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..

Facts: 1. The multiplier is not an NMRA standard, just a recommendation. 2. Is it really that "tricky" to only multiply two (!) Values by 3.6 to get the same results? Don't believe. 3. The real problem is with most of the Zimo decoders, because the acceleration / deceleration curve (not the speed curve) differs from all other manufacturers. Zimo sorted that with the latest MS decoder series, but other Zimo decoders still have this Zimo-specific curve incompatible with other brands.

Sometimes I feel ripped off on this forum.

Let's calculate: (on the safe side) U booster = 20 V R = 50 ohms (example) U / R = I = 20/50 = 0.4 amps P = U x I = 20 x 0.4 = 8 watts short-term possible resistor overload factor: 5 to 8 8 watts / 5 = 1.6 watts ===>> resistor 47 ohms / 2 watts Just as a try (do not try to operate your layout with that): install a fat resistor between booster and layout, (let it hang in free air or rest on a surface that can neither melt nor burn) switch on the booster see if the booster goes off or not (if the resistor becomes hot, switch off) When you found a suitable Resistor: Take a push button switch that is normally closed. Connect it in parallel with the resistor. (The switch must be able to withstand the entire booster current at all times.) Press the switch button, turn on the booster, release the switch button (somehow that reminds me of starting a very old truck).

Modern boosters have 2 types of protection: 1. If the current exceeds the nominal value, it switches off (overload protection). 2. If the current suddenly increases within a very short time, it also switches off (short-circuit protection, called dI / dt switch-off). This happens even if the current does not reach the maximum value! Variant 2 is always important when a short occurs at a distant point in the layout and the resistances in the wiring and / or in the track (insufficient track bus) are so high that the rated current is not exceeded because a current of 4.9 A can sometimes make the loco pickups unusable. Unfortunately, at the very first moment of power-up, capacitors cause something similar to a short with current only limited by the resistances in the layout, wiring and decoders. One solution is to have the capacitors charged in groups one after the other, as has been suggested. Or you can use a soft start device. In the simplest case, this is a resistor between booster and layout that is bridged shortly after the booster is switched on.
