I just received my new GP30 Williams locomotive.  It is probably the best balance of detailed features, reversing unit and sound features I have seen yet. 

The horn and bell sounds are greatly improved from the Trublast II system.  It even has the sound of the engine and electric of the locomotive.

I am one who did not equip my layout for the complicated Lionel and MTH systems.  It is refreshing to see that you have stayed with a conventional system.  The lighting was another good surprise.  I hope that additional road names may come in the next year.  I would also hope that another EMD model might be tooled in the near future.
