Hello. I have a 0/27 train setup that I'm installing in a room which I plan on converting to a home bar area.
I purchased all new quick connect tracks for the entire length of the rail track. However the train loses power at most of the track sections. (I confirmed this is with a volt meter). I used lionel track cleaning fluid to clean all track pieces which helped some but still sections of the track does not work. I'm assuming the individual tracks are losing power at the connections to each other. Is there any way of cleaning these better to get track power? or is there any inserts that I could use at the power connectors to make it connect better?

Any help is greatly appreciated.
Thank you and have a great day.
