Jacob, I swapped the con rods around and replaced the bottom half of the body, (the old pannier tanks came in 2 parts and I had a spare bottom), replaced a coupling rod, full service and resoldered the loose wire. It runs really well(as the seller said it did!). I have donated the whole chassis/ motor to my old Jinty (my first choo choo), as this was an unreliable runner. The Jinty chassis/motor will be used for the Pannier Tank as I managed to solve it's minor problem. Will repaint it soon and use some spare GWR transfers I found in my 'box'. It's all working out very well!
