I am pleased to hear of one modeller, able to obtain new bogies from Bachmann c158. I have tried several times to obtain replacement part for the c158 form Bachmann direct, replies have indicated that spare bogies where not available to the UK market, as all parts where scheduled for assembly line in China.
In contact with another modeller on another Forum, was advised that a bogy new type retaining plate is obtainable from Bachmann at £10 for fitting to two bogies.
Bachmann now informs me that two types exists - push together of European couplings - perhaps a solution is on the horizon, when I figure out correct type fitted on my c158.
I bought the c158 last year on eBay - advertised as brand new and still boxed. What was failed to be mentioned how many years it had been stored away. A lesson has been learned, new doesn't mean it is the most current version.
