It's been a long time since the posted review and very good it was too. I own a number of these wonderful locomotives(Gronks, Jockos) and I am very impressed with their performance and looks. My oldest "Jocko" is approaching its fifth birthday and runs just as well as when first run in. My latest "Jocko" I have had for a week and it is in the process of being run in. These are still brilliant locomotives. Some of Hornbys finest.
