Ron, As far as I know we've never had aproblem at Bromsgrove. Passenger car wheelsets are loctited onto their shafts ( only the 5" rails are track circuited and we have some 3 1/2" locos). I've got some scrap ones in the garage, so if I get chance I'll check them over the weekend - it's too dark & cold at the moment! Good question though!
