Selling a Used Mth premier union Pacific F3 ABA set. Item number is 20-20351-1. Proto sound 3. Engines will run on O31. I run conventional with a MTH Z4000. All sounds work as do lights with operating MARS on both A units. Front and rear coupler operate too. Only flaws that I noticed are on the B unit with a red mark on the top and one side has the screen buckled. Both issues can be seen in the last photos. Please ask any questions, comes with original box. I can accept PayPal, money order or check. Email is in profile.
Asking $ 475 shipped CONUS with FedEx .
