Well, I had planned on popping mine open to help, but if that's a Lionel now, it won't help much. The caps dont look swollen
I'm glad for you GRJ has found this. I like it better if I have some thing to draw info from and I can't make out the numbering(lionel uses a lot of proprietary numbers too) GRJ likely knows this board already,.so I'm gonna chime in on the camera a sec. and chill. Maybe take down the numbers on the center chips on the heatsink.
Check to see if you have manual focus ability and/or a macro setting (flower/sky close/far) Auto-focus doesn't always work well up close. Another trick is to get focus then crop/zoom. It depends on the camera or phone. (next one, it would be a feature(s) to look for, (manual settings) The other thing is to brace the camera/hands,plant an elbow etc. and shoot as you calmly exhale... like shooting a gun actually. Small things need absolute stillness.
Any movement becomes blur unless you really speed up exposure time and open up for more light to compensate. I don't know if you've used a manual camera before but my buddy just got a phone whose camera graphics are set up like one. It shows arches mimicking what you'd see looking fwd down the length of a lens; all controls where expected, slide the dot along its arch like twisting a lens or sliding the iris iris open, etc. Really cool and 15mpx.
Anyhow, better close and small shots can help you see small detail you can't even see by eye, it will help in repair, model better, and take better "fun" photos to share.
I.e. if you know when your shot isn't right, you've beaten 30% of photography already. A decent camera and tips usually gets you another 30%. Time/practice another 30%, and natural skill or luck make up that last 10% 
My main issue is I'm shakey and don't like my controls. I have to open menu to make a change; pita.
