Being trapped in the house because of the blizzard this weekend, numerous posts on the forum about O-gauge people stimulated me to populate some passenger trains. It has been awhile since I last put little people into my Rail King 027 cars, so I forgot some of the lessons I learned the hard way.
The most significant mistake I made was chopping-up 1:50 size people to fit into the seats of my Rail King cars. 1:50 figures are too big and they look poorly when viewed through the windows. The lesson I forgot is that 1:100 size figures fit much better, and overall give a good impression of a crowded passenger car.
I suspect that the interiors of other sizes and brands of passenger cars also have interiors with seats that are too small for 1:50 size people, and that's the raison d'etre for this post.
This time I used Liquid Nails Small Projects Repair Adhesive which comes in a convenient size tube. The Liquid Nails adhesive gets tacky enough in a few minutes to glue standing people, and it dries clear in a couple of hours.
Oh, and here's another tip. To get the roof off of a Rail King passenger car, remove two screws (#1 Philips) from the bottom of the car, one at each end, and they are the second screws in from the end that are in recesses shaded by the trucks. After removing the screws, grab the car at each end and twist it until the roof pops.
While you have the cars apart, consider adding window shades.
