GAUGE: 00, Train Doctor,

Update November 2021:

Please note we are unable to supply Gaugemaster decoders at this time and will be fitting Hornby instead. This also means we cannot fit a stay-alive capacitor.


We can now offer DCC decoder fitting to your locomotives!

This option is for us to fit a DCC decoder into your own locomotive.

When you book this service our system will send you a form to complete and send back with your loco's. Please check your spam/junk folders if it hasn't come through within a few minutes. Alternatively please click here to download your copy.

Once we have received your order our system will automatically send you a form to complete, then you simply send us your locomotive and we do the rest! No need to work out if your loco is DCC Ready or not or which type of decoder you need, we'll do all that (unless you have a preference then we will fit that one!)

Remember most 2 car DMU's will require 2 decoders, so you will need to add two DCC fitting services to your basket.

When your locomotive is received we will fully inspect and test your it before carefully fitting the right decoder. Then we will test again before re-packaging and returning the locomotive to you with a full copy of the report.

We use the best Gaugemaster DCC decoders.

Our price includes the decoder and return postage to you. The only extra thing you will have to pay is the postage to deliver the locomotive to us.

Would you like to add a Gaugemaster Ruby PowerPal capacitor as well? Click here to add one to your basket and we will fit that at the same time!

We include all the original manuals and packaging from the DCC decoder.

Fancy adding some smoke?

We can now fit Seuthe smoke generators but this is dependent on the amount of space inside the loco. Usually the cost for fitting is around £20-30 plus the cost of the smoke generator and can only be done at the same time as the decoder fitting. Please call to discuss the options with us. We usually need to see the loco first to assess the feasibility and will invoice you after the work is completed. 

Please note we cannot retro-fit smoke generators to locos with DCC decoders already fitted.

Not sure what you need? simply give us a call or send us an email and our technicians will be happy to help!

Please note:

We are unable to fit DCC decoders to every single type of loco on the market since some are incompatible by design (usually older ones made long before DCC was invented) Here is a list of some of the loco's we are unable to convert to DCC:

  • Bachmann split-chassis type (notably Hall class)
  • Most Triang locos
  • Some early Airfix locos
  • Mainline steam engines
  • Very early (1960's) Hornby steam loco's (notable 8F)

We can convert silver seal ringfield motors (Hornby Britannia class and others) but there will be an additional charge as the motor contacts need to be drilled out.

Please give us a call if you are unsure and we will be able to advise you.

If your locomotive fails our test procedure on receipt, we can discuss the costs to repair it.

If we are unable to fit a DCC decoder in your locomotive due to size or other technical restrictions we will return it to you and refund you the amount paid less our usual delivery charge.

Whilst we always endeavor to use Gaugemaster Ruby Decoders, it may be necessary to substitute a compatible product.

We are only able to offer DCC decoder fitting in 00 and H0 gauge at this time.
