Having recently acquired an SR N class through ebay I find that the original loco -tender coupling has been removed. Looking at the parts list I am at a loss as to how it was actually connected. Can anyone help? The previous owner claimed that the original device caused constant derailments.
Even more recently I acquired a GW Hall which threw a tantrum on every piece of poor track laying it could find -- are they really that sensitive (the other 30 odd locos rarely do!)
