Thanks Jim. Thanks to you I figured out the door problem.
The tool you see:
   

Is Micro Mark's Micro 'Yankee' hand drill. I use it on all my grab iron replacing projects.
 Micro Hand Drill, steel chuck holds bits from #61 to #80, drill wood, plastic, thin brass quickly, for delicate drilling (micromark.com)

I completed the models up to painting this morning:

   

I finished off the door and door mechanisms on the bottom.

   

And added the brake gear to the 'b' ends. I used a brake set from detail associates that worked for the brown car, including the platform.

   

I then added the interior gussests on both cars. The gray one came from a Tichy kit and fit quite well.
I just washed them with some soap and water along with two other projects and I'll paint the primer coat when they dry.
