Simon Moore Posted April 23, 2019 Share Posted April 23, 2019 I wondered if anyone else has had issues with Hornby super detail hst's not running smoothly? I have 2 I've tried a tts sound decoder & a variety of dcc chips & they all have the same issues. The model will set off then just stop dead then repeat the process. I've tried the decoders in other locos no trouble at all. My layout runs perfectly well with all my other stock but I cannot get these pesky hst units to work. I dont know a great deal about dcc other than changing the decoder address etc. The system I'm using is a nce powered with a dcc concepts 5amp booster unit.

RMweb Gold Corbs Posted April 23, 2019 RMweb Gold Share Posted April 23, 2019 That's interesting, we're having the same issues with a Bachmann 'Warship'. It's not something silly like dirty wheels/pickups? Link to post Share on other sites More sharing options...
hobbyhorse Posted April 23, 2019 Share Posted April 23, 2019 First point is how does it run on DC only. Simon 1 Link to post Share on other sites More sharing options...
Simon Moore Posted April 23, 2019 Author Share Posted April 23, 2019 It runs perfectly well. I have since stripped the bogies & cleaned it all up. I has made them run a little better but still not perfect. Link to post Share on other sites More sharing options...
lennie Posted April 24, 2019 Share Posted April 24, 2019 As you have tried other decoders with the same result, it would suggest to me that the fault is in the unit. How you find it i haven't a clue, except have a probe around the wiring could well be an intermittent break or a dry joint. Good Luck. Link to post Share on other sites More sharing options...
Sir TophamHatt Posted April 25, 2019 Share Posted April 25, 2019 Do you have a video? Interesting as I have had quite a few locos that do this in the past but since changing my layout, I rarely see trains stopping then restarting by themselves. My Hornby HSTs are some of my most reliable. What livery are they? Link to post Share on other sites More sharing options...
RMweb Gold Harlequin Posted April 25, 2019 RMweb Gold Share Posted April 25, 2019 Could it be that the decoder is detecting that the motor is drawing more current than some preset limit and shutting down to protect the motor? That could explain why only that loco and decoder combination has the problem. If so, then maybe there's nothing actually wrong with either the decoder or the loco - you just need to use decoder(s) that have a higher current rating or fix the current draw in the affected loco(s). I don't know if Lais decoders support current limiting but I believe that the higher-end makes do. Link to post Share on other sites More sharing options...
RMweb Premium njee20 Posted April 25, 2019 RMweb Premium Share Posted April 25, 2019 Is the topic title not rather misleading, you’re not having issues with Lais decoders, but with the HSTs...? I’ve never had any issues with Lais decoders FWIW, their crude motor control means I keep them for function use now though. Link to post Share on other sites More sharing options...
