Converting IHS Locomotives from DC to DCC

To make a long story very short, for the last twelve years I have not
been able to engage in model railroading.  Now I am slowly getting
back into the game and I am amazed at how much the hobby has changed.
I have several IHS locomotives I purchased years ago that are standard
DC and I would like to know if it is possible to convert them over to
DCC with sound?

Specifically, I have a 4-6-2 Pacific, a 2-8-0 Consolidated, a 2-6-0
Mogul, and a 4-4-0 American.

How hard and expensive would it be to convert them to DCC?  Is it
something that a relative novice can do?  Or are there services that
will do the conversion for a fee?  Is it worth it or should I just go
ahead and purchase new locomotives already DCC compatible?  Are there
any articles or books that you could recommend to me so I can
understand how to convert them?  Any clues and suggestions would be
appreciated.  Thank you.

Sorry, I mean IHC, International Hobby Corp., not IHS.

If the engines have the cookie cutter flanges, unless they are very
special to you, I would not recommend adding decoders to them. That said
a basic decoder cost about $19. Sound decoders cost more depending on
the quality of the sound.

The instructions that come with most wired decoders is quite good and
the IHCs are fairly easy to convert.

It depends on your electronics ability.  If you've got good electronics
ability, you'll probably be able to convert them with following the
instructions and a little help.  If you're not comfortable rewiring a
locomotive, then I'd suggest having someone convert them for you.

If you decide to do it yourself, make the first purchase a new TCS
decoder.  They have a goof-proof warranty that no one else (of the few
companies I've looked at) has.  If you screw it up, they'll replace it.

On Usenet, no one can hear you laugh.  That's a good thing, though, as
some writers are incorrigible.

The older IHC locos can be done, but it does take some time,
soldering skills, and a lot of patience. The hardest part is dealing
with the headlight wires running down/through the boiler weight.

I highly recommend the TCS M1 decoder for x-6/8-x locos. I've never
done a conversion on an
IHC 4-4-0, so can say what will fit.

THe basic idea of doing a conversion for any loco is to isolate the motor
brushes electrically from the body of the loco and putting the decoder to
those brushes.  The power on the track is 12VAC and goes thrgough the
decoder which converts it into the voltage needed for the speed desired.
All else falls from that.
Needless to say, the track voltage can't get to the motor or you won't have
any control.

One thing that helps with IHC locos is that the plastic frames don't
convey curretnt.
