Thanks for the responses - the track was brand new the magnets are pretty strong and there does not appear to be any gaps at each interception - there are two small contacts in the middle of each piece that are pulled together by the magnets - i check them and they all are clean - i did notice that if i press down on the rails near where the track joins - i get a little voltage response but not consistent - not sure if the rail is connected properly - i checked for continuity between track sections and only had 75% good - 25% had no continuity - i may just use the straight as a test track - but the quality of the connections is poor - BTW the track is very level and ni gaps - still dent work
