Lionel Prewar #616E Flying Yankee Passenger Set: #616, #617, #617 & # 618. TESTED AND FOUND WORKING GOOD. FORWARD AND REVERSE OK. VESTIBULES LIGHT UP(FLICKER WHEN MOVING). LOOKS LIKE SOMEONE INSTALLED A WHISTLE MECHANISM INSIDE BODY BEHIND THE MOTOR? I COULD NOT GET IT TO WORK. BODIES LOOK GOOD WITH NORMAL EXPECTED WEAR AND TEAR FROM AGE AND USE.
