Notes:
- Easy to open: Two screws at the bottom between the bogies.
- Space for IR receiver in the speaker hole between the bogies.
- IR cable routing through the speaker cable hole, but too small for plug feedthrough (solder to IR receiver after threading cables).
- Space available for buffer capacitor (1000 µF), but Cap+ not connected to PluX22 plug → cables must still be soldered to the CTC locomotive module.
- Buffer capacitor can be soldered to the CTC locomotive module before installation.
Conclusion:
- Easy to open.
- Simple conversion.
- Soldering only required on the IR receiver.
