    One of the M7s has been in Works. I discovered that the bogie did not easily slide across laterally as designed by Hornby. This was partly due to some slight moulding flash on the top of the bogie; this has been reported by others elsewhere. The other cause was the Hornby retaining tube for the bogie. This needs to be positioned high to allow the bogie to hang loose from the body. If the bogie is held tight, it may be free enough to move to allow some vertical movement of the axles but not enough to allow smooth lateral movement of the bogie, as I found.

    Correcting this has resulted in a marked improvement in track-holding through (bumpy) turnouts. It still does not like A switches though!
