Welcome to the Strathpeffer Junction shop. UK shipping for OO Gauge ringfield adaptor kit orders is £2.99, irrespective of how many are purchased. We also ship to Ireland, mainland Europe, USA, Canada, Australia and New Zealand. Due to lockdown restrictions and our reliance on a mobile post office, parcel-sized orders are currently dispatched at Tuesday lunchtimes weekly, while letter-sized orders are dispatched twice weekly.

EU Orders
Due to recent VAT changes in the UK & EU, orders shipped to the EU will now be liable for Import VAT. How that charge is applied (as well as any admin fees) will vary from country to country, but in most cases you will be asked to pay these fees before the item is delivered to you. You can also buy our kits on eBay, where Import VAT is covered in the postage costs.

12V (12mm x 24mm) CD/DVD Motor for Lima or Hornby Conversion & Upgrade


Only 3 left in stock


A brand new 12v high-torque CD/DVD can-style motor, as featured in our Lima and Hornby upgrade kits. With the correct wiring and components, these can be used on DC and DCC layouts.

This 12mm motor is the most robust option for CD motor conversions and will fit most bo-bo diesel models/DMUs/Railcar, but not those with co-co bogies, tank engines or Lima’s Class 08/09 (without modification to the motor enclosure).

This motor is rated at 12 volts (D/V 13.0) and doesn’t require a voltage dropper to be added into the circuit, making it a simple and resilient upgrade. However, it will run a little slower than 6 volt (D/V 5.9) CD/DVD motors, so those seeking the fastest possible speeds for HST sets etc. may still prefer our 6V option.

Motor diameter: 24.2mm
Motor height: 12.2mm
Shaft diameter: 2mm
Shaft length: 5mm
Voltage range: 1.5V~12V
D/V:  13.0V

Please note: Unless you are buying this motor as a replacement for one provided in our conversion kits, you will also require a replacement drive gear and other materials to complete a conversion.

Important considerations

1.  With all CD-style motor conversions, it is good practice to: i) maintain very high speeds for relatively short periods only, ii) keep running on steep inclines to a minimum, and iii)  avoid coupled up with excessively long rakes of coaches/wagons..

2.  It is recommended that locomotives fitted with our 3D printed adaptor kits are not run for more than an hour continuously; this is to prevent the motor temperature from exceeding the glass transition temperature of the plastic.

3. We recommend that locomotives fitted with can-style CD motors are:

★ Not run without a DCC decoder as ‘Locomotive 0’ on a DCC model railway layout (this is will lead to over-heating and rapidly ruin the motor), and

★ Not placed on the tracks whilst a high frequency track cleaner (such as the Gaugemaster HF-1/HF-2)  is in operation. There have been some reports that the frequency can damage the motors, although it is not something that we have tested.


We can accept no liability or responsibility for any damage or injury occurring from the installation and use of our motor replacement kits. Installation requires modifications and the use of tools, some of which have the potential to damage you and/or you models, as well as other components and equipment. Users must not commence work unless they are confident that they have the skills and experience necessary to complete it successfully, and install these kits and undertake work to their models at their own risk.
