A big thank to Andromeda for the pictures. That will help a lot of 12V train fans. Enjoy you train Matthieu

Thanks JopieK, In fact my son (7 years old) is just interested now with my old Lego train. That's why we started to rebuild everything and I remember that 30 years ago my BB12V was a bit annoying with this default on the contact switch. I tried again to contact Andromeda, even if I've seen that's I was not the only one to try! Anyhow it's a pity to loose a knowledge, especially in those years with the facilities to exchange info. Sorry for the time spent with me. I loved Lego train, I'll love it again but fixing those sealed parts is not easy! If you have any other post explaining that, I would very appreciate. In fact I understand that specific topics like this one are not discussed very oftenly ! Thank again. See you soon. Matthieu

Sorry Andromeda, your work is mentionned all over Bricks forum as the best report on opening a BB12V, couldn't you post again few pictures to help us? I'm afraid to open my red BB12V as only one out of the 4 contacts switch below doesn't have any spring to connect with electric rail. Thanks in advance (Sorry for my "french inspired" english) Matthieu
