Please check whether CV 49 has an even or an odd value, should be odd. Check also CV 56 whether it is set above zero.

Dave, afaik PP control is not available via Aux on the V4, only on V5. You have to connect to solder pads, see ESU manual for V4 on website. Wolf

Which of the numerous CVs 315 did you change? And why? Do you know how to use the prefix-CVs for all CVs above CV 255? (These are CV31 & 32). Example: If your CV 32 had a value of 0, you just disabled Aux 6. If it had value 1, you just set volume of sound slot 8 to zero.

to be honest I don't know if they replaced outer cylinders or not . . . have to check... but chuff timbre must have been almost identical. EDIT: just checked. They kept the larger cylinders but had cylinder outlet valves smaller than the A4's - so maybe a tie? Really don't know but louder chuffs might suit well...

I think they couldn't because the double blast pipe version also had different gear actuators, clearly visible, even cab interior should be different.

un-rebuilt: 4 rebuilt: 6

Read the data from the decoder with the LokProgrammer. Take a look at the mapping list. Check whether the condition "only when driving" has accidentally been set for F1.

Call or write to locomansounds.com. Best A4 project ever. Can give you advice regarding speakers.

I found different photos of the "British Enterprise" model on the Internet - single chimney and double chimney. Which version is it, please, that Hornby is currently delivering?

There is a rumor that Locomansounds will be launching various W1 projects in January and I fully trust their technical expertise. They did a good research and sound re-engineering with the Thompson A2 and reproduced the sounds very convincingly so I'm wondering how they implement the high-pressure sounds of the W1. This will be a positive surprise for sure.

Have a look at Locomansounds You could also try to contact "ModellbahnUnion" in Kamen maybe they have some Locoman D&H decoders with british sounds

You are right, some sounds can quickly become annoying if you hear them for a long time especially at higher speeds on steam engines. But then you simply have a bad sound project. I have taken out all the sounds that have no longer convinced me and only use decoders that offer the right technology for that.

Hornby mentions additional cab detail, so I am really curious whether Hornby will take into account the changes in the cab for the 1935 version. According to my technical understanding there should be cranks instead of levers for gear adjustment. Also curious whether the position of the lever for the drain cocks will be corrected, in the last photos these were in the half open position, but that's just a small thing.

I think the body shell is made of lh and rh part with the main split line at the top of the boiler. The smaller line could be the mark of an interchangeable tool insert to reflect the differences between 1930's and 1936's version.

Fine. The related sound speed CVs are CV 373 for the sound playback speed at controller speed step 1 and CV 374 for the sound playback speed at the highest controller speed step. Defaults are 128 so as a first try it should be value 112 for CV 373 and value 248 for CV 374. Value 128 means normal playback speed, higher values mean faster. This is the simplest way to try and maybe it is not as expected because the frequencies of the sounds slightly change but should be worth a try. Change in steps of 4 or 8. IMPORTANT NOTE: before you change any of these sound slot config CVs, set CV 31 = 16 and CV 32 = 1, this is mandatory (same procedure as with volume settings). If there is no change, the sound wasn't set up for speed dependent sound.

Limits depend on what the creator of the file built into the sound. But in any case you can try to make the playback speed of the sound dependent on the loco's speed (if the creator has provided this in the file). It is worth a try. To do this, you need to know which sound slot the clack is in. Either the retailer has sent you a document where it is listed, or you have received a CV list for the volume of all sounds. If you can tell me the volume CV of the clack sound, I can tell you the corresponding CVs for the playback speed.

Within limits yes when you have an ESU decoder.

So, why didn't you just follow the link in my above post?

Hi Steve, although the sound can be different, both locomotives should move immediately as soon as the throttle is opened when CV 124 bit 2 is off . If the starting behavior is still different, this can also be caused by the settings of CV2 and CV3.

I think here is the info you need, go to post #7. It is a copy from the ESU manual.

Check CV 124 whether it has the same value in both locomotives. If not, check whether bit 2 (value 4) is switched on. If it is on, the locomotive starts with a delay. If not, it drives off immediately. If you are not familiar with bits, just try to have the same value in both locos. First try the value from one locomotive, then from the other. If this procedure does not help, or if the delay is different, the effect is programmed in the sound sequence and cannot be changed by CVs.

Hi Mike, this is clearly explained in the MS-decoder Zimo manual: Important note regarding acceleration behavior - difference to ZIMO decoders of the MX-series: The acceleration and deceleration behavior according to CVs #3 & #4 refers to the speed steps that are established by the speed table (including interpolation states), both with 3-point and 28-point speed table. This means, an exponential - not linear - speed table also triggers a corresponding acceleration and deceleration behavior. Usually (and also default) such a non-linear speed table is defined. MX-decoders adjust acceleration and deceleration in 255 equidistant speed steps, regardless of the speed table. Therefore the MX-decoders have the special CVs #121 and #122 to change the speed table to an exponential rate, which is not needed with the MS-decoders.

Depends on. Drive-only decoders: Lenz or Zimo. Sound: depending on the layout and type of locomotive: For diesel, I am clearly voting for ESU because it is the very best (only?) decoder when it comes to exactly reproducing all the sound variations of a diesel. See Legomanbiffo's files. For steam if you are just shunting around in the yard, Zimo is not a bad choice. However, if you want to drive on a mainline I'd prefer ESU or D&H, because they are much better in reproducing good sounding chuffs at higher speed especially if you have a 3-cylinder loco..
