I have since posting my Question checked the jioners, and have come to the conclusion
that all though the contacts, the track,and the locomotives are cleaned, and oiled and is running a little better,and im not an expert I believe that someone at one time has pushed the throttle wheele past the all full mark and it has caused the voltage to change to a deprumental levle,could this be the problem? and how do you troubleshoot this problem. thsnx chris(lilclw311)

If the track is the Bachmann G scale track, i would not be suprised if you are experiencing electrical conductivity problems at the joiners. Also, have you cleaned the wheels of the loco?

Sounds like the locomotive runs on some track and not others. If the set is old you may have trouble with the railjoiners having oxidized on the inside. If the engine is making noise when it runs it may need a little oil or grease on the moving parts/gears, use plastic compatible.

You might get faster and more accurate help by posting your question over on the Garden Railways forum.

My first impression is that you have a faulty power pack. If you have one designed for a smaller scale (HO or N), connect it to the track and see if the locomotive runs any better. Even though the train you're working on is G scale, it should run from any DC power pack. The main difference between power packs made for G scale as opposed to those for HO and N, is in the top voltage and wattage outputs. Most Model Rectifier power packs for HO or N scale, for example, are rated for 12 Volts DC output. A power pack for G scale is rated at 16 Volts DC output, and at a higher wattage; however, I have ran G scale trains using an MRC power pack made for HO scale with no problems.

Do you know what brand of locomotive and power pack you have? The brand name should be on the bottom of the locomotive and somewhere on the power pack. Also, try to avoid using sectional track with loose rail joiners, since these will give poor electrical continuity and that could be the cause of the poor performance of the locomotive.

I have been elected to put back together a very nice but abused train set. have so far cleaned track and lined it back up but the throtle box seemes to be malfunctioned i here feedback sounds from the locomotive when its runing.,and sometimes it gets stuck .oh by the way its a g scale train with about 3 hundred feet of track with turns swiches biuldings several diffrent locomotives tunnels and all its a verry buitiful set up . my question is ... is there any one who can advise me what steps to take to get this train to do what it was built for?
