I've had a partial rake of Maroon Bachmann Mk1s in operation for some time, but added several new ones recently.

A reorganisation of my fiddle yard and relocation of train sets highlighted a problem with the bogies on these.

One of my new SKs kept derailing and on further investigation there is enormous play in the outer axlebox of one of the bogies to the extent that the wheels almost drop out. Has anybody else come across this problem? I will need to 'fill' the axlebox and remake the hole, or fit brass inserts. On checking some of the other bogies the outer axles on several are not much better!

I've contacted Bachmann over the problem and hopefully they will supply new bogie frames.

As usual I think it is a quality control problem. I am assuming that the holes for the axle ends are moulded in at the same time as the rest of the bogie frame is produced and it would seem that these holes are rather oversize in a number of cases. With the axles being the pinpoint type the more play there is the more damage is done to the hole as the vehicle runs.

I think you are right 34C as on further study of the components it looks as if the inside of the bogie frames are badly moulded.
