[advice re' fitting tts to a rougemont castle]

many thanks for all your replies, I will try a sugar cube speaker first, if not satisfactory I will drill a hole in the tender (plan C)

Thank you for your email, the only entry into the tender is the point where the loco' drawbar pushes into what seems to be some kind of spring catch, has anyone else installed tts into this particular model?

i would like to fit a hornby  tts to above loco' which is from the red dragon express, the speaker is too large for the loco' and will obviously need to be fitted in the tender, however I cannot see any way to feed the speaker wires through the back of the loco' and into the tender apart from drilling small holes in both which I am reluctant to do to a new locomotive. Any help or advice would be greatly appreciated, many thanks.
