    Boy, they didn't stay looking like that for very long.

    I have received mine. I ordered with sound, however I am not enamored with ESU Loksound for many reasons. In spending quite some time with one and a Lokprogrammer for the ESU decoder, programming them is not for the amateur. First, from Rapido, they do not have the correct horn sound selected for Frisco units; you have to change CV163 to 5 to get a horn that is close. Next, they have the Prime Stratolite programmed as a Rotary Beacon, and attached to F17 to turn it on. To change it to a Prime Stratolite and re-map to a more throttle-friendly F key without the Lokprogrammer or Decoder Pro, I wish you lots of luck. Trying to read and make sense of ESU's manual for the Loksound 5 DCC decoder is like reading an engineering manual for something more complicated than the Space Shuttle. I have spent the better part of an hour trying to compare the manual to what happens on the decoder with the Lokprogrammer and I still don't understand the manual.

    For those who wish to use a SoundTraxx TSU-21PNEM8 decoder or some other manufacturers 21 pin decoder, I have some bad news; the motherboard in the locomotive was designed by Loksound to work completely with only their decoder. Much the same thing happened with the ScaleTrains GP39XL models and it created quite a stink between the NMRA, modelers and Loksound.

    There are some lighting functions that will not work with a SoundTraxx decoder (or other brand of 21 pin decoder) without some type of re-wiring. I have contacted Rapido and will see what their answer is. Since the speaker assembly mounts directly to the motherboard, some modification to the motherboard and re-wiring may be in order.

    Stay tuned for more, as I try to sort it all out. I don't want to use the Loksound decoders just based on general principles; some of the model manufacturers don't fully understand why compatibility with all brands of decoders should be a concern of theirs .

    My DCC system has only 12 function keys. This Locomotive model has 24 functions. A lot of them need to be remapped and some will not or ever be used.
    I have read the accompanying manual and parts of it is comical, eg: They recommend " Or just get a LokProgrammer. No, we will not teach you how to use it":LOL:(n)
    I even read the ESU's manual for the Loksound 5 DCC decoder. Way above my pay grade. I agree with Keith's comments.
    I can change the volume on the sound items, horn selection, bell, with main line programming on my command station.
    Bottom Line: "It Is What It Is"

    Well I'll start off my post with some bad news. I fear the post office delivered my package with 5 U25Bs to the wrong house. I'll find out more tomorrow, but I may have to scramble to find replacements before they're sold out.

    I've posted my disdaine for ESU on here more than once. They're essentially the Apple of the MRR industry. More expensive, gimmick features, incompatible with other products and impossible to work on without proprietary equipment.

    The only thing worse than ESU, is all of the manufacturers that have switched to using their garbage decoders. Each and everyone of them is complicit in this mess.

    Rant over

    Well, fellas, we didn't have that issue 20 years ago. Sounds like a first world problem.

    Rapido was at the National Train Show in Grapevine Texas. I tried talking to them about the U25B. Not the most customer service oriented folks, and I will leave it at that.

    IF I am remembering correctly, I have a good friend that ordered those. Parts were loose in the box when opened and I think one had damaged air tanks.

    Also, as an 11 year Frisco veteran that has been on or around most of the U25B's, he felt the orange was too bright/red-ish for the Frisco's shade.

    Of course, concerns about the color being off is subjective, however parts off in the box, as well as broken parts, is not.

    The above is causing me to seriously rethink my desire for a black and yellow High Hood U25B and a black & yellow low flat nose U25B.


    ESU LokSound:

    I have several Atlas Gold engines that are equipped with ESU's LokSound "Select" decoder of yore. I think they sound great. Now that I've learned to use the "hold drive" in conjunction with their notch up/down feature on the GP7, I have no complaints. I can climb the grade at 10 MPH in run 8, or drift down grade at 25 MPH at idle, as well as settings in between as desired when working level ground. (This applies to the Atlas Gold GP7 only.)

    The Alco's I have (RS-1's and S-2's) all use 539T sounds and are also excellent sounding. Plus, I've learn to set the momentum values so that I can play the throttle steps against the momentum to cause the decoder to really sound nice when switching (rev up/rev down).

    For consisting, I've learned to just mute the GP7 when in consist with my TSU2 equipped EMD's. OR, make the Atlas GP7 w/LokSound Select the lead engine and set the trailing units to idle. That way the prominent sound is coming from the Atlas Gold GP7 and the consist sounds okay when laboring or drifting.

    Lastly, in spite of my rudimentary programming incompetency, I've managed to select the horns I want, and modify values to my satisfaction. If I can do it... you can too.


    Recap:

    The broken/detached parts is a huge off-put in view of my contemplated purchase of a future Rapido black w/yellow stripe U25B HH and low flat nose.

    So much for NMRA standards?
    They all seem to follow the F0= lights F1= bell F2=horns F8=sound, and motor and pick up wire color code?
    Anything after that they can do what they want. They should be held to include how the AUX's on the mother board be for specific Light functions eg: number boards, classification lights, beacons, etc.
    Each decoder company has their own idiosyncrasies on programming. So JMRI was developed to make it somewhat simpler, but when company's go about it their own way, that puts another wrench you have to acquire and educate to make it work.
    Keith's comment on the last paragraph is spot on.

