'm going to go out on a limb and say from your description your fighting polarity, vis the lights only work when the car is facing one direction but not that other. Not knowing what you've done I'm going to assume what you haven't done. To make the LEDs work regardless of which direction the car is facing along with the LEDs and dropping resistors you'll need a bridge rectifier and a small capacitor would be good too (to help with flickering). It's quite late so I'm not going to look for circuits to show you right now... However even though I said that this is essentially what you need to do:

https://www.coursehero.com/qa/attachment/3974530/

The AC side (the wavy bit on the left side) is the track pickup on your car. The polarity changes changes depending on which way the car is facing. D1 to D4 is the bridge rectifier. Load is your LED's and resistors. C is a capacitor to help smooth things out (will reduce flicker). Depending on how many LED's are in the car you could make the bridge rectifier out of LEDS (they are diodes after all). I could draw that one out later if you wanted but right now it's the day after I stared typing this post and I'm out of here.

I building a lighted caboose (shoving platform, actually) and would like to power the lights off track power. Testing the LED's directly seems to work fine, but when I put them in the car, they only seem to work if the car is facing one direction. Is this a polarity issue or is my set up flawed? It still needs a great deal of refinement as the power going to the LED's is not great or constant, so it could be that, but before I scratch my head too hard, I figured it would be good to know if I'm fighting polarity and not just my janky wiring, you know?

After posting this yesterday, I did some fiddling and configuring and found a work around. Not exactly a perfect solution, but it achieves the end goal.

I have one button programed for Ditch Finish On and programed as a momentary button. Then a second button programed with the regular Ditch light effect, also as monetary, which finished with the lights off. I also have the Auto Ditch Lights on Horn function enabled. Pressing and holding either button flashes the ditch lights, as will the blasting the horn, but the finish on button will end with the lights on solid and full and the other will turn them off.

Like I said, not perfect, but achieves the goal. Any other suggestions?

We were posting at the same time.  ;D  I'll check out your guide and adjust my setup from there. Thanks!!
