I was inspired by the work of Candido (Keith) so I set out to customize my PE cars.....
removed the hideous green plastic and installed clear windows
made the combo car the abandoned toy car
made the abandoned toy car an empty coach with hobo on the roof
improved the interior of the diner
installed a conductor in the coach
installed Kadees (Thanks to Laid Off Sick-Doug's tutorials on YouTube)
installed LED Light boards from GunrunnerJohn in all the cars
It was a big job that I would not have done without the insight provided by fellow forum members.
A big thanks to each of those guys!
