NZRedBaron Posted November 30, 2014 Share Posted November 30, 2014 I recently bought a second hand Hornby (from their 1973 range) Holden B12 in LNER Apple Green. I've been trying to run it in on my testing loop line, but it's being very recalcitrant, especially when it's running light engine, tender first; the rear axle of the bogie keeps jumping the rails and bringing the loco to a stall. Any advice on this? Link to post Share on other sites More sharing options...
RMweb Premium uax6 Posted November 30, 2014 RMweb Premium Share Posted November 30, 2014 I would look at the bent bar that the bogie pivots on. It may well have been bent so that the bogie doesn't sit flat on the track. Andy G Link to post Share on other sites More sharing options...
Boris Posted November 30, 2014 Share Posted November 30, 2014 In addition it could also be that the motor brushes are life expired, this can certainly cause poor running or something as simple as the wheels are badly worn as the model is 40 years old, I had this with a similar loco and had to rewheel the pony/tender.

NZRedBaron Posted November 30, 2014 Author Share Posted November 30, 2014 Well, that would explain the racket it made as it went around. *Goes to look* Huh, you were close, uax6; the rear axle on the bogie is slightly bent, so the wheel is wobbling. Well, I got a 1978 B12 model in storage that's lost its' pickups, so transplanting the bogie from one to the other shouldn't be too hard.... Link to post Share on other sites More sharing options...
PGC Posted November 30, 2014 Share Posted November 30, 2014 As Hornby are now releasing J15, D16/3 and K1, I wonder if they will re-release the B12, but to modern standards with a proper length body etc. That will save me having to buy and make the PDK kit! :-) Phil Link to post Share on other sites More sharing options...
NZRedBaron Posted November 30, 2014 Author Share Posted November 30, 2014 Speaking of new toolings, my 1973 B12 has blind centre driving wheels (That is the right term for wheels without flanges, right?). Can anything be done to correct that? Link to post Share on other sites More sharing options...
RMweb Premium uax6 Posted November 30, 2014 RMweb Premium Share Posted November 30, 2014 You could put a set of the flanged drivers on it, although it <may> not go round some of the tight raduis corners you might have... Andy G Link to post Share on other sites More sharing options...
