It sounds like the gears have worn out or come adrift somehow. You will be able to get replacement gears from any of the Lionel authorised dealers Lionel Authorized Dealers or their replacement parts service Replacement Parts

It sounds like the counterbalance spring is loose or disconnected. I would rather add weight to the counterweight box to take some load off of the motor...Use fishing sinkers, one or two rolls of pennies or equivalent. Also do not overtighten the spring you will warp the base of the bridge.

There are 5 terminals on the bridge number them from outside to inside 1,2,3,4,5
Terminal 1 gets connected to the outside rails on a V,Z,VW,orZW transformer terminal U. The control button a #96 push button gets connected between terminals 2 and 3. Terminal 3 also gets a wire from A or B on a V or Z or Bor C on a VW/ZW. Terminal 4 gets connected to the transformer terminal D. Terminal 5 gets a wire to the lockon on the black bridge frame. The bridge needs 3 sections of track on each end seperated from the rest of the track as a stopping section remove the center rail pin on this section, This forms the stopping sections at each end of the bridge.

Just got my bascule bridge working.
1) cener rail should be ground (U terminal on my "V" transformer) and insulated from rest of tracks.
2) Power should rails should not be insulated from the rest of the tracks.
3) on my bridge there are 5 terminals (1 farthest from the track, 5 closest to the track.
4)Power to terminal 1 (on my "V" transformer that is from A terminal)
5)Terminal 2 and three are the two ends of a "Push Button Normally Off" switch (this switch send power across the motor and to ground at terminal 3.
6)Terminal 3 has two connections. The aforementioned switch and a ground connection at the transformer ( terminal "U" on my V type transformer.
7)Terminal 4 is a ground connection from the transformer ( "U" on my "V" transformer).
8)Terminal 5 runs a jumper wire to the center Rail on the clip connection at the free end of the bridge.

Good Luck
