I purchased this unit on sale a number of years ago with the intent of repainting it for the home road. But as I was getting rid of a number of old magazines recently, I came across the two-page color photo of 633 and 628 followed by two snowbirds in the June 2002 issue of Trains magazine which is shown below. The photo was taken in March of 1976- just five months before my time period. So not only did I have a period photo for weathering, but I also had both sides of the C628's. A little additional researched showed that 640 was an ex-Monon unit that was repainted into the Cornell Red scheme in 1974. And other than the end handrails, all of the details were correct. So the back story of leasing this unit was quickly developed and I went searching for additional photos.
The unit was weathered with a combination of Pan Pastels, oils, acrylics and even a lead pencil. The weathering is the combination of the various effects I found on five different photos of LV C628's.
The weathering process involved a number of different applications of Pan Pastels followed by Dullcote followed by more Pan Pastels followed by... well, you get the point.
The last step was to scrape a #2 pencil along a small section of the upper front and rear handrails. In studying the photo, you could see where the crews had worn the paint off and what was showing was bare metal. From somewhere out of the blue, it occurred to me that I could represent this with pencil lead.
This unit will be teamed up with a home road C628 and SD45 in the not too distant future.
