Locomotives can be significantly upgraded according to their age. Take the TRIANG XO4 motor, for example - over 50 years old, it can easily draw more than 1 amp, which is excessive for modern controllers and DCC technology. The ideal solution is to replace the original motor with a new, easy-to-install motor using an adapter. These advanced motors draw up to ten times less current, making them far more efficient and quieter. Furthermore, we provide a range of modifications to tackle any remaining flaws, ensuring your model operates at peak performance.
