When Hornby release their versions of the ex-Lima models they will have been re-engineered to take a Hornby designed drive unit,-so Lima brushes,springs and traction tyres will NOT be remade as they are some of the components that wont be used in new production,and Hornby have no obligation[and why should they?] to provide a spares back-up for the now obsolete Lima designs,-almost certainly the bogies will be modified as well to do away with the non-standard[compared to Hornby]wheelsets,and the underframes probably modified in some way also,I expect these will become available in due course as spares,but of course they won't be interchangeable with the previous Lima equivalents...
For Lima spares try the previously mentioned MB
