    Is this a converted APT carrage?

    this must be APT-P coach 48204, a trailer second modified to take two BT32 non-articulated bogies. originally it had two BT11(?) articulated bogies which it shared with neighbouring coaches. modified as a test car for a proposed APT-U project (essentially same vehicles in different formation) - see http:/ for full details

    Did you mean "modified to take two BT12 non-articulated bogies".


    co-designer, BT12 bogie

    apologies david!

    i'm sure i remember reading it somewhere as BT32 - i knew the BT12 non-articulated bogie already existed, i assumed this was a modified versh to fit under this coach

    sorry! ;-)

    did the BT11 bogies pre date the ones on the French TGVs and if so did they use our technology to design their bogies
