Interesting Columbo. Are you saying in fact that the bogies didn't have sufficent longtitudinal movement to allow them to 'tip' or 'rock' as they negotiated your pointwork and as a result one or more of the wheel flanges was rising above the rail head. If that is what was happening doesn't that put a question mark over the longtitudinal level of your track? I suppose but fact that the rest of your stock is OK the level can't be that far adrift though. I must admit, I did have a similar problem with a rake of Bachmann BYA's but that on investigation that turned out to be the screw that retains the buckeye coupling plate was fouling the the bogie and preventing it from 'rocking' on its king post.

Apologies if I appeared to have been knocking your track laying ability, that certainly wasn't the intention. As I said, the fact that you are not having a problem with your other stock suggests that the problem is not with your track. I don't have any Hornby Gresley coaches but did experience a similar problem with the Bachmann BYA's, BRA's and HTA's but with these vehicles it was the top of the bogie frames fouling the screw that retains the body mounted buckeye coupling. With these it was simply a case of removing the screw as it was not required being that I use bogie fitted Kadee couplings. I realise that the bogies of all vehicles need a certain amount of lateral and longtitiudinal movement in order to cope with the cross level and lontitudinal discrepancies of our track especially in the vicinity of the frog of points where one wheel always tries to drop into the gap caused by the frog. Interesting, there has been quite a lot written in various forums and magazines with regard to the Hornby Gresleys and their disposition for leaving the track, although from what I gather this has more to do with the coupling arrangement than bogie free play.
