Flash: The F-3's are from the early 1990's. They were shown with a string of highly polished aluminum cars with smooth/mirror finished roof's; a rather impressive line of cars. While they were shown together, they were open stock sales. The observation car is a Vista Observation, something new for LIONEL at that time; as well as an add-on of a duplex sleeper and a full length vista-dome car. A super set (?) only exceeded by the year 2000 Super Santa Fe Anniversary Set!
The F-3's will probably need some service to clean up the commutators on the motors and the brushes and brushplates. Lubing the motor housing bearing and the thrust races and washers and the top of the armature will have the motors run smoother. Fresh grease in the gearbox can only improve performance. This unit should have early Railsounds (2.0) in the companion Dummy A. Not bad for its time, but the horn is multi chime, not a single. Strange, as we all heard this then and when they finally got it right; some of us were disappointed in the "flat" sound of the single horn!
Be sure to lub the axle bushing on all the F-3 chassis, so they will roll easily.
Check the axles and wheels on the aluminum cars for wear, as grease alone will not take away the drag if they are worn down.
There is a illusive companion F-3B unit # 8103 that was short run to add to the trio. Can be found for sale from time to time at various prices - shop around. Story goes, that they were in such short supply, that LIONEL in Mt. Clemens, MI., when they were running the Santa Fe Train, even had a sign on their layout that stated;" even we could not get one"!!!! I think that was to defray some of the flack that were getting when people had a hard time purchasing one and complained. Hope this helps and have fun running them. Dennis M.
