Well I received mine last Wednesday and took it to my friends for it's inaugural running session. it ran faultlessly for 1.5 hours in each direction. Now all run in it will receive a TTS sound chip and some decent speakers. I use a bass unit for the deeper notes and a higher frequency unit to bring out the higher frequencies. My only gripe is that Hornby are lax with their pacaging as this is the second model from them with postal damage. This time it was a minor crease to the top of the carton and retail packaging. last year my H Class turned up totally crushed, I couldn't even remove the model from the packageing. It was replaced by Hornby without problems and the replacement was perfect. Hornby,,,,, can you pack locos in bigger boxes with a bunch of foam chips to fill the voids, Hattons do this and I've had no damage ever from them! Nevertheless,,,onwards and upwards
