Flyguy posted his 315 with the cars, here's mine.
That's the first thing I do when I get a car in, pull the wheels and do a general clean-up.The 315 set looks great. Love the K5s.
flyernut, that's a lot of cars for a 302 You must have had a pulmor.
I need to work on some axles and wheels, I get a lot of drivers slipping.
Mainly because wheels are not rolling good enough. If you remove the
wheels from the trucks and clean and oil, makes a huge difference. I
got a lot of cars and they barely rolled. Cleaned and oiled and they
will roll away from you.
Many companies use a similar type of quality control in preparing their products, such as liquids, oils, etc.Fwiw, regarding the rollability of train cars: I picked a few cars up awhile ago and at least one rolled very poorly. I did similar to what you fellows shared with cleaning and oiling, but then I thought how can I test rollability of my other cars and what standard to use? I grabbed some of my better cars, slanted a length of track and found the one that rolled the furthest. I now had a way to test and a standard to compare similar cars to.
