I have held off getting one of these locos until the sound became available. Rails’ Advent discount led me take the plunge.

The sound quality is, IMHO, good. Chuffs synchronise with the wheels and die away when coasting. Control is also very good.

On the other hand, it’s driving me mad! Most of the sounds and features don’t match the function list in the instructions and some features seem to be missing. As far as I have been able to work out so far, these are the actual sounds. I emphasise that I need another session to check the list below.

F1    Sound.
F2    Whistle (single note, playable).
F3    Whistle (random toot or toot toot).
F4    –
F5    –
F6    Safety valves.
F7    Injector.
F8    Brake.
F9    Flange squeal.
F10    Guard’s whistle.
F11    On: guard’s whistle; off: acknowledging toot toot.
F12    Drain cocks.
F13    Fire door (no shovelling, no light).
F14    Shunt mode.
F15    Auto uncoupling.
F16    Coasting?
F17    –
F18    Rattling?
F19    Flange squeal.
F20    –
F21    –
F22    –
F23    –
F24    –

This is driving me potty too. I took delivery of my pre-ordered-from-Hattons N7 with sound in October but it has been locked away till Christmas!

 

It runs well but then the problems start. The sound is very quiet. I have many other Loksound- and TTS-fitted locos and they drown this one out. I have looked at CV63 (Master volume) and that is set at the max, 128. I went to look at the individual volumes but accessing those via Railmaster and e-Link, all I get is "not used" for all of those. I have noted in the instruction leaflet that CV31 should be set to 16 and CV32 to 1 (it was set to zero), but, having checked and corrected that, I still can't access the individual sound volumes (CVs of which range from 259 to 467).

 

Most of the F key assignments are not as per the instruction leaflet, as ´No Decorum´said in his post, above. Some are so quiet, it's impossible to hear what they are supposed to be. I found AWS bell at F19 but no sign of AWS siren. Flange Squeal I concur at F9 and F11 for Guards whistle. I'm still checking the others.

 

It's a nice model but, having paid for sound, I expect to be able to hear it and to access the functions from a list that is correct. I will contact Oxford Rail as soon as the holidays are over but would welcome any ideas about the low level sound issue. Thanks.

Also I notice F16 in the above list says "master volume".  I wonder if playing with that may help the volume issue mentioned above.

Thank you Dominion. I'll see if the rest of mine match this list! The ones I identified certainly do. So no AWS siren!? On the list that was included, AWS siren is there which also slows the loco. I have found no sign of that.

 

I'll try these out tomorrow. Thanks again.  

 

PS Was there an indication on your list which of these sounds were "latching"?

I had some fun with my N7 yesterday. (sound fitted)

ESU has a function called "Automatic Calibration of the Motor".

I prefer the name Rapido gives it, they call it "Awesome slow speed thingy". 

If you haven't tried it before it is worth a go.

When I first did this last year it put the steam chuffs out of sync so I reset the motor control to the factory settings, but now I was able to do both steps.

 

Set CV54 to 0. Make sure the loco has 4 or 5 feet of open track ahead of it, preferably flat and straight. Press the bell function. The loco will take off at high speed forwards for about 2 seconds. During that step you have no control over the loco so make sure the track is open with no risk of disaster.

When the loco stops the ESU chip will have monitored the motor and back-emf behavior and automatically tuned the motor and BEMF settings. It worked really well on my N7. It runs extremely  smoothly, even better than before, and also very nicely at very low speed.

 

The process upsets the factory steam chuff calibration but that wasn't quite right at the presets on mine anyway. Following the Loksound V5 manual, by trial and error I increased CV 57 to get the cuffs synced on speed step 1 (I used 128 speed steps for this though I did not find that explicitly in the ESU instructions). I settled on 240 as the best sync for my loco and BEMF settings.

Then I set the speed to 4 (from 128) and increased CV58 till the chuffs were synced there too. (settling on 80 for mine)

It was the first time I have altered the chuff settings on a loco and it worked fairly easily.

(CV8=8 goes back to factory presets on all if necessary)

Thank you for posting that; very helpful. Oxford isn’t very co-operative. Most functions now seem to work although I’m not getting a glimmer from the firebox.

I've had my BR black one for over a year now, & the fact that the smokebox door numbers were printed on always bugged me. Decided to fix that this weekend; just a piece of plastic from an old kit cut to size, sanded & painted black, and some transfers from Modelmaster. Stuck down with some uhu & a little bit of fiddling to get straight, but looks a lot better imho.

At the price these are going at I couldn't resist getting one of the sound fitted examples. It’s almost like getting a free loco with every sound decoder. 
 

really pleased with it. 
 

Edit: the source I got mine from, Rails, have sold out.

Sooo, anyone any idea whats going on with the BR late version?

Cheltenham Model Centre seems to have them but nowhere else does. Not even seen any of the big retailers even say they got them in and sold out or anything.

I bought one from Monk Bar Models in York back in early December (not DCC / sound).

Transport delays and shortages of stock so I'm led to believe.

ORN70004 can however be purchased direct on the Oxford Rail website.

If you're still trying to source one, try Derails of Coleford which has them on pre-order for £84.70.
