Wiring of non DCC loco's to DCC

[Wexford]

I have several older locomotives, that are all non DCC.

I would like to rewire them to enable DCC operation.

Really, I suppose, I'm looking for wiring plans for all the older locomotives.

Many thanks in anticipation of some help,

Wesxford.

That very little information to go on.

 

You need to say which models they are, make and model.  They can all need a slightly different approach and some very different.

This may be of some help, but as Rog (RJ) says, a little more information would help. BB

If they are older locomotives, then most likely they will be Hornby X03 or X04 motor chassis (open frame motor).

These previous posts give 'step by step' guidance on how to convert these type of locos to DCC.

Note that older loco motors tend to draw more electrical current than can be supplied by Hornby's basic R8249 DCC decoder. Thus it is important to measure the 'stall' current of the motor BEFORE you contemplate doing the DCC conversion to ensure that a suitable decoder specification is purchased.

If they are Ringfield motors rather than X03 / X04 motors then please advise as there are other sources of info relating to converting 'Ringfields'.

In the model railway world there are very few ‘wiring plans’ published, but in general the pickup wires from the left wheels go directly to one motor brush and the pickup from the right hand wheels go to the other motor brush. Where there is a tender involved any pickups here will be spliced into the loco pickups.

 

The principle of conversion of an early model without a socket to DCC is universal. Isolate the motor brushes from the pickups, then insert the decoder, preferably by way of a socket, so that future decoder swaps is facilitated.

 

As stated previously more info about your range of models will lead to more detailed instructions for conversion to DCC.
