Here is a Life-Like passenger car, originally Amtrak Silver Inn 8053, after a rebuild for the Cape Ann. The detail molded into the dining area in the dome is quite amazing, but generally goes unnoticed since the entire interior is all molded grey plastic.
Step 1 (interior): A careful repaint in contrasting colors shows that each table has four place settings, silverware, coffee cups, napkins, and salt and pepper shakers! Here the carpet has been painted yellow, chairs Cape Ann green, tablecloths maroon.
Step 2 (not shown): Hungry passengers are brought in. It does require leg amputations to fit them into the seats.
Step 3 (exterior): The all-clear dome needs a bit of work. First, all the window frames are painted by running a silver Sharpie pen along them for a metallic look. The a roof panel is added, made from - what else? duct tape.
