Factory fitted DCC chips

My son has just got one of the Hornby factory fitted Jinty 0-6-0's and
it runs very well .... but it's a bit slow ! Is this usual for
factory fitted loco's ?

Also, cant find a service sheet for the 'new' DCC model ?

Depends what you mean by bit slow, its supposed to be a shunter. Probably
hasnt changed that much to justify a new sheet.

a) Speed on model railways is difficult to estimate. Most people run
their trains much too fast, as true scale speed looks slow. 60 scale mph
(100km/h) is about 10 inches per second (25cm/sec) in OO. That looks
slow, because normally you're looking at the train from 300 scale feet
or more - the length of a football pitch. Quite a distance. DCC fitted
locos are usually programmed to provide a realistic top speed (which for
a Jinty would be around 40-45 mph, right? That's about 6"/sec, 15cm/sec.

b) You can reprogram the engine so that its speed range is more to your
liking.

c) What you need is a spec sheet and programming instructions for
Hornby's version of DCC. This information AFAIK is included with
Hornby's DCC controller.

d) Hornby is following NMRA standards. The chip contains "control
variables", or CVs, which are user-changeable. Hornby lists them on its
web site. If you need to know more, try nmra.org, and consider buying a
beginner's book on DCC. You need to change the vales in CV 2 through 7
to change the Jinty's speed.

e) Follow Hornby's programming instructions (they come with their
controllers.) If you are using a 3rd party controller, use its
programming facility as instructed. All NMRA compliant decoders can be
programmed; certain CVs are included in all decoders (eg, 1, which holds
the locomotive's address -- this is set to 3 by default, and must be
changed if you intend to run two or more DCC locos at the same time -
which is, after all, the aim of the game.)

Thanks for your thoughts folks !

I remember the current proprieter of ZTC telling me that the original RP
for the default address in decoders should be the manufacturer id which
for Lenz was 3 and some other manufacturers copied that default and it
became the defacto standard.

I thought Lenz's ID was '99', Bachmann 101 and so on. It makes it very
difficult to use that ID as the default address as some systems still use
2-digit addressing.