    Another down side to ESU; if you do not have their Lokprogrammer, you have no way of knowing what sound (Horn, Bell, etc) is in which Sound Slot. You are at the mercy of whoever loaded the sounds into the decoder. The ESU Lokprogrammer also has no provision for making a printout of all the settings.

    I captured a screen print of the Sound Slots in the Lokprogrammer:
    Original Rapido U25B Sound Slots.JPG
    and the ESU Function Mapping.
    Original Rapido U25B Function Mapping.JPG

    In Decoder Pro with the ESU decoder, on the Sound Tab, SoundCV Configuration:
    SoundCV9 is actually CV 163,
    SoundCV10 is CV164 Bell,
    S0undCV11 is CV165, Brake Squeal,
    S0undCV12 is CV166, Air Dryer, as listed in the Rapido Manual for the U25B, but don't make any changes without Decoder Pro before reading page 19 in the manual since these are Indexed CVs.

    I got lucky. My order was accidentally sent to my old house in town where it sat out on the front porch all weekend. No one took it and somehow it didn't have any water damage.

    I had about 60 seconds last night to pull one unit out and look at it through the packing sleeve. I don't notice any broken detail parts on this one, we'll see how the other 4 fared. The orange is what I would describe as fresh out of the paint shop bright. I think they nailed the orange-red color first try (hard bar to clear these days). From what I can see through the packing, the details are right on par with what I expected from Rapido. It'll be a while before I can get one on some track to try out, but overall I like what Rapido gave us on this offering, and I hope we get more from them in the future.

    I am in the process of mapping out how to convert the Rapido U25Bs to SoundTraxx decoders both sound and non-sound. So far it is turning our to be fairly easy. I will post all of the particulars here and in the DCC sub-forum.

    I'd say you got lucky there Ethan. You better go buy a lotto ticket.

    I got my one unit about 3 hours ago. Had one loose part I had to glue back on. I have tested it. Now I am pulling down the decoder CV info into Decoder Pro. It does look really good. All the little details. I am going to see if I can get F keys moved to my personal standard next.

    Thanks for putting in the hard work for us Keith.

    Unfortunately Tom, I think I used up all my luck on this one. Better wait a while for it to recharge.

    I have the Decoder Pro Roster File that has been made user-friendly with the original Loksound 5 DCC decoder and has the functions re-mapped so they will work within 12 throttle keys. The problem is there is no way for me to upload the file here so you can import it into your Decoder Pro roster. However, I can email it to your email address that is on file for this forum.

    If you want this Decoder Pro roster file let me know and I will send it to you. It is named Rapido_ESU_5_DCC_Frisco_Corrected.xml

    I will also have a Decoder Pro roster file and the two simple locomotive modifications soon for those of you that want to use the SoundTraxx TSU-21PNEM8 GE #885810 decoder.

    The Whizkid strikes again!

    Thanks for tackling this project for all of us.

    By chance did you change the CV to disable the throttle notch up delay? I plan to disable it in all of my ESU decoders so they play better with others. CV124 to 0 did the trick on some other ESU decoders last fall.

    Found a great layout in the SE Michigan area that runs diesel up to 1980, so this sounds like a job for the Frisco!.

    I bought two Hi Nose U25Bs (800 and 802), but I'm also struggling with the LokSound 5 chip. I usually use JMRI DecoderPro with my NCE PowerCab programming track.

    I can't figure out which LokSound 5 chip I have, as all of the sounds/lights, etc., are defaulted, and I don't know what I'm changing or changing it to. I have pretty much resigned myself to leaving it stock, but I can't operate the beacon on either of my locomotives.

    F17 doesn't seem to work...

    Help?

    Thanks,

    JFM

    I now have completed a Decoder Pro Roster File for the Rapido U25B that supports the SoundTraxx Tsunami 2 TSU-21PNEM GE #885810 Decoder.

    This roster file will set the following function map suitable for use will all DCC systems including Digitrax:
    F0=Headlight (directional), Number Boards, Ground Light, Stratolite, F1=Bell, F2=Horn, F3=Short Horn, F4=RPM-/Engine Shutdown at Idle,
    F5=Dynamics, F6=Brakes (if enabled), F7=RPM+/Engine Start, F8=Straight to Eight & Sanders, F9=Front Class Lights, F11=Brake Select, F12=Cab Light

    To enable Braking Function on F6 , On the Motor Tab change CV 4 Deceleration Rate to 128, and on the Advanced Tab change CV 117 Independent Brake Rate to 116.

    I have set up the speed table to fairly closely copy normal running speeds on the prototype.

    A couple of slight wiring modifications will make the Prime Stratolite and the Engineer's Console lights work. Instructions are attached.


    If you want a copy of this SoundTraxx Decoder Pro roster file, let me know and I will email it to you to import into Decoder Pro. The file is named Rapido_Frisco_U25B_SoundTraxx_TSU_21PNEM8_.xml
