What great advise , and so promt....thank you all for the input.

I first checked the locomotive w/ a 9v battery and eliminated it as the problem. (worked fine). Then checked voltage at the track....nothing there....then checked output at connecter ....nothing there either. I took a chance and opened up the DCC controller to peek inside and I got lucky. a little piece of solder fell out when I opened it. Had a bad solder connection at the output plug....the wire was not making contact.
Such a relief, I drove the locomotive around the inner loop. Now back to building my layout. Again , I am so grateful to y'all.
Thanks

My childhood dream was to have a train layout , but it was never realized. Worked all my adult life and never had time. Now I am forced to retire with cancer and I decided to do it before I die. So I bought a small Bachman starter set w/DCC control. It only came w/enough track (EZ track)to do a 36"circle. but I didnt care. I bought flex track and a sheet of 4x8 plywood and began building w/paper machete. I created an outer loop that takes up the entire 4x8 climbing a gradual grade through a mountain tunnel ,crossing a ravine, gradual grade back down to start over again. I had the entire middle area free so I created a turn out to a smaller oval inside the outer oval. So much work and having not laid any outer oval  track yet, I connected the inner oval track because I was hot to roll , and the inside was flat. I left the outside unconnected at each manual cutout, hooked up the DCC controller ,put my loco on the track and......NOTHING ! Ive been working on the layout for so long, that the instructions have been misplaced, so I got online....read where the loco was probably set to #3 on the DCC control. STILL NOTHING. .....Remember im brand new , but what could be wrong? I tried all the stations on the controller and even the one for non DCC engines. .....I dont have an older regular DC transformer to test the loco or another loco to try on my track.......so im at a loss. Any ideas?....what am I missing? any help is appreciated....I will continue working on the layout ,I have a long way to go. (much more work than I had imagined). Attached is an early photo of the layout.
