Small issue with the above

On DCC SS128, slow running from 003 to 020 loco jerks as it slowly runs, issue clears as the speed is increased.
It's a pre-owned loco and DC running is enabled, wheels clean, track clean etc etc

I will turn DC running off and put it on the rolling road for an hour but apart from that another suggestions before it goes back please.

Thanks

i belive this has come up on Hornby forum, DOG, is well named, for having the odd fault.

What decoder are you using? Some do show these strange speed changes.

Factory fitted TTS

Not much adjustment on those unfortunately.

I think CV 150 is set to 0 as the default, try setting it to 1 as that can help jerky running with TTS decoders.

Thanks all

I searched the Hornby forum on Yelrow's suggestion and found a post that along with CV150 also to change CV154 and CV155. Going for a play now, will let you know.

Glad to be of service.

changed CV150 from 0 to 1 and all is well, didn't bother with 154 /155

thanks very much all

Presume, cheque is in the post.
