Track issue? Train stops at 2 points

[Paul N scale]

 Hello,
 I am new to this and thought I had all of my research worked out before I started
the current layout.
 I first received the DCC Whistle Stop set to try out, it worked fine, so I immediately expanded.

I have an issue with train stopping and not working at all past 2 points.
I may have a reverse loop problem already, but I am not sure.
AnyRail does not show a reverse loop issue with this layout, but will after I make connection on the top
right side in the future.
As of now the layout is shown and the problem area is shown.
I have tried with 2 separate Engines.
Any help will be appreciated.

I got it fixed, found out how finicky the track joints can be.
All is well.
