Thanks for the comment Galen - good points all. Poor ballast or roadbed conditions could also lead to pumping ties - that would also be interesting to model.
I'm getting some of my inspiration from a 1929 maintenance cyclopedia, which has some great photos of then-current maintenance tools and processes. I've attached a photo of one of the Cyclopedia's pages showing an example of manual ballast cleaning. The lower photo shows a much more mechanized operation, and there are other machines of various complexity pictured on subsequent pages. Pumping ties are described in the text.
