I wrote several months ago about my new PS3 engine I bought and not working properly. That "rant" was removed by moderators. As suggested by others, rather than rant and bad mouth product, return to MTH for repair which I did 6 weeks ago. Just got back today. MTH said it was cold solder joint(s) and to keep track clean. My tracks are kept so shiny now I can see my reflection.
So put PS3 on isolated test track as engine can't be found if other PS2 engines are on rails. Ran engine around track once. No change from before. If engine momentarily loses power on a switch or block insulation that PS2 ignored, the new PS3 stops and brain dead, needing factory reset and re-add to get going again.
So $400 shelf queen and lesson learned
Of course Mr Melvin or Miller will delete this no doubt.
