Well the main issues on mine are glue (or lack of) while removing the cab one horn moulding pinged off and to the floor, once the cab was off one of the cab walls fell foul of a lack of glue, once reassembled and put on the track there was a alarming knock which came from the con rods hitting the steps on one side. Apart from those minor niggles which can be cured with some good glue it is superb, the quietest runner in the fleet and can haul more than I'll ever need.
The remaining jobs to do are to reattach all AWOL parts, attach the extra detail parts, modify the head code lighting by thinned down yellow paint and finally attach a head code. Simples!
