CNJ #592, an extremely rare survivor, is one of only 3 "modern" Camelbacks in existance and one of only two remaining CNJ steam engines. Built by Alco in 1901, this type of engine was designed to run on low cost waste anthracite known as culm. This coal needed a large grate area with a good draft to properly burn. Consequently, the cab was moved to the center for better visibility. Due to inherent dangers of the design, it was banned by the ICC 26 years after #592 was built. However, several railroads, such as the DL&W, Reading, Erie, B&O and 37 other railroads had such engines on their roster.
