Neil - I wouldn't worry about synchronizing the sound between front and rear of an HST. (SWD announced the HST about a fortnight ago). When I am waiting for an HST to pass at the local crossing, each motor car sounds as an individual. The sound of an HST does seem to be quite distinctive as the engine spins up when the driver sees the green for the line ahead.

Syncronisation would be an issue with the HST. The HST power controller has five notches, all apart from notch one result in an engine speed increase. The power cars rev up simultaneously because when the Driver notches up in the front power car, an electrical signal is sent to the rear power car to select the same notch. There may be a very slight delay due to mechanical differences, but it shouldn't be much.

It does get complicated when you factor in the power car that is producing the train supply (usually the rear one). This power car will not be idling like the other one, it will be at notch two level revs at idle, because of the electical load on it. It would be interesting to see if you can program the chip to do this.

Cheers,

Peter.

With DCC both power cars would receive the throttle instruction either at the same time or within a few milliseconds which ought to be adequate synchronization.
If SWD know about it, it should not be a problem to be able to program a decoder as representing the train supply provider and adjust the idle level accordingly. Perhaps Peter, you could send tham an email asking if they will support this effect.

Well I managed to pick up a 66 from Tower Models on the friday afternoon at warley it runs very well and sounds gerat, I paid £120, good job I did get it on the friday as there was not one left in the whole show with in 1 hour of the show opening on the saturday morning.

Hi just a word as I'm on my way to the railway club I picked up a 66 with sound at Warley on
Saturday I've only just started to run it in but I'll pass on what it's like later I paid £125 for it

I thought the one at the show had a fantastic sound. Interesting to note the observations about cut out mesh roof grills to improve sound. One of my club colleagues wanted to do a body swap with me as he wants the body for his collection but not the sound chassis. I'l have to mention this to him on Tuesday. He may not be too happy!

This could affect all future potential body swaps if sound locos have special acoustic bodies.

Happy modelling

For the purposes of my HST I may just install one sound decoder and have a connection to another speaker in the rear car. It will be a hassle threading wires through six or seven coaches but it's that or another hundred quid.

I'm looking forward to getting it back into action.

>It will be a hassle threading wires through six or seven coaches
What kind of couplings are on the coaches? If it's NEM pockets, you could switch to conducting Rocos.

The couplings are the big ugly Hornby standard ones. What are these conducting Roco ones? This sounds like the solution to another problem I have.

 

[william]

I'm back from the railway club anyway on the idea of swopping body's between sound and none
sound 66's when I picked up my sound fitted 66 I got a new DRS 66 this was none sound fitted
but had the same body with the cut out grill where the speaker would go and the new on/off switch
for the rear red lights so swopping new bodys would not be a problem !!!! I think

Sorry to but in ;

Roco make (or used to - there were patent issues regarding the 4-pole conductive/NEM coupling, the Roco close coupler & the roadbed for the Rocoline track during recent events - I will try & get some more in the next Roco order) a 4-pole conductive coupling, good product except that it was a pain to manually couple up a rake of more than say 3-vehicles.

Another solution would be to use the Roco close coupling conversions which give you NEM pockets & use the Veissmann 2-pole conductive couplers which are based on & interchangeable with the Fleischmann Profi Coupling.

any advise or opinion on this subject would be really good so please go ahead

You don't have item numbers by any chance do you?

I'll look them up & post the results later (hopefully) today.

I'm really going to buy a Class 66 with sound! Probably January or February when I've got some more money.

But that Class 20 sound good too.

(I'll want to buy them all.

) And I want to know how the HST sounds.

Hi Neil (& anyone else interested),

The Roco coupling conversions are :

40343 for vehicles up to 170mm long.
40344 for vehicles over 170mm long.

I don't think that the 4-pole conductive coupling is available any more from Roco.

There is an alternative that we are looking into.

Anyone interested please send me a private message.
