Further to my post of last Friday, I have received the new material, the Jinty was pre-owned and i decided to have the chip hard wired by Hattons themselves since it is becoming increasingly difficult for me to handle very small parts like the screws used to hold the bodies in place on the chasses and other small accessories. I fitted both the autotrailer and the locomotive with kadee couplers, put a composite brake coach between them and set them running. The whole outfit runs very smoothly. I only have to give the locomotive an apprpopriate address now.
