I have a loop of Fastrack (43+/-Ft) no switches 060 curves.
The track is clean. (Used Acetone)
Powerhouse 180 transformer. Should the track (empty) show 18 volts all the way around? It doesn't but then my gauges are pretty inexpensive (Harbor Freight and a K-line box car with a meter build in). The meters indicate a few dead spots but they are +/- an inch and they are located where the track is joined . My VL Hudson will run on this track but not as good as it should, there is a spot where after the engine travels 3-4 loops the engine will stop, not short out just stop. A little push and it will run some more.
Moving the Hudson to the VL BigBoy loop and it runs great. ( Bigboy is off track)
Will a redo on the cleaning, I mean take it off the loop disconnect every piece and while at it check the electrical connections be worthwhile or just break the bank and order new track, This track is about 10 years, as long as I have had the Hudson and it was pre ordered.
Thanks

If you have tight electrical connections and more than just one power connection on 43' of track, the voltage should read within a few hundredths of a volt everywhere. If you are running two Legacy engines in command mode and one stops and the other doesn't it could be that the pickup roller spacings are such that one engine has all its rollers on a dead track, but the other one doesn't.
I wouldn't think the track would wear out, but in my experience the track pins on FasTrack are troublesome particularly if you keep taking the track apart. I have tried the pin bending tricks (see Lionel video) and the rail crimping techniques that are recommended, but unless the track is secured I found that the connections can lose electrical continuity just by running trains around the loop. Most of the continuity problems I have seen are with the 10" straight.
What you are describing is typical of some poor connections somewhere. You can find the spots by using a lighted piece of rolling stock or by checking continuity from one piece of track to the next using a meter set to measure resistance. Of course you want the power off when you do that. You don't have to take apart the whole loop, just make one break and then test continuity across each of the rail joints. As I mentioned, however, even when you fix all the connections, you can lose continuity as trains are run. For the grandkids, I duct tape the side of the roadbed to the floor after making sure all the connections are tight.
