Hiiiiiiiiiii Wil,Sorry that it has taken me so long to get back to you,many thanks for your advise and time, in answer to your question 7215 "contactbus" is clearly brown and on the 7216 the "contactbus" is silver no coloured ring as on most Marklin
electric.One question remains,the "Fluit" how is that connected inside the train ?
My thanks go to the following:-
Huub, thank you for your discription.
Peter,thank you for the tip "marktplaats" I bought these items in case my own supply fails.
Peter again, at least now I know how it should sound! !
Kappa & KlaasZ, thanks for the humour, without it the world would be really flat!! Regards Fred.
