This is what I managed to accomplish today. I tend to weather my rollingstock in groups of 10 or 15 since I have a long way to go. This time I experimented with pastels. The NP reefer was added to the collection because I like the look of silver. However, after making it look 20 years old it is no longer silver. The GN reefer is a mix of washes and pastels. The auto rack is straight pastels and the Rail Yard models coil car is just a airbrushed grime. I also airbrushed grime over the other 4 cars. The GATX pressure hopper was weathered with pastels and grime.
