performances between Williams F-3 and GP-9

You will have differences between the newer and older Williams as the circuit board too may have different output voltages because of electronics used in them. Williams has used many different circuit boards over the years.

I have only the older Williams before Bachmann engines, I don't have any of the Williams by Bachmann because of reading stuff on the online forums about how the circuit boards were failing on the new Bachmann/Williams engines about three or four years ago.

Also about the wobble; have you taken the motor mounting screw out and re-assembled the motor to the truck assembly? When you re-assemble make sure the flywheel can turn the wheels easily without binding. Sometimes the mounting screw can come loose from use as it did with me on a Williams SD-45.

Electronics are different for sure.....may be part of the difference. 

And the gears may be different ratios unless you disassemble both trucks and count each gear tooth. A few teeth difference can make a difference.

Last thing is motor windings. Only way to check this is remove motors, run free wheeling and test RPM...... not worth the efforts really. 

Hello guys and gals......

This is interesting because I am sure that a lot of Williams owners probably didn't know about this as did I.  This makes a lot of sense.  Is there anything more to learn the differences between them ? This make me like the older Williams better in case the older Blue and silver F-3's which is my favorite Williams locomotive.  what about you guys ?

The older Williams engines before Bachmann seem to run very well and not have any problems. There was a minor problem with direction control but I fixed it be removing the circuit board and replacing it with a bridge rectifier.

The other thing I don't like about the new Williams by Bachmann is there is very little road name selection and the prices on the website are way too high for me to buy any new WBB stuff directly from Bachmann.

hello guys and gals........

Did I paid too much (275 dollars plus tax from the western depot?) for my mint in box older Williams Blue and Silver F-3 "A A" units ?  I also put the matching "B" unit on

Lay-away (130 dollars plus tax)
