Very useful to have pages numbers ^ in an 89 page thread. Took me 30 minutes to locate this info. on page 59. My experience is similar. Loco stalled in a couple places that no other loco has ever stalled. As soon as I read the stuff about the worm cover popping off I knew that was the issue I had. As the boss sez the solution is easy, but fiddly. Removing all the little plugs and screws to get the circuit board, fans and decoder off needs a bit of careful work. All fixed now and loco running fab. Other issue is my irritation with Rails. As someone else noted I to ordered (inc deposit) in 2022. I am not in the UK and when I got the note about being short supplied and wanting to supply a non sound item professionally upgraded I accepted, but concluded others that ordered after me, but easier to ship to, were getting priority. I don't believe orders were shipped in the order they were received, and I dont like this. After getting this fabulous model I will order at least one 60. But it may not be from Rails.
