Very productive day, cleaned all the building dust off the layout and whilst I was at it, gave the track a good clean with a piece of hardboard. I noticed that whilst rubbing the board round the track there were a couple of instances where the board ‘caught’ on the track - this happened where set track curves met flex track straights, on inspection there was a small lip on the join where one track was a fraction of a millimetre higher than the other side and I suspect is the cause of occasional stalling of locos at that point, running in the opposite direction is fine (going from higher side to lower) - happy to have solved that particular irritation! Also had chance to run and check Falcon after being returned from the paramedics in Margate, and again she is running very well - great customer support at Hornbythumbsup Also managed to run an auto calibration on all 4 of my locos and for the first time get all of them running on the layout at the same timegrinning
