Creeping locomotives (was Re: Digitrax DCS100 missing LocoNet packets
'Creeping Locomotives' may be a manifestation of some erroneous wording in early (circa 1997) NMRA DCC standards.toggle quoted messageShow quoted text
IIRC, 'Emergency Stop' was described as 'the first speed step.' When the DCC working group was queried they confirmed their wording was 'correct.' The updated DCC Standards describe emergency stop as an immediate stop.
Since locomotives that had been 'emergency stopped' were actually at the 'first speed step' they often crept. I often coached people to follow any use of emergency stop by then turning the throttle to '0' to make sure the locomotive was stopped.
I don't know if later DCS100 firmware versions ever changed this. Later throttle models actually send a '0' speed command when emergency stop is used.

Speed step 1 means Emergency Stop (i.e. Stop NOW and ignore deceleration settings).
Which dcc system / command station are you using?
