DCC - effect on old Farish loco's

My first posting but I'm sure you guys can help me.

I'm starting a layout after many years absence and reading through this forum and the usual publications it seems obvious to go down the DCC route for a new layout However I have a number of old Poole built Farish loco's that I would like to convert to DCC but I'm not sure what effect DCC will have on these as they were built to either be running or left in an isolated section. They were not built to sit idle in a powered section of track, is it likely to burn out the motor and should I plan to add some isolated sections or do the decoders help protect the motor? Finally I only intend to use two function wired decoders on the loco's (can't see any reason for more functions as I don't plan to use sound), are there any types I should avoid installing on Farish kit.

I too am using DigiTrax DZ123 / DZ125
These are a good compromise between size and functionality

As above, there are no issues with burning out of motors whilst they are sat on "live track"
However, make sure that the power settings are returned to zero when the loco comes to a stop (and not a very low speed setting that results in no movement, such as 1 or 2)

I have had one 3 pole motor converted and as this model is just as good as any other 5 pole motor
However, it was very good under DC, it was more of an experiment to see if it was possible
Equally, I have some 5 pole motors that perform poorly in comparison
The trick is to replace worn parts whilst stripping the models down as part of the conversion
Therefore buy some replacement brushes, refit them irrespective

Ironically, some of these older models run better than some of the latest (BachFar) DCC ready versions, which annoys me greatly
