It has only come available in the U.K. this week and is not yet on the internet.
You could try telephoning your direct service in case it is the same in France.
The best way is for people who want the bits, is for them to write to Playmobil.
I am only one voice the more people write the more they know how many people are feeling the same.
you can get yellow quartz from the 3670 RC car set.I have 5 extra battery holders (GREY). I purchased a lot when playmobile was getting out of the old style RC trains. These are the holders that fit the 1996 vs of the trains. I am looking for green and yellow chip sets for the trains, or other ideas on how to change freequencies. I am now running 8 trains, and need to manually turn on an off etc. Would consider trades
