Is it the specific Lokpilot  for the A Class? If not then the headlights probably just need to be mapped to a function key. 

No its just a standard decoder.

What DCC system are you using? Can you program CV’s with it?

I'm not sure. It's an NCE Power cab.

*No , there is no specific A Class Lokpilot non sound decoder available from IRM or elsewhere as they have already stated until 2022 .

*ESU have stated that there is a world wide shortage of non sound decoders and will not be available until 2022.

 

If not then the headlights probably just need to be mapped to a function key.

*The headlights operate from F22 via Aux3 & Aux4 .
you will have to remap Aux3 & Aux4 as irishthump has suggested.

They seem to yes. Once I have the current CV value of the headlights I should be able to change it following instruction I found online. 

OK give this a go. Change the following CVs in this exact order. This should give you directional headlights on F7.

CV31 = 16, CV32 = 3
----------------------
CV385 =   4

CV31 = 16, CV32 = 8
----------------------
CV385 =  16

CV31 = 16, CV32 = 3
----------------------
CV401 =   8
CV403 =   4

CV31 = 16, CV32 = 8
----------------------
CV401 =  32

CV31 = 16, CV32 = 3
----------------------
CV419 =  16

CV31 = 16, CV32 = 8
----------------------
CV417 = 128
CV418 =   0

CV31 = 16, CV32 = 3
----------------------
CV435 =  64
CV436 =   0

CV31 = 16, CV32 = 8
----------------------
CV434 =   1

CV31 = 16, CV32 = 3
----------------------
CV452 =   1

CV31 = 16, CV32 = 8
----------------------
CV450 =   2

CV31 = 16, CV32 = 3
----------------------
CV468 =   4

CV31 = 16, CV32 = 8
----------------------
CV466 =   4

CV31 = 16, CV32 = 3
----------------------
CV484 =  16

CV31 = 16, CV32 = 8
----------------------
CV482 =   8

CV31 = 16, CV32 = 3
----------------------
CV500 =  64
CV501 =   0

CV31 = 16, CV32 = 8
----------------------
CV498 =  16

CV31 = 16, CV32 = 4
----------------------
CV261 =   1

CV31 = 16, CV32 = 9
----------------------
CV258 =  32
 

If this does'nt work just program CV8 with a value of 8. That will reset the decoder back to the original settings.

Thanks. I will give that a go.

If it helps, this is the function list on the A Class LokPilot chips. 

Screenshot 2021-10-28 at 13.28.30.png

For me it's:

F0 Directional white marker lights 

F1 Red marker lights (fan end) 

F2 Red marker lights (other end) 

F3 Shunt mode

F4 Nothing

F5 Nothing

F6 Nothing

F7 Both cab lights

F8 Shunt lights (fan end) 

F9 Shunt lights (other end)

Did you try the CV changes I gave you yet?

Are these "A"s any more prone to this than other models?

 

I could'nt imagine how they would be. The fact they are so heavy would make me think they would'nt have any issues.

I'm going to have to tear all of the track up and start again. The amount of derailments are doing my head in. 

 

 

 

Curious as to the cause of this myself! Is it the locos that derail or the stock? Or both? 

Are you using code 75 track?

The As derail no more than other stock. The main problem items the joins in baseboards. The track flattens out a bit and also lowers as I had to make the bed solid at the joins in order for it to not move and mess up track alignment. 

The other issue is that I have points right next to the baseboard joins. So when the derailing happens it's usually because one wheel set is hovering above the rails as the other wheels are sitting on track that it's slightly higher in level. This results in the free wheel set derailing and causing a short. The MM 071s are the worst culprit for this.

As can be seen in the photo below the level difference is very slight but the problems it causes means I can't run trains...

Yep that sounds like a problem alright! part of the issue is the finer flanges on more modern models are less tolerant of uneven track. With the old Lima and Hornby "pizza cutter" wheel flanges that sort of thing really didn't matter. The long wheelbase of the 071 won't help matters either.
