Non-magnetic wheelsets for BR blue era coaching stock

[9C85]

I am in the process of building a BR Blue/ early sectorisation era parcels/carriage sidings layout and I have opted to use kadee couplings. I don't have a lot of stock at present. For my parcels stock, I have two new BG coaches (one Hornby and one Bachmann) which have the Kadee coupling in the NEM pocket.  I also have two old Hornby CCTS and a Lima GUV on which I have hacked off the tension lock couplings and fitted either the Kadee with the gearbox or built up  (down?) a base with plasticard and attached Hornby NEM pockets.  I have installed a delayed action uncoupling magnet at the entrance to the sidings and so far things are working pretty well on the fixed rake passenger train.  BUT, I have noticed that on the parcels stock, which is loose coupled, sometimes the last coach to be dragged over the magnet will detached  (like a slip coach). Further investigation revealed that the wheelsets are attracted by the strength of the magnet and this 'retards' the coach as it passes. Are there any commercially available non-magnetic wheelsets that I could use to replace the current ones? Thanks in advance

Bachmann have brass wheels but kept the steel axles which can still be affected magnetically. but only for wagons

This has been covered before, here for example. My favoured solution for the odd vehicle is to glue a small piece of foam to the underside of said offender so that it presses on the axle thereby introducing a little frag on the vehicle. Simple but effective.

I have just obtained a decent amount of foam insert material from 'peli' cases (hardcases for cameras etc). I am going to use it for 'crash barriers ' at the ends of myself layout but I have just tried putting a small piece of foam between the axle and underside of the offending stock. I only tried it out by pushingthe stock by hand ( will try with locos later), but the both BGs and the CCTs behaved a lot better, but the lima GUV  needs a bit more work  (or I might stick it on the far end of a sidings with 'COND' written on it .  Thanks for the suggestion.
