Igor,
The OCCRE motors were poor. Apparently not sold anymore.
1) For a Barcelona OCCRE tram, I bought 10 years ago in England one set made of laser cut wood, plastic gear and 2 chinese motors.
The motors were burnt after 3 hours.
Disappointed, I decided to find something solid (all steel and brass - no wood nor plastic, Swiss motors, ...)
In France, the "Micro Modèle" shop has sold a kit of gears + support + mashima motors.
"Micro Modèle" shop sells now a set from Romford.
Easy to find in the UK.
It seems that the running axle gear is 3/16. This MIGHT??? fit a Tenmille wheelset. To verify by UK fans.
See my Barcelona OCCRE model:
Barcelona
There is a picture with the "anglo/chinese" unsuccesful solution, then amongst the last pictures, the "French" robust solution with Mashima motors and UK Tenmille spoked wheels.
Note: all of this is +/-10 years old, ....
2) As I was planning various models and like robust solutions, similar to real trams motors and trucks, I have designed:
- an "universal" compact motorset that fit a bogie, can be used under floor and is powerful with a Swiss 6-8Watt Maxon motor.
- a BRILL 21E truck that I have used for an OCCRE Istanbul (done), Buenos Aires (in progress), Soller and Lisbon (in stock)

3) I have designed for a club and produced about 20 motorcar and 20 trailers kits of Belgium trams. (does not fit Occre models)

4) for two heavily customized Bachmann trams transformed in Cairo motor car and matching trailer, I have designed a specific truck
