Volcanic! We steam photographers love a good plume, and no single locomotive type produces a classic Vesuvian plume as reliably as a Shay. Here, we find the 1905 vintage Shay #5, the oldest Shay at Cass, performing a historical re-enactment of the eruption that wiped out the ancient Roman cities of Pompeii and Herculaneum in 79 AD.
For aficianados of geared steam engines, it's "almost heaven." Here are some scenes from the park's annual Railfan Weekends, as well as some private charters.
